Product classification of electric motors

1. According to the working power classification, it can be divided into DC motor and AC motor according to the different working power of the motor. Among them, the AC motor is also divided into a single-phase motor and a three-phase motor.

2. According to the structure and working principle, the motor can be divided into DC motor, asynchronous motor and synchronous motor according to the structure and working principle. Synchronous motors can also be classified into permanent magnet synchronous motors, reluctance synchronous motors, and hysteresis motors. Asynchronous motors can be divided into induction motors and AC commutator motors. Induction motors are further divided into three-phase asynchronous motors, single-phase asynchronous motors, and shrouded asynchronous motors. The AC commutator motor is further divided into a single-phase series-excited motor, an AC-DC dual-purpose motor, and a repeller motor.

3. According to the starting and running modes, the motor can be divided into a capacitor-starting single-phase asynchronous motor, a capacitor-operated single-phase asynchronous motor, a capacitor-starting single-phase asynchronous motor, and a split-phase single-phase asynchronous motor according to the starting and running modes.

4. According to the purpose, the motor can be divided into a drive motor and a control motor according to the use. The drive motor is divided into electric tools (including drilling, polishing, polishing, slotting, cutting, reaming, etc.) with electric motors and household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVDs). Motors, vacuum cleaners, cameras, hair dryers, electric shavers, etc.) Motors for motors and other general purpose small mechanical equipment (including various small machine tools, small machines, medical equipment, electronic equipment, etc.). The control motor is further divided into a stepping motor and a servo motor.

5. According to the structure of the rotor, the motor can be divided into a cage type induction motor (the old standard is called a squirrel cage type asynchronous motor) and a wound rotor induction motor (the old standard is called a wound type asynchronous motor).

6. According to the operating speed, the motor can be divided into high speed motor, low speed motor, constant speed motor and speed control motor according to the running speed.
