Abstract
The invention relates to the technical field of the refrigerating industry, in particular to stator stamped steel of a refrigerating motor. The stator stamped steel comprises a stator stamped steel body, a stator inner hole is formed in the stator stamped steel body, a plurality of stator grooves are evenly distributed between the outer circle of the stator stamped steel body and the stator inner hole in the circumferential direction, and a stator magnetic pole and a stator pole shoe are arranged between every two stator grooves. Arc-shaped pole shoe faces are arranged at the bottoms of the stator pole shoes. The stator grooves are arranged in an inclined mode, and the included angle formed between the plane perpendicular to the inner walls of the stator grooves and the stamped steel surface of the stator stamped steel body is 13-18 degrees. The stator pole shoes and the stator magnetic poles are fixedly connected through screws. When the stator stamped steel of the refrigerating motor is used, the area of the stator grooves is greatly increased, and the problem that line inserting is difficult or the yoke portion of an iron core is narrow is solved; meanwhile, the magnetic density can be reduced, electromagnetic noise can be reduced, and the overall cost performance of the motor can be improved. The stator stamped steel of the refrigerating motor has the advantages of being simple in structure, reasonable in arrangement, low in manufacturing cost and the like.

Background technology
Along with the develop rapidly of national economy, the quickening of modernization of industry paces, refrigerating system is widely applied in every profession and trade.The Energy-saving Projects of refrigeration plant has become the strategy of state key transformation and research and development at present! And the index of low energy consumption has become people and has selected one of important choice criteria of refrigeration plant.
Motor, as the vitals of refrigeration plant, also must improve energy-saving efficiency.The motor stator punching of refrigeration plant is all provided with interior circular hole conventionally at middle part, between the cylindrical of stator punching and interior circular hole, be along the circumferential direction evenly distributed with multiple stator slots.Motor is in the time running well, and (being identical load, same rotational speed), all exists groove area little under the same conditions, and difficult rule or iron core yoke portion are narrow, and magnetic density is large, easily produces the defects such as electromagnetic noise, has affected the cost performance of air conditioner motor.
Therefore be necessary the motor stator punching of existing refrigeration plant to carry out technological innovation further.
Summary of the invention
The object of the invention is to defect and deficiency for prior art, a kind of refrigeration motor stator punching simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution used in the present invention is:
A kind of refrigeration motor stator punching of the present invention, comprise stator punching body, the middle part of stator punching body is provided with stator inner hole, between the cylindrical of described stator punching body and stator inner hole, be along the circumferential direction evenly distributed with multiple stator slots, between two stator slots, be provided with magnetic pole of the stator and stator pole shoes; Stator pole shoes bottom is provided with the pole-shoe face of arc shape; And the angle between the punching sheet surface of the plane that stator slot inwall is perpendicular and stator punching body is 13～18 degree; Described stator pole shoes and magnetic pole of the stator are fixedly connected by screw.
Further, the angle and between perpendicular plane and the punching sheet surface of stator punching body of stator slot inwall is 15 degree.
Further, described pole-shoe face is provided with pore; The degree of depth of pore deepens gradually from the end to end of pore.
Further, the diameter of described pore becomes large gradually from the end to end of pore.
Adopt after said structure, beneficial effect of the present invention is: a kind of refrigeration motor stator punching of the present invention, comprise stator punching body, the middle part of stator punching body is provided with stator inner hole, between the cylindrical of described stator punching body and stator inner hole, be along the circumferential direction evenly distributed with multiple stator slots, between two stator slots, be provided with magnetic pole of the stator and stator pole shoes; Stator pole shoes bottom is provided with the pole-shoe face of arc shape; Described stator slot is tilting setting, and angle between perpendicular plane and the punching sheet surface of stator punching body of stator slot inwall is 13～18 degree; Described stator pole shoes and magnetic pole of the stator are fixedly connected by screw.Using time of the present invention, by tilting stator slot is set, greatly increase the area of stator slot, by separating stator pole shoes and magnetic pole of the stator, solve the problems such as difficult rule or iron core yoke portion be narrow; Can reduce magnetic density, reduce electromagnetic noise, improve the overall price/performance ratio of motor simultaneously.The advantages such as the present invention has simple in structure, arranges rationally, and cost of manufacture is low.
