The Relationship between PM Synchronous Motor and Permanent Magnet Material function

The superiority and inferiority of PM machine is closely related with the function parameter of permanent magnet material which is being used.This paper analysis the relationship between PM synchronous motor and permanent magnet material function;it also indicates that because permanent magnent material with superior magnent function are used,the function parameter of motor can be greatly improved,thus achieve obvious economic profit.Then this paper explains several aspects which should be considered in the PM synchronous motor design process.Finally it points out the research direction of PM synchronous motor.
