Classification of ac motor

1,according to the working power supply classification:depending on the motor working power supply,can be divided into direct current motor and ac motor.Which ac motor is also divided into single-phase motor and three-phase motor. single phase generator 2,according to the structure and working principle of classification:motor according to the structure and working principle can be divided into small electric motors asynchronous motor and synchronous motor.Synchronous motor can also be divided into permanent magnet synchronous motor,synchronous motor and magnetic resistance motor with hysteresis.Asynchronous motor can be divided into ac induction motor and motor commutator.Induction motor is divided into three phase asynchronous motor,single-phase asynchronous motor and cover pole asynchronous motor.Communication is divided into single-phase series motor commutator motor,ac/dc motors and repulsion motor. 3,according to the classification of start-up and operation mode:the motor according to the start-up and operation mode can be divided www.dongfeng-motor.com into capacitor start motor,capacitor contributed to motor,capacitor start motor running and split-phase motors. 

4,according to the rotor structure classification:according to the structure of the rotor can be divided into the cage induction motor (old standard called squirrel-cage asynchronous motor) and wound rotor induction motor (wound asynchronous motor is called old standard). 5,according to the speed of classification:can be divided into the high speed motor,motor at low speed,constant speed motor and speed regulating motor.Has general is series of brush type ac motor,commonly used in small electric tools,such as some electric hair dryer,hand electric drill,the vacuum cleaner...Work with electric spark,noise is very big,but small size,large torque.Startup capacitor is used to produce to split phase of electrical motor single-phase ac power supply,using capacitor capacitive reactance of alternating current (ac),and after a coil in series,the overall current phase shift than simple inductor current phase shift,which USES two different phase current,the magnetic field to produce a different time,such as three-phase alternating current (ac),form a rotating magnetic field.
