Abstract

The invention discloses an external rotor rotary compressor comprising: a shell body, a stator support, a stator, a rotor and a compression device. A chamber is formed in the shell body; the stator support is fixed in the chamber; the stator is fixed on the stator support; a stator coil is winded on the stator; the rotor is rotatably disposed on exterior of the stator in a sleeving manner; a magnet is embedded in the inner side, which is towards the stator, of the rotor; an upper end surface of the magnet is lower than the upper end surface of the stator; the compression device is arranged in the shell body; and the upper end of a crank shaft of the compression device is connected to the rotor. According to the external rotor rotary compressor in the embodiment, the upper end surface of the magnet of the rotor is lower than the upper end surface of the stator so that an axial electromagnetic force generated to the rotor is upward when the external rotor rotary compressor works, so that the axial force applied to the crank shaft by the rotor is reduced and further mechanical loss of the external rotor rotary compressor is reduced. The external rotor rotary compressor is improved in power consumption and is improved in reliability and performance.

Description

Technical field [0001] The present invention relates to the field of compressors, in particular to an external rotor rotary compressor. Background technique [0002] The rotary compressor is usually driven by a motor composed of a rotor and a stator. At present, the motors in conventional technologies are mostly built-in motors. The built-in motor has a rotor located inside the stator, and the motor is large in size, and the compressor space is limited, which limits the amount of permanent magnets, which is not conducive to improving the energy efficiency of the motor. [0003] In recent years, the feasibility of applying external rotor motors to compressors has attracted widespread attention. Among them, the rotor of the external rotor motor is located outside the stator, and the compressor constituted is an external rotor rotary compressor. [0004] Since the structure of the outer rotor motor is completely different from the structure of the inner rotor motor in the prior art, th...
