SYNCHRONIZATION PROBLEM OF HIGH-PERFORMANCE RELUCTANCE MOTORS

The paper reports an investigation of the synchronisation problem of t hree phase high performance reluctance motors, This problem stems from the fact that these motors can have extremely high reactance ratio an d hence a significant pull-out torque. While this is a welcomed proper ty from a steady state stability point of view, it can make the proces s of synchronisation a difficult task. To carry out this investigation a rigorous state space model in the original phase values reference f rame was developed and simulated. The developed model takes into consi deration the effect of torsional dynamics. This is augmented by a stea dy state analysis based on Park's two-axis reference frame.
