The working principle of electric motor

It utilizes an energized coil to generate a rotating magnetic field and act on the rotor to form a magneto-electric power rotating torque. Based on the law of electromagnetic induction and the law of electromagnetic force.

Classification of electric motors:

1. According to the classification of the operating power supply, it can be divided into DC motors and AC motors. Among them, AC motors are also divided into single-phase motors and three-phase motors.

2, according to the structure and working principle of classification, can be divided into direct current motor, asynchronous motor and synchronous motor.

3, according to the starting and running mode classification, electricity can be divided into capacitor starting single-phase asynchronous motor, capacitor running single-phase asynchronous motor, capacitor starting running single-phase asynchronous motor and split-phase single-phase asynchronous motor.

4, according to the use of classification, can be divided into drive motor and control motor.

5, according to the structure of the rotor, can be divided into cage induction motor and winding rotor induction motor.

6, according to the running speed classification, can be divided into high-speed motor, low-speed motor, constant-speed motor, speed motor.
