DC DRIVE ROTARY TYPE COMPRESSOR

摘要

PURPOSE:To improve efficiency by providing the rotor of a motor independently from a compressor section and constituting the rotor of the DC motor with a permanent magnet and a dedicated core. CONSTITUTION:A stator section 11 and a rotor section facing it and having permanent magnet 13 arranged with a core section 12 on the back are formed in an enclosed container 10 to constitute a DC type motor section. A rotary cylinder section 16 rotated integrally with the rotor section and a piston 20 are provided to form a compressor section. Since the motor section employs the DC type motor and is constituted of the permanent magnet and core section, losses such as the iron loss are very small, and the efficiency of a compressor can be improved.
