A compressor (22) has a housing assembly (40) with a suction port (24), a discharge port (26), and a motor compartment (60). An electric motor (42) has a stator (62) within the motor compartment and a rotor (64) within the stator. The rotor is mounted for rotation about a rotor axis (500). One or more working elements (44) are coupled to the rotor to be driven by the rotor in at least a first condition so as to draw fluid in through the suction port and discharge the fluid from the discharge port. A gap (80) is between the rotor and stator. The gap is isolated (140, 142) from an outer portion (144) of the motor compartment. The outer portion is exposed to the stator. One or more passages (150) are positioned to draw fluid from the gap in the first condition. |
