Owing to their high efficiency and power density, high-speed permanent magnet (PM) brushless machines are emerging as a key technology for applications as varied as spindle drives, centrifugal compressors, turbo-molecular pumps, gas-turbine generator units, and electric/hybrid vehicle traction systems [1].
Recently, high-speed centrifugal turbo-compressors have been under intensive research and development. Since, compared to conventional compressors, high-speed centrifugal compressors have numerous qualities such as simple structure, light weight, small size, and high efficiency, etc. In order to maintain the mechanical integrity of a high-speed permanent magnet (PM) machine rotor intended for high-speed...
Switched reluctance motor (SRM) has simple structure with a winding only on the stator and not on the rotor. The costs are lower than other motors due to its simple construction. It is easy to implement a high speed drive system and both the torque and efficiency of the unit volume are highly superior to all others. The simplest excitation strategy for the SRM is generally described by three excitation...
