Fault-Tolerant Interior-Permanent-Magnet Machines for Hybrid Electric Vehicle Applications
As fault tolerance for interior permanent magnet (IPM) motors is necessary for optimization, the ability of design to accommodate for high torque pulsation is critical for applications of IPM for hybrid electric vehicles (HEV). Researchers here propose a means of reducing such pulsation using a combination of winding distribution, using the appropriate number of slots of the system, and increasing the phase number. Improving back electromotive force (EMF) is achieved through the modification of the winding distribution, which has to be adjusted as increasing the phase number will simultaneously increase the frequency of torque pulsation. Analyzing this system using finite-element analysis (FEA), it was shown that the proposed method of fractional-slot five phase IPM motor configuration was fault resistant as anticipated.
