Modeling and presentation of the series magnetized synchronous machine

Summary, in English

In this paper mathematical modeling and a dedicated control algorithm of the patented Series Magnetized Synchronous Machine (SMSM) are presented. The SMSM is an electrically magnetized synchronous machine, where the field current is supplied via the stator windings and a diode bridge rectifier. For the SMSM there is no need for additional field voltage supply and the SMSM exhibits significantly faster field current dynamics than the Electrically magnetized synchronous machine (EMSM). Other additional benefits that follow are the possibility to utilize passive field weakening and simple sensor-less operation. The SMSM is in this case considered for an automotive application and therefore relates to the operating region of high rotational speed, low voltage and high current. This region of operation is considered to be the most challenging for this type of machine.
