Rotor design and control method of synchronous reluctance motor with multiflux barrier

To design the rotor of a synchronous reluctance motor with multiple flux barriers, the studies of the number of barriers, bridge width and other elements are important. It is found that a 6-layer configuration is best in terms of efficiency. In performance tests, a prototype efficiency is 6[%] higher than a conventional inverter-driven induction motor. The rotor also rotate at speeds in excess of 10,000 [r/min] because magnetic and nonmagnetic parts were built into a single body made of alloy.
