ABSTRACT:
A DC electric machine interpole disposed between adjacent main field poles is magnetically isolated from the machine frame and is characterized in that the pole piece or pieces which conduct interpole flux from the interpole into the armature is (are) longitudinally displaced and circumferentially adjacent to the pole piece or pieces which conduct interpole flux from the armature to the interpole. The longitudinal displacement of the sending and receiving pole pieces permits the circumferential width of the interpole to be relatively small thereby reducing flux leakage from main field pole to main field pole to effect an improvement in the performance of the machine.
