Abstract: An electric compressor includes an electric motor including a rotor and stator and a shaft rotating with the rotor to drive a compressor impeller. Bearings support the shaft. A housing encloses the impeller shaft, the bearings and the electric motor, and a sensor for sensing a condition within the housing. A control for the electric motor receives information from the sensor indicative of the potential of migrated refrigerant when the electric motor is not running. The control is operable to actuate a countermeasure to deliver heat into the housing to boil off the migrated refrigerant. A method is also disclosed.
