Cement Mill Soft Start Electric motors & generators. Feb 12, 2009 When this happens, we bypass the soft start, and the mill starts right up. Inrush current across the line is in the neighborhood of 1300 amps. We don''t like to do this often, because it leads to increased failure of the stator windings. I would say that the motor stalls.

Because the current of the rotor is very large at this time, the stator current also increases greatly, even up to 4 to 7 times the rated current, which is the reason for the large starting current. Why is the current small after starting: as the motor speed increases, the stator magnetic field cuts the rotor conductor at a reduced speed, the induced potential in the rotor conductor decreases

If the motor is started directly, without starter: The current absorbed by the motor during the start is extremely high. For example, a 110 kW motor with a nominal current of 205 A and a ratio starting current / nominal current equal to 6 absorbs 1230 A during the start. That will fall drastically the voltage in the MV/LV transformer which can
