In this paper, a type interior permanent magnet (IPM) motor designs is proposed for E scooter application as spindle motors. An existing permanent magnet motor has maximum speed of 50km/h. In order to improve high speed operation up to 70km/h. An Interior Permanent Magnet (IPM) motor alternatives are designed and optimized in detail with optimal magnetic segment shape. The electromagnetic results of IPM V shape motors are compared with the reference Surface Permanent Magnet (SPM) motor for the same design requirements. Detailed loss analysis is also performed for the desired motor structure at high speeds. A prototype motor is manufactured and initial experimental tests are performed. Detailed comparison between Finite Element Analysis and test data are also presented. It is shown that it is possible to have an optimized IPM motor for such high speed spindle application. This paper will figure out optimal angle of magnetic V shape for maximum torque and minimum torque ripple.
