Comparative analysis of Double Stator Switched Reluctance Machine and Permanent Magnet Synchronous machine

High torque density Permanent Magnet machine are widely used in practice. However, the rising cost of high energy rare earth permanent magnet material stimulates the needs for electrical machines using less or no permanent magnet. Double Stator Switched Reluctance Machine is a novel high torque density reluctance machine. This paper provides a comparison between surface mount Permanent Magnet Synchronous Machine and Double Stator Switched Reluctance Machine. Their generated electromagnetic force components are investigated. Torque density and material cost are compared via case study.
