IPM motors produce torque based on two different mechanisms. The first is permanent-magnet torque, which is generated by the flux linkage between the PM rotor field and the electro-magnetic field of the stator. It is the same torque produced by SPM motors. IPM designs produce a second force known as reluctance torque. The shape and location of the slots in the rotor laminations are designed to channel magnetic flux so that even if the slots were left as air gaps, the rotor would experience a force to align the magnetic flux lines with those generated by the stator coils. Because those coils are energized in sequence to create a rotating series of alternating north-south magnetic poles, the rotor will follow that progression, generating reluctance torque and causing it to continually turn. It is now very popular in industrial and military applications (for example, hybrid motors can eliminate the need for driveshaft’s and axles, enabling new configurations that range from improved under-vehicle blast protection in military applications to reductions in overall vehicle height to improve highway fuel economy.) by providing high power density and high efficiency compared to other types of motors. This paper presents the use of finite element method harmonic analysis for investigation of IPM motor acoustics noise.
