Classification Of Three - Phase Asynchronous Motor Used
- Jun 02, 2017 -

Compared with single-phase asynchronous Motor Used, three-phase asynchronous Motor Used running performance, and can save a variety of materials. According to the different structure of the rotor, three-phase asynchronous Motor Used can be divided into two kinds of cage and winding. Cage rotor asynchronous Motor Used structure is simple, reliable, light weight, cheap, has been widely used, the main drawback is difficult to speed. The three-phase windings of the wound three-phase asynchronous Motor Used are also provided with three-phase windings and connected to the external rheostat through a slip ring. Adjusting the varistor resistance can improve the starting performance of the Motor Used and adjust the Motor Used speed. Three-phase asynchronous Motor Used six classification methods:

1, according to the three-phase asynchronous Motor Used rotor structure

Can be divided into squirrel-cage Motor Used and winding Motor Used.

2, according to the three-phase asynchronous Motor Used protection type

Can be divided into open (IP11) three-phase asynchronous Motor Used, protective three-phase asynchronous Motor Used (IP22 and IP23), closed three-phase asynchronous Motor Used (IP44), explosion-proof three-phase asynchronous Motor Used.

Open type (IP11): cheap, the best heat dissipation conditions, because the rotor and winding exposed to the air, can only be used for dry, little dust and no corrosive and explosive gas environment.

Protection (IP22 and IP23): ventilation and cooling conditions are better, to prevent water droplets, iron and other external debris into the Motor Used inside, only for more dry and dusty and no corrosive and explosive gas environment.

Closed (IP44): for wet, dusty, vulnerable to wind and rain erosion, corrosive gases and other harsh working environment, the most common application.

3, according to three-phase asynchronous Motor Used ventilation cooling

Can be divided into self-cooled three-phase asynchronous Motor Used, fan-cooled three-phase asynchronous Motor Used, his fan-cooled three-phase asynchronous Motor Used, pipeline ventilation three-phase asynchronous Motor Used.

4, according to the three-phase asynchronous Motor Used installation structure

Can be divided into horizontal three-phase asynchronous Motor Used, vertical three-phase asynchronous Motor Used, with three-phase asynchronous Motor Used, with three-phase asynchronous Motor Used flange.

5, according to the three-phase asynchronous Motor Used insulation class

Can be divided into E-class, B-class, F-class, H-class three-phase asynchronous Motor Used.

6, according to work quota

Can be divided into continuous three-phase asynchronous Motor Used, intermittent three-phase asynchronous Motor Used, intermittent three-phase asynchronous Motor Used.
