Knowledge of small three-phase asynchronous motor

時間:2016年07月22日 作者:佚名 點擊: 【字體:

Small three-phase asynchronous motor: usually include H80-315MM motor, its output, wide use, in the total load of the grid, its electricity consumption is about 40%. In the early sixties popular for the JO2 series of motors, the series of motor power rating, installation size and the international market, the general standard is different from the motor starting torque is low and the lack of noise control indicators, so now we use the motor For the Y series motor. The motor is rugged, safe and reliable so the use of more and more wide range. However, some users use the motor damage rate of up to 5%, the reason is mostly improper selection, the use of inappropriate, poor protection of the reason. Therefore, the main purpose of this lecture is: to find the quality of the use of motor problems, a proper solution.

       

Small asynchronous motor system
Small asynchronous motors can be divided into: basic series, derived series and dedicated series.
The basic series ---- use a wide range, production capacity, is a general-purpose motor, such as Y series (IP44) small three-phase asynchronous motor.
Derived series ---- in accordance with the different requirements, in the basic series on the basis of a partial change, and other components and the basic series has a high degree of versatility and a certain degree of unity. Derived series of electrical derivation (such as high efficiency motor, YX series), structure derived (such as winding rotor motor YR series), special environment derived (flameproof motor, YB series) and several.
Special series ----- different from the general use, with special requirements and special protection conditions, such as YZ, YZR metallurgy and lifting asynchronous motor.
