Description
Technical field
The present invention relates to machine field, particularly a kind of bimorph transducer single rotor plane refrigeration compressor motor that can regulate motor speed according to refrigerating state for refrigerant compressor.
Background technology
Current most of refrigerating compressor for refrigerator motor uses common individual event alternating current machine, although this motor is fairly simple in 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 defect that this motor is fatal is that speed is uncontrollable, can only run under a kind of speed; And this rotor makes employing die casting cast aluminium, the performance of motor restricts the die casting quality in rotor to a great extent.Energy-conservation needs considered in use by refrigerant compressor, usually make motor start frequently, create larger noise; This startup frequently can have a significant impact the life-span of motor on the other hand, directly can have influence on the useful life of compressor, indirectly cause the waste of social resources.Part refrigerator is also had to use 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 winding of whole motor all in working order, in order to energy-conservation, motor is run under slower rotating speed, and it is very serious to cause that the motor feels hot, wastes a large amount of energy.The rotor of the motor of current use is all adopt silicon steel to fold riveting to form, and the domestic deficiency being limited to iron and steel output, makes holding at high price of silicon steel at present, makes the also corresponding raising of the manufacturing cost of motor.
Summary of the invention
The electric efficiency that the object of the invention is to exist for the existing refrigeration compressor motor described in background technology is not high, waste 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, high in cost of production problem, provide a kind of and can solve the energy-efficient of foregoing problems, rotating speed is controlled, and energising winding is controlled, and manufacture craft is simple, the bimorph transducer single rotor refrigeration compressor motor that cost is lower again.
The technical scheme realizing object of the present invention is as follows:
A kind of bimorph transducer single rotor plane refrigeration compressor motor, it comprises two groups of stators, a group rotor, rotating shaft and the fixed mount 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 the both sides of the circular end face of rotor respectively, often organize stator and comprise the fan-shaped stator module of polylith, described fixed mount comprises the outer ring be arranged at outside stator module and the parting bead be arranged 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, in the wire casing of coil winding in the middle part of stator core.
Often organize stator and comprise four stator modules, the central angle of stator module is 90 °.
Bimorph transducer single rotor plane refrigeration compressor motor of the present invention is the motor that DC power supply drives, motor adopts circuit board to control, and circuit board can combine with the control circuit board of the electric equipment such as refrigerator of this compressor electric motor of equipment, thus reduce the manufacturing cost of whole refrigerator.Owing to adopting circuit board to control motor, the speed of motor is adjustable controlled.Motor can be made to run with higher rotating speed with bimorph transducer simultaneously thus realize fast-refrigerating when the temperature of refrigerator is higher, and motor may be allowed to be incubated with the operation of lower speed with single stator when refrigerator temperature is lower, can again each humidity province with various rotating speed, the stator operational mode of different quantity switches freely, thus 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, is minimumly low to moderate 100r/min.But when low speed and high speed, COP value can reach higher level, all more than 1.95, therefore has very large advantage to energy-conservation.The present invention 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 adopt the mode that winding is concentrated, the low voltage starting for motor is very favourable; Stator core is once cast by soft magnetic material to form, and do not need to use silicon steel to be overrided to form.This kind of use unshakable in one's determination, reduces manufacture difficulty, more can adapt to making in enormous quantities than common electric machine.Rotor is that permanent magnet sintering forms, and this design, owing to being do not need die casting and exempt from other low manufacture difficulty, more adapting to manufacture in enormous quantities, significantly reduces rotor and cause volume to scrap because of die casting and filling impact.
