Abstract: For each characteristic of surface-mounted permanent magnet motor and built-in permanent magnet motor, this paper presented a new rotor hybrid topologies structure of both the permanent magnet motors. Surface mounted, built-in and hybrid permanent magnet motor topology model were established using the finite element method for to calculate the static magnetic field three structures of the motor. Comparative analysis of their contour distribution of the pole from the amplitude distribution within the air gap flux density and the flux density of the cloud were done. Air-gap magnetic field distribution in permanent magnet motor proposed new structure is more close to the sine, which is basis on the motor design, operation and so on.
Key words: permanent magnet synchronous motor; surface-mounted PM; built-in PM, hybrid topologies structure; field analysis
