TY - CHAP U1 - Konferenzveröffentlichung A1 - Grafmüller, Jan Oliver A1 - Zhang, Julia A1 - Nuß, Uwe T1 - Asymmetric Stator Teeth for Torque Ripple Reduction of Permanent Magnet Synchronous Machines for Hybrid Electric Vehicles T2 - 2014 IEEE International Electric Vehicle Conference N2 - This paper investigates the maximum torque capability and torque ripple reduction using the asymmetric stator teeth for interior permanence magnet (IPM) synchronous machines. Traditional electric machines have the identical width for all stator teeth and the winding function is fixed. Using different widths for different stator teeth changes the winding function, therefore, the torque ripple components. The mathematical modeling of interior permanent magnet (IPM) synchronous machine torque ripple and finite element analysis simulation results for the characteristic properties of electric machines are presented. Compared with a similar rating IPM machine, certain combinations of the teeth widths can reduce the torque ripple by 80% with less than 4% average torque decline.
