Review of Design and Performance of Permanent Magnet Synchronous Motor

Permanent magnet synchronous motor(PMSM) is a exceedingly efficient motor and is successfully operated in a wide range of speed. Various types of permanent magnet synchronous motors are accessible in the market offering advantages of direct on line starting as induction motor and effectively running on synchronous speed. Major disadvantages of PMSM is uncertainty of successfully synchronization, loading capability during asynchronous as well as synchronous period. The present market potential for motors places a high value of operating efficiency , reliability, variable speed operation, low running temperature, quiet operation and minimum cost. In comparison to induction motor , PMSM provides the peculiarity of consumer prerequisite along with high power density and high power factor. The advancement in the design technologies and magnetic material allows the achievement of souk ambition at even higher temperature without much more permanent magnetization loss. This paper presented the investigations of new structures appearing in scientific literature carried out by the researchers to obtain multi-objective optimal design for PMSM.
