Double three-phase PMSM structures for fail operational control
MetadataZobrazit celý záznam
This paper deals with permanent magnet synchronous motors (PMSM) structures. Especially their double three-phase arrangements are analysed in detail. Comparison of three different structures is treated. Non-overlapping concentrated winding is the first analysed structure. Distributed winding arrangement with interlaced sub-systems and also distributed winding arrangement with segregated sub-systems follows. The behaviour of all motor structures during normal operation is the same but the properties during faults are different. The motor behaviour during active short circuit (ASC) is discussed. ASC of whole motor and also partial ASC tests were performed. Current waveforms in different operating points are compared. Results show differences of individual structures with respect to operation during fault.
