Method for twisting an armature

摘要

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.

1. A method of fabricating an armature for a motor, comprising:
providing a laminated assembly having a length, a central axis, and a plurality of open slots each extending the length and each adapted and configured to locate one conductor at a first greater radial distance and another conductor at a second lesser radial distance; inserting a first conductor within one of the slots at the greater radial distance until the first conductor extends out of the slot; using a computer numerically controlled machine to electronically actuatably bend the inserted first conductor in each of a first direction and a second direction, the first direction being orthogonal to the second direction, computer software being used to guide actuation of the bending according to a first nonlinear bending profile, the first nonlinear bending profile defining an amount of axial translation applied to a free end of the first conductor as the laminated assembly is rotated about its central axis; inserting a second conductor within the slot at the lesser radial distance until the second conductor extends out of the slot; and using the computer numerically controlled machine to electronically actuatably bend the inserted second conductor in each of the first and second orthogonal directions, the computer software being used to guide actuation of the bending according to a second nonlinear bending profile, wherein the second profile is different than the first profile, the second nonlinear bending profile defining an amount of axial translation applied to a free end of the second conductor as the laminated assembly is rotated about its central axis.
