1. According to the different working power of the motor, it can be divided into DC motor and AC motor. Among them, AC motors are also divided into single-phase motors and three-phase motors.
2. Motors can be divided into asynchronous motors and synchronous motors according to their structure and working principle. Synchronous motors can also be divided into permanent magnet synchronous motors, reluctance synchronous motors and hysteresis synchronous motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are divided into three-phase asynchronous motors, single-phase asynchronous motors and shaded-pole asynchronous motors. AC commutator motors are divided into single-phase series motors, AC and DC dual-purpose motors and repulsion motors.
3. Motors can be divided into capacitor starting motors, capacitor running motors, capacitor starting motors and split-phase motors according to the starting and operating modes;
Motors can be divided into driving motors and control motors according to their uses. Drive motors are further divided into motors for electric tools, motors for household appliances, and motors for other general-purpose small mechanical equipment. Control motors are divided into stepping motors and servo motors.
4. Motors can be divided into cage induction motors and wound rotor induction motors according to the structure of the rotor.
5. Motors can be divided into high-speed motors, low-speed motors, constant-speed motors, and speed-regulating motors according to their operating speed.
