Description
Technical field
The invention belongs to the compressor electric motor field, particularly relate to and a kind ofly can improve electric efficiency, improve the stator rotor structure of the cooler compressor of rotor revolution number and Max. torque with single-phase inducing motor.
Background technology
Compressor is the important composition parts that air conditioner, refrigerator etc. utilize the household electrical appliance of cooling cycle system work.The rolling piston of compressor changes mechanical energy into the pressure energy under the drive of motor, realize the compression to the compresser cylinder inner refrigerant.Motor converts electrical energy into the rotary machine energy by the rotation of corresponding component under the current field effect, for the running of compressor provides power.Therefore, motor is the vitals of compressor, and its behavior in service directly influences the function performance of compressor.
In general, motor is made up of stator and rotor two parts, and stator and rotor are made of the stacked iron core that forms of silicon steel core sheet respectively.Single stator lamination is circular, is cylindric by the stacked stator core that constitutes of lamination.Rotor is cylindric, and rotor directly is pressed on the bent axle and inserts in the cylinder cavity of stator core, has air-gap to be separated by between rotor and the stator.Embed the winding of enamelled wire coiled on the stator, stator winding outside source current by the time produce magnetic field.Rotor interacts with stator field when having electric current to pass through, and the generation electromagnetic torque also rotates in stator.
The household electrical appliance that power is slightly little as window air conditioner, wall-hanging air conditioner etc., adopt monophase machine mostly.Be not with the enamelled wire winding on the monophase machine rotor, the electric current in the rotor is not supplied with by external power, but is induced by stator field, and induced current and former magnetic field interaction make rotor rotation.
Stator comprises: by the winding of the enamelled wire coiled that embeds in stacked stator core that constitutes of silicon steel core sheet and the stator shaft orientation groove; Stator monolithic lamination is circular.
Rotor comprises:. rotor core, cage type winding portion.Cage type winding portion has several stubs, end ring portion and counterweight portion.Rotor core is formed with axis hole in inside, and the exterior periphery direction is shaped on several grooves that radially distributes.Rotor core is laminated by the insulation of circular iron core sheet, and every rotor lamination also has groove and axis hole.
There are following problem in the stator of prior art, rotor core:
The groove shape of cross section of the rotor lamination of prior art is that the big end of periphery is wide, and to the short and thick shape that the center of circle narrows down gradually, area is little.As shown in Figure 3, the technical parameter of stator, rotor lamination is as follows:
B：11.96 W：19.5 H：7.24 T：2.39
D1：112.04 D2：56
B/W＝0.6133 T/B＝0.1998
H/B＝0.6054 D2/D1＝0.4998
Wherein the implication of each letter representative is as follows:
B: the width T of rotor yoke: the spacing of groove
W: the rotor internal diameter is to the distance H of external diameter: the length of groove
D1: the outer diameter D 2 of stator: the internal diameter of stator
The lamination of rotor core is because the groove area is little, and groove inner wire rod resistance is big, and rotor easily generates heat, thereby causes electric efficiency low.And the stub volume is little, and the induced current of stub is less than normal, so rotor revolution number and peak torque are on the low side.
