A heating, ventilation, air conditioning and/or refrigeration system with a compressor motor cooling system

A chiller system, comprising:

• a refrigerant loop comprising a compressor configured to circulate a refrigerant therethrough;
• a motor configured to drive rotation of the compressor, wherein the motor is a permanent magnet assisted synchronous reluctance (PMASR) motor comprising a rotor and ferrite magnets embedded within a body of the rotor;
• and
• a motor cooling system configured to direct a portion of the refrigerant from the refrigerant loop, through a housing of the PMASR motor to place the portion of the refrigerant in thermal communication with components of the PMASR motor, and from the housing back to the refrigerant loop.
