Stator of synchronous machine
WebPower electronic converters can operate the stator of synchronous or asynchronous machines. In other applications, the power converter can be connected to the rotor of a wound rotor induction machine. In the first case, the converter handles the overall power of the machine and it operates in a wide speed range. WebSTATOR MAGNET ROTOR CORE Fig. 1. Structure of the permanent magnet synchronous machine [3] The stator carries a three-phase winding, which produces a near sinusoidal distribution of magneto motive force based on the value of the stator current. The magnets are mounted on the surface of the motor core. They have the same role as the I
