MOTOR FOR COMPRESSOR

摘要

PURPOSE: A motor for compressor is provided to prevent the rising of temperature by using an impeller to cool a stator coil. CONSTITUTION: A rotator(111) is installed on an inner side of a core of a stator and rotated by an electrical operation interacting with the stator. A stator shaft(113) is installed on a central axis of the rotator(111) and supports the rotating of the rotator(111). An impeller(120) is installed on both ends of the rotator(111). The impeller is formed so that the rotator(111) rotates to absorb a refrigerant of a compressor and belch up it and cools a coil of the stator. An inner diameter of the impeller(120) is larger than an outer diameter of a part where the impeller is assembled. The impeller(120) is molded in a body with the rotator(111) by a die-casting.
