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.
Description
technical field [0001] The invention relates to the technical field of the refrigeration industry, in particular to a stamping plate of a refrigeration motor stator. Background technique [0002] With the rapid development of the national economy and the acceleration of industrial modernization, refrigeration systems have been widely used in various industries. At present, the energy-saving project of refrigeration equipment has become a national key transformation and research and development strategy! Moreover, the index of low energy consumption has become one of the important selection criteria for people to choose refrigeration equipment. [0003] As an important part of refrigeration equipment, electric motors must also improve energy-saving efficiency. The motor stator punching sheet of the refrigeration equipment is usually provided with an inner circular hole in the middle, and a plurality of stator slots are evenly distributed along the circumferential direction ...
