Cogging Torque Analysis of Thin-Shaped Permanent Motor With Pole-Orientations Taking into Account of Material Properties

Takushi Fujioka,Youichi Tanabe, FUJITSU GENERAL LIMITED


Cogging torques of thin-shaped permanent magnet motor should be greatly influenced by the stator design or orientation of pole-oriented permanent magnet. Now, some material properties of magnets have been taken into account in the calculation of orientation, by which some cogging torques should be different from the results ignoring their properties.
Key Words: Thin-shaped permanent magnet motor, Cogging torque, Material properties, Pole-Oriented permanent magnet
