Classification of three-phase asynchronous motor

    1, according to the three-phase asynchronous motor rotor structure

    Can be divided into squirrel-cage motors and wound motor.

    2, according to the three-phase asynchronous motor protection type

    Can be divided into open type (IP11) three-phase asynchronous motors, protective three-phase asynchronous motors (IP22 and IP23) enclosed three-phase asynchronous motors (IP44), explosion-proof three-phase asynchronous motor.

    Open type (IP11): the price is cheap, best cooling conditions, since the rotor and the winding is exposed to the air, can only be used for drying, little dust nor corrosive and explosive gas environment.

    Protection (IP22 and IP23): ventilation conditions are better, to prevent water droplets, iron and other outside debris falling into the interior of the motor, applies only to the drier and small dust nor corrosive and explosive gas environment.

    Closed (IP44): suitable for wet, dusty, vulnerable to wind and rain erosion, corrosive gases, such as poor working conditions, the most common application.

    3, according to the three-phase asynchronous motor ventilation cooling method

    Can be divided into self-cooled three-phase asynchronous motors, fan-cooled three-phase asynchronous motors, fan-cooled three-phase asynchronous motor, pipe-ventilated three-phase asynchronous motor.

    4, according to the three-phase asynchronous motor mounting structure

    Can be divided into horizontal three-phase asynchronous motors, vertical three-phase asynchronous motor with foot three-phase asynchronous motor, flanged three-phase asynchronous motor.

    5, three-phase asynchronous motor insulation class

    Can be divided into the E-Class, B, F, H three-phase asynchronous motor.

    6, quota of work

    Can be divided into continuous three-phase asynchronous motors, intermittent phase asynchronous motors, intermittent three-phase asynchronous motor.
