Abstract: With the appearance of high-performance permanent magnet (PM) materials as well as the development of computer technology and nanotechnology and electricity machine theory, scholars have done a lot of research on the self-starting permanent magnet synchronous motor and have made many achievements. Although the starting permanent magnet synchronous motor has many advantages compared with the induction motor, there are also many problems. Since the self-starting motor needs to realise the self-starting and maintaining the synchronous speed operation, its rotor structure design is more complex. The rotor requires the starting winding and the magnets coexist, so there is 'space competition', especially the small motors with high power density. Nowadays, nano-materials are applied on a motor to improve its electromagnetic performance. In this paper, the electromagnetic performance of a PM motor with different metal nano-material bars is researched by finite element analysis (FEA). In this paper, the electromagnetic performance of a PM motor is researched when the rotor bars are with different sizes metal nano-palladium by FEA. The magnetic field distribution, the dynamic speed and torque variation and the eddy current losses are analysed respectively.

Keywords: permanent magnet materials; performance; synchronous motor; nano-material.
