Abstract:
Soft magnetic composite (SMC) materials are especially suitable for construction of low-cost high-performance motors with
three-dimensional (3-D) magnetic fields. The 3-D finite-element analysis (FEA) conducted in the design of a claw pole transverse flux
motor (CPTFM) with an SMC core reveals very complicated (flux density) loci in the core when the motor rotates. In order to understand
and account for the effects of the patterns of loci on motor parameters and performance such as core losses, a 3-D magnetic
property testing system was built for magnetic measurement on a cubic SMC sample. 3-D rotational core loss models in SMC materials
and rotating motors are developed.
