ball mill in variable speed synchronous motor

Milling - Energy intensive and high maintenanceA squirrel-cage motor or a synchronous motor started direct on line without any help of a frequency converter normally cannot produce sufficient starting torque. Therefore it is required to accelerate the mill without load until the rated speed and then, by means ofSynchronous Motors - Electric machineSynchronous motors can operate at leading power factors, providing VARs to the power system, reducing demand charges often caused by induction motors. Constant Speed Synchronous motor speed is unaffected by line or load conditions, providing greater

Detailed introduction

Increasing availability through advanced Gearless Drive .Speed adjustment to worn liners results in optimized throughput and less wear of grinding media as cited by a representative of a German mill supplier representative. Ball mill speed can be reduced during short maintenance measures, e.g. inspections ofLarge Ball Mill Synchronous Motor - Made-in-ChinaSynchronous Motor, Ball Mill Motor, 1250kw Synchronous Motor manufacturer / supplier in China, offering Large Ball Mill Synchronous Motor, AC Induction Motor Electric Llift Motor, AC Induction Motor High Temperature Electric Motors and so on.

Synchronous motor supply to load at a constant speed or rate. The steady state speed of the motor is constant from no load to the maximum torque that the motor can supply (called as pull out torque).Synchronous motor - WikipediaSince a synchronous motor produces no inherent average torque at standstill, it cannot accelerate to synchronous speed without some supplemental mechanism. [2] Large motors operating on commercial power frequency include a squirrel-cage induction winding which provides sufficient torque for acceleration and which also serves to damp oscillations in motor speed in operation.
