PROJECT TITLE :

Design and Verification of 150-krpm PMSM Based on Experiment Results of Prototype

ABSTRACT:

This paper proposes the design method of a 2.sixty two-kW a hundred and fifty-krpm high-speed surface-mounted permanent-magnet synchronous motor. To fulfill the desired specifications, the numbers of poles and slots were determined by considering the utmost speed and also the rotary stability plagued by the vibration of the rotor. Additionally, this paper describes not solely the appropriate material selection technique however conjointly the appropriate geometry style technique based on analytic approaches. Furthermore, to precisely evaluate the bearing and windage losses at a high speed, a technique that combines the finite-part method and also the experiment results of the prototype was used. Thus, an improved motor was designed, which had higher most power and speed than the prototype and a lower mass moment of inertia. Finally, tests were conducted to verify the validity of the proposed style method and also the effectiveness of the motor.
