摘要：
A sealed compressor includes a housing for receiving a compressor pump unit and an electric motor. The electric motor drives a driveshaft. The driveshaft extends to drive an element within the compressor pump unit to compress a fluid. The motor includes a rotor spaced from a portion of the housing by a gap. The driveshaft drives a counterweight, which has a radially outermost portion extending radially outwardly beyond a radially innermost portion of the stator. The radially outermost portion of the counterweight has an angled face to drive fluid into the gap.
