According to the structure and working principle, it can be divided into DC motor, asynchronous motor and synchronous motor. 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 shielded pole asynchronous motors. AC commutator motor is divided into single-phase series motor, AC -DC dual-purpose motor and repulsion motor. According to the structure and working principle, DC motors can be divided into brushless DC motors and brushed DC motors. Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors can be divided into series DC motors, parallel DC motors, separately excited DC motors and composite DC motors. Permanent magnet DC motors are divided into rare earth permanent magnet DC motors, ferrite permanent magnet DC motors and Al-Ni-Co permanent magnet DC motors.
According to the starting and running modes, it can be divided into capacitor-started single-phase asynchronous motor, capacitor-operated single-phase asynchronous motor, capacitor-started single-phase asynchronous motor and split-phase single-phase asynchronous motor.
Classification by use: it can be divided into drive motor and control motor. The driving motor is divided into electric tools (including drilling, grinding, polishing, slotting, cutting, reaming and other tools) and household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD players, vacuum cleaners, cameras, hair dryers, electric shavers and so on). ) and other general small mechanical equipment (including all kinds of small machine tools, small machinery, medical instruments and electronic instruments).
