Abstract: This paper investigated the inductance characteristic of the double stator permanent magnet brushless (DS-PMBL) machine by using two dimensions finite element analysis (FEA), proposed a new numeric calculation method to calculate both unsaturated inductance and saturated inductance of the DS-PMBL motor, and derived the variation tendency of the armature winding inductance. Experimental results verify the FEA and the theoretical analysis by measuring the armature winding inductance of an existing DS-PMBL motor.
