Improved performances of IPM motors with types of double V and deltamagnets by using high flux density materials

The magnetic material has a big influence on the magnetic flux density in airgap of double V and delta magnets of IPM motors. In this paper, the material of Cobalt Steel-VaCoFlux with a high magnetic flux density is proposed for types of double V and delta magnets in the rotor to improve the efficiency of IPM motor.
