Abstract: The performances of two topologies of low-speed double-fed brushless machine (DFBM) with fractional slot windings are quantitatively compared and analyzed using two-dimensional (2-D) finite element method (FEM). To fairly compare the torque capability and power efficiency of different DFBMs, the investigated DFBMs have the same outer diameter, the same axial stack length and the same iron core materials, and some comparison rules are presented. In order to maximize the torque density, several important structure parameters are optimized. The results of this paper reveal the torque density levels and power density levels of two kinds of DFBMs.
