Cogging Torque Reduction Design for CVVT Using Response Surface Methodology
The Transactions of The Korean Institute of Electrical Engineers, 2016 This paper deals with the design process for an outer-rotor-type surface-mounted permanent magnet synchronous motor (SPMSM) used in continuous variable valve timing (CVVT) systems in automobiles with internal combustion engines. When the same size, outer-rotor-type SPMSMs generate larger torque and more stable than inner-rotor-type SPMSMs.
