In the paper the design of an IPMSG for small wind turbines is presented. Based on classical construction of induction motor (IM), the internal permanent magnet generator (IPMG) was projected. Parameterization and sweep analysis of the rotor geometry was done in the finite element analysis (FEA) software, to obtain the maximum back electromotive force (BEMF). Based on this analysis, one case was chosen...
This paper presents a sensorless starting procedure for a soft starter driven IE4 direct on line permanent magnet synchronous motor (PMSM). First, the initial position of the rotor is determined using a pulsating current space vector. Subsequently, the motor is started from standstill by the soft starter from a known position. The following firing sequences are calculated on the basis of the flux...
