Power Capability and Flux-Weakening Performance of Interior Permanent Magnet Synchronous Motor With Multiple Flux Barriers

The paper presents a comparison of electromagnetic torque, output power capability and flux-weakening performance of interior permanent magnet synchronous motor with flux barriers (IPMSMFB) with performances of conventional interior permanent magnet synchronous motor (IPMSM). The calculated performance of conventional IPMSM was confirmed with the measurements in the range of speed 3000-10000 rpm
