Cement Mill Soft Start Electric motors & generators

Feb 12, 2009· The motor does not want to make it over the cascade point in soft start mode. 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.

Cycloconverter Wikipedia

This is invaluable with, for example, ball mills, allowing starting with a full load rather than the alternative of having to start the mill with an empty barrel then progressively load it to full capacity. A fully loaded "hard start" for such equipment would essentially be applying full power to a stalled motor.

Control Engineering Current motor starting methods

Oct 05, 2015· The disadvantage of the soft starter technology compared to the frequency converter is that it is unable to control the speed and is unsuitable for applications requiring speed control. When starting loads with high inertial torque, for example in ball mills, it is easily applicable and has to be selected at a higher power level.
