Common compressor comprises a motor unit, and motor unit has a stator and a rotor, and rotor is rotatably installed near the stator, also comprises a bent axle, a connecting rod and a piston.Be wound with coil on the stator, produce the magnetic line of force between stator and the rotor, under the situation of energising, magnetic flux changes and makes rotor rotation.
The thickness of stator is big more, and the power of output is big more, and still along with the increase of stator thickness, corresponding power consumption also increases, thereby the loss that causes also increases, and can reduce the power of output on the contrary.
Summary of the invention
The invention solves in the prior art needs constantly the thickness of increase stator to increase the shortcoming of power consumption on the contrary for reaching appropriate output power, provide a kind of power output constant but can reduce stator thickness, improve power output, performance, and the single-phase motor for refrigeration compressor that reduces cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of single-phase motor for refrigeration compressor, comprise stator and be arranged on the rotor that matches with stator in the stator, be wound with coil on the stator, wherein, stator is to be laminated by the multi-disc stator piece, the centre of stator piece is provided with some roads groove, is 1.2mm-1.5mm towards the width of the notch of centre; Rotor is laminated by the multi-disc rotor sheet, and the edge of rotor sheet is provided with some roads sulculus, and sulculus is a dome over against an end of stator, and the angle of dome is 90 °; The quantity of the groove of stator piece is 6: 7 with the ratio of the quantity of the sulculus of rotor sheet.The groove of stator is used for fixing coil, and the width of the opening of the groove on the stator affects the magnetic flux variable, and the opening of groove is unsuitable excessive.
As preferably, the width of the notch of stator piece is 1.3mm-1.4mm.The width of stator slot is 1.2mm-1.5mm, particularly between 1.3mm-1.4mm, under the prerequisite of same power, can reduce the quantity of the stator piece of stack, make power consumption reach less requirement, and can guarantee enough power outputs, also can reduce the thickness of stator, thereby save material.
The quantity of stator film trap is 24 roads, and the quantity of rotor sheet sulculus is 28 roads.
The groove of stator piece is divided into the short groove of groove and 4 roads in 12 road deep trouths, 8 roads; The groove of stator piece is arranged according to axial symmetry.
The groove of stator piece takes the shape of the letter U, and at the bottom of the bottom of groove was arc, the width at the bottom of the arc was greater than the width of notch, and the both sides of groove are one section straight flange by the center, forms semi-enclosed notch at the aperture position of groove.
The radius of dome is R0.5mm, and the distance between the summit of dome and the edge of rotor is 0.3mm.
The outside of stator piece is stepped, and at crossover position chamfering rounding off.
Coil is arranged in the groove of stator, and the stacked back of rotor sheet is connected to form integral body by the aluminium core, and is arranged on the centre position of stator.
The invention has the beneficial effects as follows: adopt the groove of the width of 1.2mm-1.5mm, can improve the magnetic flux variable, under the prerequisite that guarantees same power output, can reduce power consumption, reduce the quantity of the stator piece of stack, thereby saved material, reduce cost, to improve Energy Efficiency Ratio.
