1000 hp,synchronous motor. 2004-6-16i have a synchronous motor coupled to a ball mill by clutch it starts uncoupled and after it synchronizes the clutch engages the load nameplate and other data and
Synchronous machines can be found wherever there is a demand for highly efficient, cost-effective, dependable machines. They are frequently used for rolling, ball and sag mills, chippers, mixers, pulp refiners, pumps, fans, and compressor (reprocating and centrifical) drives.
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
DC Current Excited Motor Applications of Synchronous Motors. usually, synchronous motors are used for applications where precise and constant speed is required. Low power applications of these motors include positioning machines. These are also applied in robot actuators.Ball mills, clocks, record player turntables also make use of synchronous motors.
Variable Speed . Single or double pinion driving systems. Designed to drive and control the speed of the medium voltage motors coupled to the SAG/AG, ball and HPGR mills with single or double pinion, the MVW01 frequency drive uses state of the art technology through a multilevel structure with medium voltage IGBTs, reducing the harmonic currents on the motor
The drive configuration for this project known as SBRS (Start Ball, Run SAG) meaning that the VSD is to soft- start with frozen charge detection the ball mill, run up to nominal speed, smoothly connect ball mill to the grid so that the ball mill is operating with fixed speed, then soft- start with frozen charge detection the SAG mill
