Abstract
A method of fabricating an armature for a motor includes providing a laminated assembly having a length, a central axis, and a plurality of open slots each extending the length and each configured to locate one conductor at a first greater radial distance from the central axis and another conductor at a second lesser radial distance from the central axis. A first conductor is inserted into a first one of the slots at the greater radial distance such that the first conductor extends out of the first one of the slots. A free end of the inserted first conductor is bent in each of a first direction and a second direction orthogonal to the first direction. A second conductor is inserted into a second one of the slots at the lesser radial distance such that the second conductor extends out of the second one of the slots. A free end of the inserted second conductor is bent in each of the two orthogonal directions.
