Methods and apparatus for marking and identifying hooks of electric motor collectors |
(57) Methods and apparatus for marking and identifying a commutator hook of an electric
motor are provided. A preselected commutator hook is marked by deforming the hook
while the armature is in a winding machine, with a known angular position. The marked
hook is identified by apparatus which determines whether or not the hook has been
deformed while in the winding machine, and thereby recognizing the hook.
