This paper analyzes and compares the synchronous reluctance motor (SynRM) performance for a conventional star winding and for a combined star-delta connected winding under healthy and faulty conditions. The finite element method is used to simulate the SynRM characteristics in case of normal star and in case of combined star-delta connected windings. For the healthy case, it was found that for the...
In the sub-synchronous mode, series-connected wound-rotor induction motor can run at a speed below the synchronous speed with self-starting capability in a manner similar to that of the normal mode of operation of an induction motor. Under proper conditions, operation in the series-connected mode can achieve better characteristics compared with normal induction motor by short-circuiting rotor circuit...
The wound-rotor induction machine is capable of electromechanical energy conversion, if the stator and rotor windings are connected in series with a proper phase sequence. As a motor, the operation can be in one of two modes. In the first mode, the motor runs at exactly twice the synchronous speed for stable loading conditions. In the second mode, the motor runs at a speed below the synchronous speed...
