What is Stepper Motor

A stepper motor is an electric motor whose main feature is that its shaft rotates by performing steps, that is, by moving by a fixed amount of degrees. This feature is obtained thanks to the internal structure of the motor, and allows to know the exact angular position of the shaft by simply counting how may steps have been performed, with no need for a sensor. This feature also makes it fit for a wide range of applications.

Benefits of Stepper Motor

High Precision and Control
One of the main advantages of stepper motors is their ability to provide precise positioning and control. Stepper motors move in discrete steps, allowing for accurate position control and reproducibility. This property makes them ideal for applications that require precise movements, such as 3D printers, CNC machines, and robotics.

High Torque at Low Speeds
Stepper motors are known for their high torque, particularly at low speeds. This characteristic makes them suitable for applications that require high holding torque, such as in robotics and conveyor systems. Stepper motors can maintain their position without the need for external braking mechanisms or additional power, making them highly efficient in certain applications.

Cost-Effective Solution
Compared to other motor types, stepper motors offer a cost-effective solution for many applications. They are relatively inexpensive to manufacture and can operate with simple drive circuits, reducing overall costs. Additionally, since they don't require feedback sensors like encoders or resolvers, the overall system cost can be significantly reduced.

Easy to Control
Stepper motors are driven by digital pulses, making them easy to control and interface with microcontrollers or other control systems. The simplicity of their control system allows for straightforward integration with various electronic devices and automation systems. This ease of control makes stepper motors popular in hobbyist projects, prototyping, and educational applications.

No Servo Tuning Required
Unlike servo motors, stepper motors do not require complicated tuning processes for optimal performance. Servo motors typically need careful adjustment of gains, feedback loop parameters, and damping coefficients to achieve stable and accurate motion control. In contrast, stepper motors offer plug-and-play operation, simplifying the setup process and reducing the time required for implementation.

Types of Stepper Motor

Bipolar stepper motor

A bipolar stepper motor has an onboard driver that uses an H-bridge circuit to reverse the current flow through the phases. By energising the phases while alternating the polarity, all the coils can be put to work turning the motor.In practical terms, this means that the coil windings are better utilised in a bipolar than a standard unipolar stepper motor (which only uses 50% of the wire coils at any one time), making bipolar stepper motors more powerful and efficient to run. Although bipolar stepper motors are technically more complicated to drive, they tend to come with an inbuilt driver chip that handles the bulk of the necessary instructions and behaviours.

Hybrid stepper motor

Hybrid stepper motors allow for yet more precision, through techniques such as half-stepping and microstepping. Microstepping is a way of increasing the fixed number of steps within a motor by programming a driver to send an alternating sine/cosine waveform to the coils. Doing this often means that stepper motors can be set up to run smoother and more accurately than in a standard setup.Hybrid stepper motors usually have poles or teeth that are offset on two different cups around the outside of the magnet rotor. This also means steps and rotations can be more precisely controlled, as well as offering quieter operation, higher torque-to-size ratios and greater output speeds than standard stepper motors.

Application of Stepper Motor

3D Printer
Stepper motors are essential components in 3D printers due to their precise control over the position and speed of the motor.Unlike traditional DC motors that rotate continuously, stepper motors move in small steps and enable precise positioning and holding of the printing head. This precise positioning is essential for creating 3D models.Stepper Motors also provides high torque at low speeds which ensures the printing head can move smoothly and maintain its position under different load conditions. This motor also offers excellent holding torque which prevents unwanted movement during printing.

CNC Machines
Stepper motors are a crucial component in CNC machines due to their unique characteristics of precisely aligning with different operating systems as per the requirement.Stepper motors have the ability to move in discrete steps with the help of electrical pulses, which results in exceptional positioning accuracy and repeatability. This precise control enables the creation of intricate designs with minimal error to ensure high-quality outputs.Stepper motors also offer excellent holding torque, which allows them to maintain their position even under different load conditions. This feature prevents the unwanted movement of the CNC machine during the operation. This feature is important in machining the intricate parts that require precise positioning and stability.

Robotics
Stepper motors are extensively used in robotics due to their exceptional controllability, precision, and torque.Stepper motors offer precise angular positioning and control rotation which makes them ideal for robotics applications that require accurate movement and fine control.Unlike traditional DC motors, stepper motors divide their steps into smaller steps, enabling precise positioning and accurate movement for the manipulation of robotics joints and effectors.Additionally, stepper motors offer high torque at low speeds which enables robots to handle heavy loads and overcome the initial forces effectively.

Industrial Automation
Stepper motors are widely used in various industrial automation devices such as conveyor belts, pick and place machines, and various automated systems due to precise positioning and accurate movement. Stepper motors have precise angular control and the ability to be easily integrated with digital control systems which makes them ideal for applications that require precise and repeatable movements. Stepper motors also offer precise positioning and control over the speed and direction of the motor which enables the accurate movement of the objects and becomes an ideal solution for conveyor belts and pick-and-place machines.

How to Choose Stepper Motor

Inertial Loads
Inertia is a measure of an object's resistance to a change in velocity. The larger an object's inertia, the greater the torque required to accelerate or decelerate it. Inertia is a function of an object's mass and shape. A system designer may wish to select an alternative shape or low-density material for optimal performance. If a limited amount of torque is available in a selected system, then the acceleration and deceleration times must increase. We recommend that the ratio of the system inertia to the rotor inertia not exceed 10:1. A gearbox may be used to help achieve this ratio.

Frictional Loads
All mechanical systems exhibit some frictional force. The designer of a stepper motor system must be able to predict elements causing friction within the system. These elements may be in the form of bearing drag, sliding friction, system wear, or viscosity of an oil-filled gear box (temperature dependent). The selected stepper motor must be able to overcome any systemic friction while providing the necessary torque to accelerate the inertial load.

Positioning Resolution
The positioning resolution required by the application may have an effect on the type of transmission used and/or selection of the stepper motor driver. For example: A lead screw with 5 threads per inch on a full-step drive provides 0.001 inch/step; Half-step provides 0.0005 inch/step; A microstep resolution of 25,400 steps/rev provides 0.0000015 inch/step.

How to Use a Stepper Motor

Step 1: Materials That I'm Using
In order to demonstrate how to use the stepper motor (a hybrid stepper motor), there are a few things that I will end up using.

Step 2: Stepper Motor Theory
Stepper motors are part of a class of motors known as brushless motors; these motors have a shaft but it does not physically touch anything in order to rotate. Rather, stepper motors work by utilizing electromagnets that are concentrically located around the shaft.The idea behind electromagnets is that when a voltage of any kind is applied to a coil surrounding the piece of "soft" metal, that metal becomes magnetized until the current stops flowing through the coil. The central shaft rotates as the coils surrounding the electromagnets are brought to various voltage states.

Step 3: Types of Stepper Motors
There are three main types of stepper motors that exist: Variable inductance motors, permanent magnet motors, and hybrid motors. Variable inductance motors only use the generated magnetic field to make the central shaft rotate and line up with the energized electromagnets. Permanent magnet motors are similar except that the central shaft is polarized to have magnetic north and south pole which will appropriately rotate to whichever electromagnets are turned on. The difference between this and the variable inductance motor is that the permanent magnet motor's central shaft does not have multiple "teeth"; Just a north and south pole.

Step 4: Unipolar Vs Bipolar Stepper Motors
There are two types of stepper motors: Unipolar and bipolar stepper motors. On a fundamental level, these two types work exactly the same way; Electromagnets are turned on in a sequential fashion, inducing the central motor shaft to spin.The difference between the two types is the voltage levels. A unipolar stepper motor only operates with positive voltage, so the high and low voltages applied to the electromagnetic coils would be something like 5V and 0V. A bipolar stepper motor has two polarities, positive and negative, so its high and low voltages would be something like 2.5V and -2.5V.

How to Maintain Stepper Motor

The Importance of Regular Lubrication and Cleaning
Proper lubrication and cleaning are fundamental aspects of maintaining linear stepper motors. Over time, dust, debris, and other contaminants can accumulate on the motor's moving parts, causing friction, heat, and premature wear. Regularly cleaning the motor and applying suitable lubricants can prevent these issues and extend the motor's lifespan.When cleaning the motor, it is important to use non-abrasive materials and solvents that are compatible with the motor's components. Gently removing dirt and dust from the motor's exposed areas and ensuring that the internal components are free from debris is crucial. Additionally, lubricating the linear bearings, threaded rods, and lead screws with appropriate lubricants will effectively reduce friction and prevent excessive wear.

Implementing Proper Environmental Protection Measures
Linear stepper motors are exposed to various environmental factors that can affect their performance and longevity. Factors such as moisture, dust, temperature variations, and vibrations can have a significant impact on the motor's reliability. Implementing proper environmental protection measures can help shield the motor from these external elements, ensuring its optimal functioning.One effective method of environmental protection is the use of protective covers or enclosures. These covers can shield the motor from dust, debris, and moisture, preventing the accumulation of contaminants that can obstruct the motor's movement. Additionally, using temperature control measures such as cooling fans or heat sinks can help regulate the motor's operating temperature, preventing overheating and potential damage.

Optimizing Motor Voltage and Current
To maximize the lifespan of linear stepper motors, it is vital to operate them within their specified voltage and current ranges. Operating the motor beyond these limits can lead to overheating, excessive strain on the components, and eventual failure. Therefore, it is crucial to ensure that the motor's voltage and current settings are correctly configured.By referring to the motor's datasheet or consulting with the manufacturer, you can determine the optimal voltage and current values for your specific application. It is crucial to use a high-quality power supply that provides stable and accurate voltage regulation. Additionally, implementing motor driver circuitry with features like current limiting and protection mechanisms can effectively safeguard the motor from potential damage caused by overvoltage or excessive current.

Regular Inspections and Maintenance Checks
Performing regular inspections and maintenance checks is a proactive approach to identify potential issues or abnormalities before they escalate and cause major problems. These inspections should include a comprehensive examination of various motor components like the bearings, belts, gears, and wiring connections.During the inspections, it is vital to look for signs of wear, corrosion, loose connections, and other potential issues. Addressing these issues promptly can prevent further damage and ensure the motor's optimal performance. Additionally, checking the motor's mechanical alignment and adjusting it if required can prevent misalignment-related problems that may lead to premature wear and reduced lifespan.

FAQ

Q: Do stepper motors need maintenance?

A: Regular inspection is key to maintaining a stepper motor's performance. This involves checking the shaft for any signs of wear and tear, inspecting the brushes and commutator for damage, and checking the windings for any signs of overheating.

Q: Should you lubricate stepper motor?

A: Do not oil the X or Y stepper motors. The only motor that requires lubrication is the Z-motor and lead screw combination. (See lubricating the Z-axis assembly above.) Oiling the stepper motors can permanently damage the motors.

Q: How do stepper motors go bad?

A: It's possible, like a bearing fails. More often the wiring goes bad, or the stepper driver, or the driver overheats. Easiest first step is to swap the x and y motor plugs on the board.

Q: How do you maintain a stepper?

A: Stepper/Stepmill Maintenance and Repair for Home Gyms.It's a good idea to check the condition of the machine's alternator, belts, and other moving parts on a regular basis and replace any worn parts as needed. You should also keep the machine clean and free of debris to prevent any damage or accidents.

Q: Can you damage a stepper motor?

A: Lifetime of the coils derates with temperature, so leaving them powered up, even not stepping or under load, consumes operating lifetime on the motors. There are other wearout failure modes on the motor where bearings or shafts can fail when people get enthusiastic on belt tension which are related to motor movement.

Q: How do I make my stepper motor run smoothly?

A: It is accomplished by ensuring the drive and motor work together, and often by using microstepping. Microstepping is driving the stepper motor such that each pulse does not complete a full step. Rather, a partial step occurs. This allows the motor to operate far more smoothly at lower speeds.

Q: How can I improve my stepper motor accuracy?

A: With a standard, non-cumulative, accuracy of ±5 percent, the first and most logical way to increase accuracy is to micro step the motor. Micro stepping is a method of controlling stepper motors that achieves not only a higher resolution but smoother motion at low speeds, which can be a big benefit in some applications.

Q: How can I test a stepper motor?

A: Best way to test them is with a driver circuit and see if they step. You can use a silly scope to test the circuit is firing pulses properly and then try connecting a motor to the circuit. Just scoping a motor does not tell you about a physical problem like a seized bearing, bent shaft etc.

Q: What is the lifetime of a stepper motor?

A: Supplement: The service life of the stepping motor also has a certain relationship with the application environment, power supply voltage and load. The service life of the stepper motor used on the machine is usually less than 20,000 hours.

Q: Do stepper motors lose power over time?

A: In some cases, the motor runs normally for a long period of time but lose steps after some time. In that case, it is likely that the load seen by the motor has changed. It can come from the wear of the motor bearings or from an external event.

Q: What can damage a stepper motor?

A: Solution: Environmental factors such as welding, chemical vapors, moisture, humidity, dust, metal debris, etc., can damage the electronic components and the stepper motor. Protect drivers, controllers and stepper motors from environments that are corrosive, contain voltage spikes, or prevent good ventilation.

Q: Can stepper motors be repaired?

A: Stepper motors are especially difficult to repair due to their complexity: the controller, detent torque, encoder, rotor, stator, teeth, train pulse, and a variety of other machinations must all be working at optimal efficiency to provide the accurate positioning required of them.

Q: Can you fry a stepper motor?

A: I second that stepper motors are just a couple of magnets so frying them is fairly hard. That said I also briefly had a weird issue where I accidentally moved the gantry while the stepper was on and it wouldn't run before a couple of restarts and unplugging and replugging the motor on both ends.

Q: Is it bad for a stepper motor to skip?

A: Skipping steps is simply a little bit of a misalignment, whereas a full-blown stalling is when the rotor stops, and the current continues on around the windings trying to command it to move with the rotor actually stopped. This could be because the electrical windings are trying to move faster than the rotor.

Q: What is better than a stepper motor?

A: Servo motors are more efficient than stepper motors, with efficiencies between 80-90%. In overall performance, servo motors are best for high speed, high torque applications while stepper motors are better suited for lower acceleration, high holding torque applications.

Q: Why are stepper motors noisy?

A: This is due to the geometry of the stator/rotor teeth (a feature of all step motors) and peculiarities of the resultant B-fields. In short, step motors are complicated beasts and don't perfectly translate current waveforms into mechanical motion. The difference shows up as vibration, especially at higher speeds.

Q: Why do stepper motors get so hot?

A: Because of its high harmonic component and variable alternating current frequency in relation to speed, stepper motors typically produce heat. The motor's internal insulation level primarily determines the permissible level of motor heating.

Q: Can stepper motors get wet?

A: Some stepper motors are designed to be waterproof, while others are not. Waterproof stepper motors are typically sealed to prevent water from entering the motor and damaging the internal components. These motors are often used in outdoor applications or in environments where they may be exposed to moisture.

Q: How to improve stepper motor accuracy?

A: Another mechanical adjustment to gain accuracy in your stepper motor is to use a smaller inertia load. If the motor is attached to a large inertia when it tries to stop, the load will cause some slight over-rotation. Because this is often a small error, the motor controller can be used to correct it.

Q: How do I stop my stepper motor from stalling?

A: Stalls occur when the stepper motor is undersized relative to the load the system places on it. To prevent this, make the following calculations to identify motors up to the motion task: Define the motion profile. This means setting parameters such as required positioning time, acceleration and deceleration time.
