INTERNAL CLOSED LOOP COOLING

摘要

An electric motor having internal closed loop cooling includes a cooling chamber coupled to the stator cover of the electric motor. A fan is positioned to circulate air through the interior of the electric motor and the cooling chamber. A heat sink in the cooling chamber removes heat from the circulating air. The heat sink may be coupled to a fluid cooling jacket to transfer heat thereto or therefrom.
