Abstract :
This paper presents a comparative study of two types of low cost single-phase wound-field switched flux machines with DC field and AC armature windings having the same coil-pitch of 2 slot-pitches and having different coil-pitches of 1 and 3 slot-pitches, respectively. Both can share the same stator lamination but the later can have shorter end-windings and lower iron loss for the 12-slot/6-pole configuration. The performance, including back-EMF, cogging torque, and static torque, of both machines are analysed and compared by two-dimensional (2-D) finite element analysis (FEA) and validated by experiments on the prototype machines.
