The Optimal Design of Fractional-slot SPM to Reduce Cogging Torque and Vibration Cho, Gyu-Won; Jang, Woo-Sung; Jang, Ki-Bong; Kim, Gyu-Tak;
This paper deals with the analysis of vibration and noise sources in a modular-type SPM fractional-slot motor. To reduce cogging torque, torque ripple and unequal radial force, which are the main causes of the electromagnetic vibration, the optimal shape of notch and magnet are designed.
