ICEMS2017 Keynote Presentation

 

Current Developments and Trends in Permanent Magnet Machines and Drives

 

Abstract:

This keynote speech will start with different stator and rotor topologies of permanent magnet machines for various applications, with emphasis on electric vehicle applications, the current developments and trends will be highlighted, together with worked examples, including

       High torque/High torque density

       High power/High power density

       High speed

       Direct drive

       High efficiency

       High reliability

       High fault tolerance

       High manufacturability

       High system performance

       Low cost

       Low noise and vibration

       High integration, such as materials/power electronics/machines/controllers, as well as system integration and design consideration

Others examples include successful applications of sensorless control and direct torque control.

Finally, two latest examples will be illustrated, i.e. (a) many recently developed novel doubly salient permanent magnet, wound field, and hybrid excited machines with enhanced torque and efficiency, and reduced noise and vibration; (b) many airgap field modulated machines, such as magnetically geared machines, Vernier machines, stator PM machines, and partitioned stator machines.
