Abstract

An interior permanent magnet synchronous motor experiences large harmonic iron loss in the stator teeth caused by the harmonic magnetomotive forces. In particular, the eddy current loss remarkably increases at high rotational speeds under the flux weakening control. In this paper, a novel suppression control method for the stator iron loss is proposed by utilizing the individual winding current control. Although the proposed method requires multi-phase winding and multiple full-bridge inverters, the individual winding current control can observe and regulate the flux density in each tooth. This paper reveals that the proposed control method can achieve the extensive reduction of the total iron loss.
