Abstract :
This paper presents a three-phase claw pole permanent magnet soft magnetic composite motor, which was designed to take advantage of specific properties of the material. Parameter calculations by the finite element magnetic field analysis and performance prediction by the equivalent circuit are discussed. To verify the theory, a prototype motor was constructed and operated by a sensorless brushless dc drive scheme. The experiment results are reported and show good correlation with the theory.
