Motor Description

• This series of motor are mainly applied in less dust indoor environment where altitude is not exceed 1000m, ambient temperature not exceed 40℃ which is free from steam, corrosive gases of acid and alkali, and monthly average air humidity ≤90% (If temperature is 25℃). This series of motor allows full-voltage direct start. It can adopt reduced-voltage starting if full-voltage starting is not allowed by user power grid, hence, the starting current and terminal voltage decrease in direct proportion and starting torque and terminal voltage decrease in inverse proportion. 

  This series of motor has characteristics of large torque, constant speed and it can remain constant synchronous speed when load changes dramatically. This series of motor mainly applies in mechanical equipment of lower drive speed and large power among mine and cement industries, such as grate ball mill, rod mill, coal mill, etc.
