This paper proposes a method to minimize the cogging torque and torque r ipple of an interior permanent magnet synchronous motor by adopting asymmetric barrier design and inverting lamination met hod. The analysis method for cogging torque and torque ripple is suggested using finite-element method. An asymmetric barrier i n a permanent magnet rotor is optimally designed without permanent magnet skew. This proposed design for low cogging torque and t orque ripple has an advantage over skew design from a manufacturing point of view. The proposed model is compared with the s kew model and nonskew model by calculating torque characteristics to determine the more effective method to reduce torque distortion.
