ABSTRACT:
A rotor having a thermal bridge embedded in the rotor for transferring heat released by the commutator of the rotor to the inner bushing of the drive shaft of the electric motor thereby cooling the rotor. The bridge may either be formed of a solid metal piece or a fluid containing conduits; both of which are electrically insulated from the commutator. Orifices are formed in the thermal bridge so that both halfs of the resin molded commutator can be joined together and form a stronger rotor.
