Advantages of AC synchronous motors include:
Precise speed control: Synchronous motors maintain a constant speed with variations in load, making them suitable for applications where precise speed control is necessary.
High efficiency: They offer high efficiency due to the absence of slip (the difference between synchronous speed and actual rotor speed) found in induction motors.
Power factor correction: Synchronous motors can be used to correct the power factor in electrical systems, leading to improved system efficiency.
Constant torque: These motors deliver constant torque at synchronous speed, making them suitable for applications with constant load requirements.
Common applications of AC synchronous motors include:
Industrial machinery and automation
Electric clocks
Electric fans
Robotics
Compressors
Pumps
Machine tools
Electric vehicles (PMSM)
