Motors can be divided according to their function of drive motors and control motors; energy type is divided into DC motors and AC motors; from the speed of the motor in relation to the relationship between the power grid power frequency is divided into synchronous motors and asynchronous motors of the category, according to the number of power supply relative to the classification can be divided into single-phase motors and three-phase motors; type of protection can be divided into Open protection, closed, explosion-proof, waterproof, submersible, according to the installation structure type can be divided into horizontal, vertical, with foot, flange connection, can be divided into E-class, B-class, F-class, H-class insulation level.
Or
1. working power, on the different power of the motor, can be divided into DC motor and AC motor. Including AC motors are also divided into single-phase motors and three-phase motors.
2. Motor structure and working principle, structure and working principle classification, can be divided into asynchronous motor and synchronous motor.
Permanent magnet synchronous motors, synchronous reluctance motors and hysteresis synchronous motors can also be classified as the same.
Asynchronous motors can be classified as induction motors and AC rectifier motors. The induction motors are divided into three-phase asynchronous motors, single-phase induction motors and asynchronous motors for cover. AC commutator motors are subdivided into single-phase series-excited motors, AC and DC motors and push-repulsion motors.
Brushless DC motors and DC brush motors according to the structure and working principle, can be divided into DC motors. Brushed DC motors can be divided into permanent magnet DC motors and electromagnetic DC motors. Electromagnetic DC motors are divided into a series of winding DC motors, and other excitation DC motors, DC motors of excitation DC motors and compound excitation. The permanent magnet DC motors are divided into rare earth permanent magnet DC motors, ferrite permanent magnet DC motors and alnico permanent magnet DC motors.
3. Motor start and operation mode can be categorized into capacitor start type motor start and operation mode, motor capacitor capacitor starting motor and split-phase motor.
4. The use can be divided into the use of motor-driven motors and motor control.
Divided into tools (including drilling, polishing, buffing, slotting, cutting, reaming and other tools) motors, home appliances (including washing machines, electric fans, refrigerators, air conditioners, tape drive motors tape recorders, VCRs, DVD players, vacuum cleaners, cameras, hairdryers, electric shavers, etc.) motors, electric motors, and other general-purpose small machinery and equipment (including a variety of small tools, small machines, medical equipment, electronic equipment, etc.). medical equipment, electronic equipment, etc.).
Divided into stepper motors and servo motors to control the motor.
5. The rotor structure can be divided into structural classification of motor rotor induction motor (the old standard called squirrel cage asynchronous motor) and wire-wound rotor asynchronous motor (the old standard called wire-wound asynchronous motor).
6. motor running speed of the running speed of the classification can be divided into high-speed motors, low-speed motors, constant-speed motors, variable-speed motors.
Divided into low-speed motors, gear motors, electromagnetic speed motors speed reduction torque motors, claw pole synchronous motors.
Speed motors can be divided into step constant speed motors, constant speed motors stepless speed regulation of step speed motor stepless speed motor, electromagnetic speed motor, DC variable speed motor PWM frequency conversion speed motor and switch can be divided into reluctance motor.
