This paper introduces the solution of a 150 kW high speed permanent magnet motor (HSPMM). The motor is studied with its design considerations concluded for high speed application at first; then the HSPMM air gap flux density is analytically calculated and verified by finite element method (FEM); the motor stator slot number and slot opening width are studied and investigated to obtain a desirable...
Permanent magnet synchronous motors (PMSMs) provide a competitive technology for EV traction drives owing to their high power density and high efficiency. In this paper, three types of interior PMSMs with different PM arrangements are modeled by the finite element method (FEM). For a given amount of permanent magnet materials, the V-shape interior PMSM is found better than the U-shape and the conventional...
Because of its unique properties, such as brushless structure, high torque and power density, the claw pole motor will have widely application foreground. This paper introduces a new type of permanent magnet claw pole motor (PMCPM) with outer rotor. The electrical circuit model of this kind of motor have been built, The operation characteristics are simulated by means of powerful simulation software...
