Flux switching permanent magnet machines provide many advantages. Due to their superior behavior associated with sinusoidal Back-EMF and low torque ripple, topologies featuring 12 stator teeth and 10 rotor poles (12/10) are favored. However, this follows that for a given mechanical rotor speed, the required electric fundamental frequency is ten times to that of a conventional two pole PM machine imposing...
High-speed machines require structurally robust rotor to withstand high centrifugal forces. Flux switching permanent magnet (FSPM) machines are ideal for high speeds since they have a simple and robust rotor structure. They also utilize permanent magnet (PM) in the stator enabling them to achieve high power density. It is desirable to keep the operating frequency minimized to reduce core losses and...
