Abstract

A refrigeration compressor provided with an outer rotor structure comprises a first crankshaft, an inner stator and the outer rotor, wherein the inner stator is fixedly connected with a first rack, and the outer rotor is connected with the first crankshaft and drives the first crankshaft to operate. According to the compressor, the inner stator is arranged inside and the outer rotor is arranged outside, raw materials and the size of the product can be reduced due to the structural regulation of the design, and the product cost can be saved; additionally, the outer rotor of the compressor has a large diameter, therefore the moment on equal conditions is larger, the operating current is smaller, the efficiency is higher, and the compressor is easier to start.

Description

A kind of refrigeration compressor of outer-rotor structure

Technical field

The utility model relates to a kind of compressor of refrigeration industry, and 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 crucial effects 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 second frame are fixed, and internal rotor is connected with second bent axle, drive second bent axle by internal rotor and carry 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 equal conditions produces down is little, causes running current big, starts difficult.

The model utility content

In order to overcome the deficiency of existing refrigeration compressor; The utility model provides the refrigeration compressor of a kind of rotor design in stator outside structure; As shown in Figure 2; In the outside of inner stator, so the external rotor diameter is big, the moment that under equal conditions produces is big, running current is little, efficient is high, easy startup because of external rotor for this compressor.

For solving the problems of the technologies described above, the utility model is realized as follows: a kind of refrigeration compressor of outer-rotor structure comprises first bent axle, first frame, inner stator and external rotor.

Said inner stator is fixedly connected with first frame.

Said external rotor is connected with first bent axle, drives the first bent axle work by external rotor.

The good effect of the utility model is: the refrigeration compressor that a kind 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 practiced thrift product cost.And this compressor is because the external rotor diameter is big, and the moment that equal conditions produces down is big, running current is little, efficient is high, easy startup.

1. first bent axles among the figure, 2. first frame, 3. inner stator, 4. external rotor, 5. second bent axle, 6. second frame, 7. stator, 8. internal rotor.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.

A kind of refrigeration compressor of outer-rotor structure comprises first bent axle (1), first frame (2), inner stator (3) and external rotor (4).

As shown in Figure 2, said inner stator (3) is fixedly connected with first frame (2).

Said external rotor (4) is connected with first bent axle (1), drives 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 first bent axle (1) rotation, compressor starts work.

Claims

1. the refrigeration compressor of an outer-rotor structure; Comprise first bent axle, first frame; Inner stator and external rotor is characterized in that: said external rotor is in the outside of inner stator, and said inner stator is fixedly connected with first frame; Said external rotor is connected with first bent axle, drives the first bent axle work by external rotor.
