Permanent Magnet Motor Topologies – Selection Criteria and Considerations
David Coulson, Principal Electromagnetics Engineer, Celera Motion

 

There are multiple options for selecting permanent magnet motor topologies and it can sometimes be difficult to understand the benefits of one topology over another. This presentation will describe the leading available radial PM motor topologies, what their main benefits are, and how they can be best aligned to specific applications. The main focus will be on frameless motor applications including the following topologies:  surface mount permanent magnet motors, synchronous reluctance permanent magnet assist motors, Slotless motors, and IPM motors.
