Abstract

The design of an axially-laminated interior permanent magnet motor drive optimised for its field-weakening performance is described. A 7.5 kW motor was built based on low-cost, flexible rubber-bonded ferrite magnet sheet. It achieved an extremely wide constant power speed range of greater than 7.5:1, in contrast to the 2.5:1 obtained both with an axially-laminated synchronous reluctance motor and a standard induction motor. The excellent field-weakening performance makes this type of motor a serious contender for applications such as machine-tool main spindle drives and traction
