Cogging torque reduction of Interior Permanent Magnet Synchronous Motor (IPMSM) [PDF]
Scientia Iranica, 2017 In this paper using combination of two separated ideas the torque ripple of Interior Permanent Magnet Synchronous Motor (IPMSM) is reduced. These two ideas are rotor PM segmented and modifying the rotor structure based on pole-arc ratio of flux barrier optimization.

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.
