DC gear motor is a widely used deceleration equipment, the main transmission structure by the drive motor (divided into brushless DC motors, brush DC motors), gear box assembled from the deceleration equipment, with deceleration, transmission, enhance the torque function; stepping motor is a precision drive motor, angle can be controlled, speed can be controlled, the application is also wide; the following will introduce the difference between DC gear motor and stepping motor.
DC gear motor and stepping motor.
DC Geared Motor:
DC geared motor, i.e. micro geared motor. It is generally used to achieve deceleration by meshing an electric motor, internal combustion engine, or other high-speed power through a gear with fewer teeth on the input shaft of the gearmotor with a larger gear on the output shaft. A DC gear motor consists of a stationary part and a rotating part. The stationary part is called stator. It consists of a housing and a magnetic pole. Of course, the magnetic pole is used to generate the magnetic field. The rotating part is called the rotor, also known as the armature. The armature core is cylindrical, made of laminated silicon steel sheet, the surface is punched with slots, and the armature windings are placed in the slots. A DC reduction motor is a machine that converts electrical energy into rotating mechanical energy. It is mainly used as electrolysis, electroplating, electrofusion, charging and excitation of alternators. Although a DC reduction power supply is required, power rectification components are also used to convert AC to DC, and AC rectification cannot be compared with DC reduction motors from the point of view of ease of use, reliability of operation, and certain operating properties.
Stepper motor:
Stepper motor is a kind of induction motor, its working principle is to use electronic circuitry, DC power into time-sharing power supply, multi-phase timing control current, with this current for the stepper motor power supply, the stepper motor can work properly, the driver is for the stepper motor time-sharing power supply, multi-phase timing controller. Although the stepper motor has been widely used, but the stepper motor can not be like ordinary DC motor, AC motor in the regular use. It must be used by the double ring pulse signal, power drive circuit composed of control system. Therefore, it is not easy to use a good stepper motor, which involves a lot of specialized knowledge of machinery, motor, electronics and computers. Stepping motor as an executive element, is one of the key products of mechatronics, widely used in various automation control systems. Stepper motor can also be equipped with a gear box (reducer), encoder use, plus the role of the deceleration device, DC motor as long as you add the right voltage will turn, and turn the number of laps is difficult to control, while the DC motor's operating current to be a lot larger, generally small DC motors with L298N such as a special driver chip driver, control is generally used in the output of the microcontroller PWM wave control; and stepping motors are According to the beat work, can rotate a very small angle.
