ABSTRACT:
An armature end protector for protecting rotor windings from the end of a rotor stack, includes a hub and a body portion. The body portion has a plurality of radially extending spokes which cover arms of laminated members of the rotor, at least in the region of the rotor windings. The body portion is fitted to and supported by the hub. A circumferentially extending ridge is formed on the hub to provide a stop against which the body portion abuts to correctly locate the body portion on the hub. The ridge also increases the electrical separation distance between the rotor windings and the rotor stack.
