May 08, 2017 Thus the power to drive the whole mill. = 49.5 + 66.0 = 115.5 h.p. = 86 kW. From the published data, the measured power to the motor terminals is 103 kW, and so the power demand of 86 kW by the mill leads to a combined efficiency of motor and transmission of 83%, which is reasonable.

ETAP Motor Starting Study for 600kW Ball Mill Electric

ETAP Motor Starting Study for 600kW Ball Mill Electric

Jun 27, 2020 RE: ETAP Motor Starting Study for 600kW Ball Mill. LionelHutz (Electrical) 7 Jul 20 12:23. The problem with ball mills vs a simulation like ETAP is that the mill initially is a torque load that is dependent on rotation angle until the charge start to tumble. ETAP only simulates the torque vs speed as a curve.

Synchronous motor Wikipedia

Synchronous motor Wikipedia

A synchronous electric motor is an AC motor in which, at steady state, the rotation of the shaft is synchronized with the frequency of the supply current; the rotation period is exactly equal to an integral number of AC cycles. Synchronous motors contain multiphase AC electromagnets on the stator of the motor that create a magnetic field which rotates in time with the oscillations of the line ...
