    Mar 29, 2007· The only thing I would add is that the operating losses on a soft start can be eliminated by using a bypass contactor I had one customer use a VFD once on a vertical ball mill because the motor was designed for 50Hz and used in the US at 60Hz, but we had to oversize the VFD by 100% to get enough starting torque from itMay 13, 2018· LINE : ID wisarut007Softstarter motor ball mill 90 kw

    Mill, ball • Mill, hammer • Mill, roller • Using AAC, the soft starter learns your motor’s performance during start and stop, then adjusts control to optimize performance The soft starter estimates the motor’s speed throughout each AAC start and stop, and adjusts power to the motor to provide theFeb 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 stallsCement Mill Soft Start Electric motors & generators

  • The difference between VFD and Soft Starter

    Besides of the motor soft starting, VFD also can control the motor speed, to save energy Cost: VFD's cost may be as high as triple as the soft starter If the motor works at full load all the time (means no need to vary the speed), then soft starter is your selection In other case, say the ball mill works at 80% load, then choose the VFD, the
