Parameter Computation and Performance Prediction of a Claw Pole/Transverse Flux Motor with Soft Magnetic Composite Core

This paper presents the parameter computation and performance prediction of a flux- concentration claw pole/transverse flux motor with soft magnetic composite (SMC) core by using magnetic field finite element analysis and equivalent electrical circuit techniques. The magnetic field distribution in the motor is really complicated, and hence three-dimensional (3D) magnetic field finite element analysis is conducted for accurately determining the key motor parameters such as winding flux, back electromotive force, winding inductance, and core loss. To predict the motor performance, an equivalent electrical circuit is derived. The computation and analysis techniques used in the paper are also helpful for developing other novel machines with new structures and new materials.
