Abstract
A method and apparatus are provided for determining angular alignment between a lamination stack, a commutator, and coil windings of an armature for an electric motor. The apparatus has a body with an aperture for extending about the commutator, and a post for fitting into the lamination stack to locate an indicator slot and graphic symbols relative to the lamination stack for visually comparing alignment between the lamination stack, the commutator, and the coil windings.
