"Alternating current motor" is a machine used to convert mechanical energy and alternating current energy into each other. Compared with DC motors, AC motors have a simpler structure without a commutator, are more convenient to manufacture, and are relatively firm. It is easy to make a high-speed, high-voltage, high-current, and large-capacity motor. The convenient AC power supply also makes the AC motor the most widely used type of motor.
