    Abstract: A vapor cycle compressor includes a motor section and a compression section operatively engaged with the motor section. A refrigerant path is in the motor section and in the compression section. The refrigerant path includes: a compression refrigerant path, for a single phase compression refrigerant, in the compression section; an inner rotor shaft refrigerant path, for a single phase inner rotor shaft refrigerant, in the compression section and in the motor section; and a stator refrigerant path, for a two phase stator refrigerant, in the motor section.

    Abstract: A housing for a drive system. The housing defines a motor cavity, an electronics cold plate, an oil cavity, and a coolant cavity. The coolant cavity defines a first coolant flow path configured to provide cooling to the motor cavity and the oil cavity. The coolant cavity defines a second flow path configured to provide cooling to the motor cavity and the cold plate. The housing defines a coolant inlet and a coolant outlet fluidically coupled to the first coolant flow path and the second coolant flow path, such that the first coolant flow path and the second coolant flow path are parallel fluid paths. In some applications the coolant paths can be connected in series. In some examples, the housing is configured to cause a counter-flow heat exchange between an oil flowing in the oil cavity and a coolant flowing in the first coolant flow path.
