摘要

Using magnetic flux barriers in the stator yoke of electric machines with fractional slots, tooth-concentrated winding, it is possible to reduce or even to cancel some space harmonics of low-order in the air-gap flux density resulting in lower rotor losses induced by the armature reaction field. A novel interior permanent magnet synchronous machine (IPMSM) is designed using this new technique [1]. In this paper losses of this new machine are analyzed and compared with conventional 12-teeth/10-poles concentrated windings IPMSMs. With this new design, losses of this IPMSM resulting from high-frequency (HF) injection for sensorless control are reduced compared with the conventional ones.
