Description
Technical field
The utility model relates to a kind of electric moto used in compressor.
Background technology
Electric moto used in compressor generally adopts the mode of external rotor electric machine, and it comprises shell, internal stator, external rotor, circuit board module for controlling, and external rotor connects output shaft, and output shaft connects compressor again.The shortcoming that existing electric moto used in compressor also exists is: the layout between each parts and unreasonable structure, causes existing electric moto used in compressor volume comparatively huge.
Summary of the invention
In order to overcome the above-mentioned deficiency of existing electric moto used in compressor, the utility model provides a kind of topology layout rational electric moto used in compressor.
The technical scheme in the invention for solving the technical problem is: a kind of electric moto used in compressor, comprise casing, internal stator, external rotor, circuit board module, described external rotor connects output shaft, the central authorities of described casing are provided with central sleeve, described output sleeve is in described central sleeve, and described output shaft is bearing in described central sleeve by bearing, described output shaft stretches out from the front end of described casing;
The rear end face of described casing is provided with an inner recess, skeleton before being fixed with one in described inner recess, the rear of described inner recess has a back skeleton, and described internal stator is arranged on described front skeleton and back skeleton, and described internal stator is enclosed within outside described central sleeve;
Described circuit board module is arranged on the front end face of described front skeleton, also comprises a hook terminal, and one end of described hook terminal is fixed on described front skeleton, and the other end of described hook terminal is fixed on described circuit board module;
Described external rotor is tubular, and this external rotor is placed on outside described internal stator, and the front portion of external rotor is inserted in described inner recess, the rear end of described output shaft and the rear end face of described external rotor affixed.
Further, the rear portion of the inwall of described external rotor is provided with the installing ring of convex, and the rear end face of described external rotor is connected with described installing ring by screw.
The utility model is in use, identical with existing electric moto used in compressor, carrys out transmission compressor, do not repeat them here by output shaft.
The beneficial effects of the utility model are: topology layout is more reasonable, can do less by the volume of motor.
