Motor is widely used, various kinds of. We usually is based on the motor classification to distinguish between motor applied to the transaction. Motorwith classification as follows:

1 types according to the working power supply division: divided into DCmotor and AC motor.

DC motor according to the structure and working principle can be divided into: brushless DC motor and brushless DC motor.

DC motor with a brush can be divided into: permanent magnet DC motor and electromagnetic DC motor.

Electromagnetic DC Motor Division: series wound DC motor, DC shuntmotor, he excited DC motor and the compound wound DC motor.

Division of permanent magnetic DC motor: iron oxide of rare-earth permanent magnet DC motor, permanent magnet DC motor and Al Ni Gu Yongci DC motor.

The AC motor also can be divided into: single phase motor and the three-phase motor.

According to the structure and working principle of the 2 division: can be divided into DC motor, induction motor, synchronous motor.

Synchronous motor can be divided into: permanent magnet synchronous motor, reluctance synchronous motor and magnetic hysteresis synchronous motor.

Asynchronous motor can be divided into: induction motor and ACcommutator motor.

Induction motor can be divided into: three-phase asynchronous motor,single-phase asynchronous motor and shaded pole asynchronous motoretc..

Commutator motor can be divided into: single phase series motor, AC and DC motor and repulsion motor.

3 according to the starting and operating mode classification: capacitor startcapacitor type single-phase asynchronous motor, running capacitor type single-phase asynchronous motor, the starting operation of single-phase asynchronous motor and phase splitting single-phase asynchronous motor.

4 divided by purpose: the drive motor and control motor.

Drive motor division: electric tools (including drilling, polishing, polishing,slotting, cutting and reaming tools such as) with motor, appliance (including washing machines, electric fans, refrigerators, air conditioners, tape recorders, video recorders, video machines, vacuum cleaners, cameras,hair dryer, electric razor) motor and other general small machinery and equipment (including a variety of small tools, small machinery, medical equipment, electronic equipment and so on) motor.

Motor control is divided: stepping motor and servo motor etc..

Divided by the structure: 5 of the rotor cage induction motor (the old standard called the squirrel cage asynchronous motor) and wound rotor induction motor (the old standard called the winding asynchronous motor).

According to the running speed of 6 division: high speed motor, low speed motor, constant speed motor, adjustable speed motor. Low speed motor is divided into gear motor, gear motor, the electromagnetic torque motor andclaw pole synchronous motor.

Variable speed motor in addition to can be divided into constant speedmotor, and stepless constant speed motor, step speed motor and a stepless speed changing motor, but also can be divided into electromagnetic adjustable speed motor, DC speed regulating motor, PWM frequency conversion motor and switched reluctance motor.

Synchronous speed rotor speed of asynchronous motor is always slightly below the rotating magnetic field.

Synchronous motor rotor speed and load size independent and always keep the synchronous speed.
