In most semi hermetic compressors, the suction vapor is used to

Explanation:
Cooling the motor with suction vapor helps prevent overheating of the motor windings in a semi-hermetic unit. The suction gas from the evaporator flows through a path around the motor so it can absorb heat as it passes by the windings. As this heat-laden gas returns to the suction side, it continues through the cycle, keeping the motor temperature within safe limits and helping maintain efficiency and longevity. Lubrication is provided by oil in the compressor, not by the suction gas, and increasing refrigerant capacity isn’t achieved by this cooling arrangement.
