摘　　要：Due to high torque density and efficiency,permanent magnet machines have been used for many applications,ranging from domestic appliance,industrial automation,robot,electric vehicle,to wind power generation etc.Various novel permanent magnet machine topologies have been developed and many new topologies are still emerging,whilst many novel control strategies are being developed.On the other hand,magnetless machines,including induction,switched and synchronous reluctance,and wound-field synchronous machines,can eliminate the use of expensive rare-earth magnets and their design,analysis and control are currently under extensive investigation.
