Abstract
The utility model discloses a stator punching for piston-type refrigerating compressor motor, comprising a stator punching body, the middle part of which is provided with a round hole. The external circumference of the round hole is provided with a plurality of sector stator slots. The stator punching is standard square-shaped, with length ranging from 104 to 108mm and width ranging from 97 to 101mm. The round hole inner diameter D Phi ranges from 55 to 65mm; with the improvement of the outline and the boundary dimension of the motor stator punching and the re-design of the round hole inner diameter and the rebate dimension, the stator punching for piston-type refrigerating compressor motor meets the requirement of improving the motor efficiency under the circumstance of reducing the consumption of the silicon steel and the lacquered wire.
Description
(1) technical field:
The utility model relates to a kind of stator punching that is used for the Piston Refrigerant Compreessor motor.
(2) background technology:
According to statistics, the owning amount of China's refrigerator surpasses 100,000,000, and its power consumption accounts for more than 30% of home-use electric weight; At home, the development of energy-efficient refrigerator and development are subjected to the very big attention of each large refrigerator factory just day by day.Compressor is the key point that can refrigerator energy-conservation as the core component of refrigerator.Compressor will reach the requirement of saves energy, and motor must be raised the efficiency.At present, what hermetically sealed refrigerating compressor unit used is monocyclic-start induction motor, and its stator punching adopts circular configuration, diameter of stator bore little (φ 57mm), and notch broad (1.75mm) makes slot leakage lead increase.Electric current is big, and the conductor number that whenever is in series is many.Therefore, during the design motor windings, just have to strengthen the line footpath, increase the number of turn, thereby make copper consumption many, copper loss is big.
(3) summary of the invention:
The purpose of this utility model just provides and a kind ofly can effectively reduce stator current, reduces the conductor number that whenever is in series, and copper loss is little, the stator punching that is used for the Piston Refrigerant Compreessor motor that electric efficiency is high.
The utility model comprises the stator punching body, and its middle part has circular hole, is processed with some flaabellum shape stator slots along the circular hole excircle, it is characterized in that: described stator punching is accurate square structure, its length L is 104-108mm, and width H is 97-101mm, and described circular hole inside diameter D is φ 55-65mm.
Described stator slot width of rebate S is 1.29-1.50mm.
The utility model improves motor stator punching profile and overall dimension, and cooperate circular hole internal diameter and notch size to redesign, increased the circular hole internal diameter, reduced the stator punching Aspect Ratio, and the narrower notch of employing, thereby accomplish reducing under silicon steel and the enamelled wire consumption situation, can satisfy the requirement that improves electric efficiency again.
The utility model volume is little, and material is economized, and iron loss is little, the electric efficiency height.
(4) description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a stator slot structural representation among Fig. 1.
(5) embodiment:
Referring to Fig. 1, Fig. 2, the utility model comprises stator punching body 1, and its middle part has circular hole 2, and the circular hole inside diameter D is φ 55-65mm, is processed with some flaabellum shape stator slots 3 along the circular hole periphery, and width of rebate S is 1.29-1.50mm.In the utility model, stator punching is accurate square structure, and its length L is 104-108mm, and width H is 97-101mm, by above improvement, can reach economical with materials and reduce cost, and improves the purpose of electric efficiency.
Claims (2)
