Abstract

This paper presents the results of a new flux switching motor and drive offering high power density and an extremely low cost power electronic controller. The motor contains a DC field winding and a bifilar armature winding, both on the stator with a simple and rugged salient pole reluctance rotor. The power electronic controller requires only two ground referenced power transistors. This delivers electronic commutation, high dynamic performance, speed and torque control at an extremely low cost. The design of the motor and its electronic controller is described and test results of a complete drive delivering 2 kW at 15000 r/min are presented.
