Motor Classification

1. Classified according to the power supply
Work according to motor power can be divided into BLDC motor driver and AC motor. Which is also divided into single-phase AC motors and three phase motor electric motor.
2. According to the structure and working principle of classification
According to the motor according to the different structure and working principle can be divided into direct current motor, asynchronous motor and bike motor kit. bike motor kit can also be divided into permanent bike motor kit, magnetic resistance bike motor kit and hysteresis bike motor kit. Induction motors and AC induction motors can be divided into commutator motor. Is divided into three-phase induction motor asynchronous motor, single phase induction motor and shaded pole asynchronous motors. AC commutator motor is divided into single-phase series motor, AC and DC motors and repulsion motor. DC motor according to the structure and working principle of brushless DC motor and can be divided into brush DC motor. Brush DC motors can be divided into permanent magnet DC motor DC motor and solenoid. Electromagnetic DC motor is divided into series excited DC motor, and excited DC motor, and re-excited DC motor excited DC motor. Permanent magnet DC motor is divided into rare earth permanent magnet DC motor, ferrite permanent magnet DC motor and Alnico permanent magnet DC motor.
3. Starting with the operation mode according to classification
According to press start and run motors in different ways, can be divided into single-phase capacitor start asynchronous motor, capacitor-run single-phase asynchronous motor, capacitor start single phase induction motor operation and sub-phase single-phase asynchronous motor.
4. Use classification
Can be divided into motor and control for driving motors. Electric drive motors are divided into tools (including drilling, polishing, grinding, grooving, cutting, reaming and other tools) with the motor, household appliances (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, DVD machines, vacuum cleaners, cameras, hair dryers, electric razors, etc.) with small motors and other general-purpose machinery and equipment (including a variety of small tools, small machinery, medical equipment, electronic equipment, etc.) electric motor. Controlling the motor is divided into stepper motor and servo motors.
5. Classified according to the structure of the rotor
According to the structure of the motor at different rotor can be divided into the cage induction motor (the old standard called the squirrel cage induction motor) and wound-rotor induction motor (the old standard called the winding induction motor).
6. Classified according to running speed
According to operate the motor at different speeds, can be divided into high-speed motor, low speed motors, constant speed motors, variable speed motor. Low-speed motor is divided into gear motors, electromagnetic gear motors, torque motors and claw bike motor kit and so on. Speed ​​motor in addition to constant speed motors can be divided into a class, no class constant speed motor, a variable speed motor and variable speed motors, it can also be divided into electromagnetic motor, DC motor speed control, PWM inverter and motor Switched Reluctance Motor. Induction motor rotor speed is always slightly lower than the rotating magnetic field of the synchronous speed. bike motor kit rotor speed and the load is independent and always remain synchronous speed.
