Abstract

In this paper, two emerging outer-rotor stator-permanent-magnet (PM) brushless motor drives, namely the doubly-salient PM motor drive and the PM hybrid brushless motor drive, are firstly quantitatively compared, which are particularly attractive for serving as in-wheel motor drives for electric vehicles. In order to enable a fair comparison, these two motor drives are designed with the same peripheral dimensions and based on the same outer-rotor 36/24-pole topology. By utilizing the circuit-field-torque time-stepping finite element method for analysis, their steady-state and transient performances are critically compared. Moreover, the cost analysis of these two machines is conducted to evaluate their cost effectiveness.
