Reduction of Cogging Torque in Permanent Magnet Motors

Journal of the Magnetics Society of Japan, 2007
EPS (Electric Power Steering) enables an increase in automotive fuel efficiency by 3-5% and contributes to the protection of the environment by eliminating the oil medium used in conventional hydraulic power steering. For this reason a sharp increase in demand for EPS is expected.
