Abstract
A refrigeration compressor with an outer rotor structure comprises a first crankshaft, a first frame, an inner stator and an outer rotor, wherein the inner stator is fixedly connected with the first frame, and the outer rotor is connected with the first crankshaft and drives the same to work. The inner stator is arranged inside the refrigeration compressor, the outer rotor is arranged outside the refrigeration compressor, and via the adjustment in structural design, raw materials for the refrigeration compressor are reduced, size of the refrigeration compressor is reduced, and cost of the refrigeration compressor is saved. Since the diameter of the outer rotor of the refrigeration compressor is large, the refrigeration compressor is large in generated torque, small in running current, high in efficiency and easy to start under same conditions.
Description
Technical field
The present invention relates to a kind of compressor of refrigeration industry, particularly a kind of rotor is at the refrigeration compressor of the outer-rotor structure of stator outside.
Background technique
Compressor is as the core apparatus of chiller plant, and the quality of its performance plays vital effect to the normal operation of chiller plant.At present, the refrigeration compressor of the piston structure that uses both at home and abroad, the refrigeration compressor of eddy's structure, the refrigeration compressor of rotational structure, the refrigeration compressor of screw-rod structure, the refrigeration compressor of exocentric structure etc. all adopt the tactic pattern of rotor in stator, as shown in Figure 1, the compressor stator of this structure and the second frame are fixed, internal rotor is connected with the second bent axle, drives the second bent axle by internal rotor and carries out work.In the stator the inside, the external diameter of internal rotor must be less than the internal diameter of stator because of internal rotor for this kind structure, so the diameter of internal rotor is relatively little, the moment that produces under the equal conditions is little, causes running current large, difficulty in starting.
Summary of the invention
In order to overcome the deficiency of existing refrigeration compressor, the invention provides a kind of rotor design at the refrigeration compressor of stator outside structure, as shown in Figure 2, this compressor is because of the outside of external rotor at inner stator, so the external rotor diameter is large, the moment that under equal conditions produces is large, running current is little, efficient is high, easy startup.
For solving the problems of the technologies described above, the present invention realizes as follows: a kind of refrigeration compressor of outer-rotor structure comprises the first bent axle, the first frame, inner stator and external rotor.
Described inner stator is fixedly connected with the first frame.
Described external rotor is connected with the first bent axle, drives the first bent axle work by external rotor.
Good effect of the present invention is: a kind of refrigeration compressor of outer-rotor structure is provided, this compressor inner stator inside, external rotor outside, the adjustment of this project organization can reduce the raw material of product, the volume-diminished of product is saved product cost.And this compressor is because the external rotor diameter is large, and the moment that produces under the equal conditions is large, running current is little, efficient is high, easy startup.

Embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
A kind of refrigeration compressor of outer-rotor structure comprises the first bent axle (1), the first frame (2), inner stator (3) and external rotor (4).
As shown in Figure 2, described inner stator (3) is fixedly connected with the first frame (2).
Described external rotor (4) is connected with the first bent axle (1), drives the first bent axle (1) work by external rotor (4).
After this compressor energising operation, the coil above the inner stator (3) produces magnetic field, and under the effect in magnetic field, external rotor (4) rotates, and external rotor (4) drives the first bent axle (1) rotation, compressor starts work.
Claims (1)
1. the refrigeration compressor of an outer-rotor structure, comprise the first bent axle, the first frame, inner stator and external rotor, it is characterized in that: described external rotor is in the outside of inner stator, described inner stator is fixedly connected with the first frame, described external rotor is connected with the first bent axle, drives the first bent axle work by external rotor.
