ABSTRACT:
A rotor in an electric motor comprises a shaft having a commutator and armature thereon. To prevent relative movement between the armature lamination stack and the commutator, a structural coating such as epoxy resin coats the shaft between the commutator and stack. The commutator base has a coaxial recess in the adjacent end. The base is urged towards the stack while the coating is still fluid to gather up the coating so that it is of substantial thickness on the shaft, at least partially filling the recess and a radial slot in the recess wall.
