Abstract
PURPOSE: To enhance the efficiency as a motor and reduced power consumption by using a permanent magnet type rotor in a motor section which is a drive source for the enclosed type motor compressor.
CONSTITUTION: Since the drive source consists of a synchronous motor utilizing the permanent magnet type rotor 23, a magnetic field for generating torque is provided by a permanent magnet 31 and the efficiency of the motor 22 is enhanced. Accordingly, when the motor compressor is used in a refrigerator or an air conditioner, power consumption is reduced. In addition, by providing an upper balance weight 37 at the upper part of the permanent magnet 31 and resin-molding the weight 37 as one body with the magnet 31, the productivity of the permanent magnet type rotor 23 is enhanced. Furthermore, by providing the permanent magnet 31 on the inside of a rotor yoke 26, it is possible to use a ferrite magnet which is inexpensive although low in strength.
