Refrigerant compressor

PROBLEM TO BE SOLVED : To provide a refrigerant compressor capable of restricting a leak current to a regulated value or below which uses an HFC-series refrigerant and a new refrigerant composed of an ether-based lubricant or an ester-based lubricant. SOLUTION : Even when the HFC-based refrigerant such as R410A, R407C, etc., and the ether-based or ester-based lubricant are used as the new refrigerant, the leak current responds to a motor volume. And then a lamination height of a core can be reduced for reducing the motor volume and the leak current consequently to restrict the leak current to the regulated value or below by using a rare earth magnet made of neodymium, boron, etc., having a very large BH product as a rotator magnet of a direct current brushless motor for the inverter-driven compressor.
