Synchronous Motor : Working Principle, Types, and

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- field.Here 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.

Advantages of SER drives for SAG mills GoHz

Advantages of the wound rotor/SER drive are: If the SER converter drive fails, the drive can be switched to fixed speed bypass starting the usual way with the LRS. The converter only needs to be sized for 15-20% of the total motor rating with associated reduction in floor space, air-conditioning etc.
