Abstract:
1. An integrated motor system comprised of a motor including a stator and a rotor within said stator; housing means attached in fixed position to said motor and defining a first chamber therewithin, lying adjacent to said motor, and a second chamber therewithin lying adjacent to said first chamber and remote from said motor, said motor, said first chamber and said second chamber being arranged seriatim in said motor system; thermal insulation means disposed between said first and second chambers; at least one heat-generating electrical component mounted on a mounting board contained in said first chamber of said housing means and operatively attached to said motor, said at least one heat-generating electrical component being disposed in effective heat conductive contact with said stator of said motor such that said stator functions as a heat sink for dissipation of thermal energy generated by said at least one heat-generating electrical component; and at least one heat-sensitive electrical component contained in said second chamber of said housing means; said thermal insulation means, so interposed, also being interposed between said at least one heat-sensitive electrical component and both said at least one heat-generating electrical component and also said motor to effectively thermally isolate said at least one heat-sensitive electrical component from said at least one heat-generating electrical component and said motor.
