Two-Slot Coil Pitch For Five-Phase Integrated Permanent Magnet Synchronous Machine

Edité par HAL CCSD ; IEEE

International audience. This paper presents a simple method to size a concentrated winding permament magnet synchronous machine when a high number of slots is needed. A classical concentrated winding machine leads to a number of pole pairs close to the number of slots to be efficient. Thanks to a two slots pitches winding, number of slots can be doubled without deteriorate the winding factor. Moreover, this specific winding is also useful to deal with embarassing magnetomotive force harmonics. The method is detailed here for a specific case of a machine with integrated power converter. Sizing of the machine is also presented and finite element simulations results show performances of this design compared to a conventional one.
