| Abstract |
This paper presents the design and performance comparison of high-speed permanent magnet synchronous motors (PMSMs) based on the rotor structure, analyzed through electromagnetic and mechanical methods. Under the same requirements and constraints, the rotor sizes of high-speed PMSMs were selected using torque per rotor volume (TRV) and split ratio according to the structures of surface-mounted permanent magnet and interior permanent magnet rotors. The electromagnetic and mechanical analyses were performed based on finite element analysis, and the electromagnetic analysis results were extensively compared while considering mechanical stability and manufacturability. Based on the comparison of the comprehensive analysis results according to the rotor structures, it can be widely used in the design of high-speed PMSMs for various applications. |
