The gearless drive design was not applied to the mills in the mineral industry until 1981 when the thenworld''s largest ball mill, m diameter and m long driven by a MW motor, was installed at Sydvaranger in Norway (Meintrup and Kleiner, 1982).
In the world of mining and milling the "electrical term" LSSM stands for "Low Speed Synchronous Motor" and usually means a mill where the motor rated speed is in the range of 10 RPM, the same speed as the mill turns. A high speed motor can run at 900 RPM and uses a gearbox to turn down the speed. A medium speed motor runs in the range of 100 RPM and uses the gear ratio of the pinion ...

Synchronous Motor. The synchronous motor doesn''t rely on induction current for working. In these motors, unlike induction motor, multiphase AC electromagnets are present on the stator, which produces a rotating magnetic rotor is of a permanent magnet which gets synced with the rotating magnetic field and rotates in synchronous to the frequency of current applied to it.
· This video shows soft start of full loaded Ball Mill. The Mill rotated by 900 kW (6kV) synchronous motor STDM which fed from MV (Medium Voltage) thyristor Variable Frequency Drive (VFD).
Main drives are predominantly closedloop controlled, electric synchronous, and asynchronous motors. Their applications include kit or housed motors for use in turning, milling and grinding machines as well as in machining centers. The traditional spindle drives with housed motors – mostly aircooled – are also popular as main drives. In comparison with motor spindles they are less costly ...

· We have an 1200 HP Synchronous motor with brushes. We have been experiencing exciter problems quite often when we have to restart or after a disturbance within our mill. The current problem we are experiencing is the mill was offline due to low tonnage through the mill, it was taken down normally. When we went to restart, it tripped in locked rotor current, we confirmed the current by .

The induction motor drive has many applications like it is used in fans, blowers, mill runout tables, cranes conveyers, traction, etc. The induction motor drive is selfstarting, or we can say when the supply is given to the motor, it starts rotating without any external supply.
Mill application features. Frozen charge protection – Detects frozen charge in the mill, minimizing equipment wear and liner replacements.; Coupling supervision – Detects if a failure or slippage occurs in the couplings and stops the system in case, preventing major damages.; Standstill detection – Prevents the motors from restarting if the mill is still rocking or moving after a stop ...

The site is Latin America''s largest ball mill operation. Grupo Mexico will use GE''s advanced synchronous motor technology to add 84 megawatts (MW) of power at six Buenavista ball mills.
Synchronous machines can be found wherever there is a demand for highly efficient, costeffective, dependable machines. They are frequently used for rolling, ball and sag mills, chippers, mixers, pulp refiners, pumps, fans, and compressor (reprocating and centrifical) drives.
Type. Synchronous motors fall under the more general category of synchronous machines which also includes the synchronous action will be observed if the field poles are "driven ead of the resultant airgap flux by the forward motion of the prime mover". Motor action will be observed if the field poles are "dragged behind the resultant airgap flux by the retarding torque ...
