ABSTRACT:
In order to insulate in a simple manner the basically bare rotor shaft region between the one rotor stack end face (21) and the oppositely located commutator end face (51) at its circumference, a sleeve (4) which can be upset (collapsed) axially, is fabricated as a unitized part and is formed preferably integrally at the collar (31) of the insulating end disc (3) covering the rotor stack end face (21), is put on before the commutator (5) is pressed on, and is axially collapsed when the commutator (5) is pressed on.
