According to the utility model, the rotation speed of the double-stator single-rotor planar refrigeration compressor motor can be adjusted according to the temperature condition of a refrigerator, and the double-stator single-rotor planar refrigeration compressor motor is high in efficiency, energy-saving, simple in manufacturing process and low in manufacturing cost.
Description
Technical field
The utility model relates to machine field, particularly a kind of for refrigerant compressor can be according to the two stator single rotors planes refrigeration compressor motor of refrigerating state regulating electric machine rotating speed.
Background technology
What present most of refrigerating compressor for refrigerator motor used is common individual event alternating current machine, although this motor is fairly simple on making, electric efficiency is not high, and the COP value of common load motor is not more than 1.90, and noise is very large.The defective that this motor is fatal is that speed is uncontrollable, can only move under a kind of speed; And this rotor making employing die casting cast aluminium, the performance of motor restricts the die casting quality in rotor to a great extent.Refrigerant compressor is considered energy-conservation needs in use, usually makes motor start frequently, has produced larger noise; This life-span that starts frequently motor can have a significant impact on the other hand, can directly have influence on the useful life of compressor, indirectly causes the waste of social resources.What also have the use of part refrigerator is dc brushless motor, this motor has the controlled advantage of speed than common alternating current machine, but under keeping warm mode, due to be all windings of whole motor all in working order, for energy-conservation, make motor move under slower rotating speed, cause that the motor feels hot very serious, wasted a large amount of energy.The rotor of the motor that uses at present is all to adopt the folded riveting of silicon steel to form, and the domestic deficiency that is limited to iron and steel output, make holding at high price of silicon steel at present, makes the also corresponding raising of manufacturing cost of motor.
Summary of the invention
The purpose of this utility model is that the electric efficiency that exists for the existing refrigeration compressor motor described in background technology is not high, wastes energy; The motor feels hot that amount is large for dc brushless motor; Adopt silicon steel sheet to do stator core and rotor, complex process, the high in cost of production problem provides a kind of energy-efficient rotating speed that can solve foregoing problems controlled, and the energising winding is controlled, and manufacture craft is simple, and cost is lower two stator single rotor refrigeration compressor motors again.
The technical scheme that realizes the purpose of this utility model is as follows:
A kind of pair of stator single rotor plane refrigeration compressor motor, it comprises two groups of stators, a group rotor, rotating shaft and the fixed mount that is used for fixed stator, rotor is fixedly connected with rotating shaft, rotor is one-time formed columniform p-m rotor, two groups of stators are arranged at respectively the both sides of the circular end surface of rotor, every group of stator comprises the stator module that polylith is fan-shaped, described fixed mount comprises the outer ring that is arranged at the stator module outside and is arranged at parting bead between stator module, and fixed mount is fixedly connected with the shell of motor.
The stator core of described stator module is the stator core of the one-time formed hollow structure of soft magnetic material, and coil winding is in the wire casing at stator core middle part.
Every group of stator comprises four stator modules, and the central angle of stator module is 90 °.
Of the present utility model pair of stator single rotor plane refrigeration compressor motor is the motor that DC power supply drives, motor adopts circuit board to control, and circuit board can combine such as the control circuit board of refrigerator with the electric equipment of this compressor electric motor of equipment, thereby reduced the manufacturing cost of whole refrigerator.Owing to adopting circuit board to control motor, it is controlled that the speed of motor is adjustable.Thereby can make motor realize fast-refrigerating with higher rotating speed operation simultaneously with two stators when the temperature of refrigerator is higher, and may allow motor be incubated with lower speed operation with single stator when refrigerator temperature is low, each humidity province is with various rotating speeds again, the stator operational mode of different quantity is switched freely, thereby does not need motor to start frequently.The rotating speed adjustable extent of this compressor electric motor is wide, reaches as high as 8000r/min, minimumly is low to moderate 100r/min.But the COP value can reach higher level when low speed and high speed, all more than 1.95, therefore has a very large advantage to energy-conservation.The utility model is in order to adapt to the cooperation needs of other parts of compressor, and the endoporus of this rotor is the same with other common electric machines.Each stator core is wound around copper cash, and the mode that adopts winding to concentrate is very favourable for the low voltage starting of motor; Stator core is once to be cast by soft magnetic material to form, and need not use silicon steel to be overrided to form.The use of this kind iron core has reduced manufacture difficulty, more can adapt to making in enormous quantities than common electric machine.Rotor is that the permanent magnet sintering forms, this design adapts in enormous quantities the manufacturing more owing to being not need die casting and exempt from other low manufacture difficulty, has greatly reduced rotor and has caused volume to scrap because of the impact of die casting and can.
