Abstract
The utility model provides a stator punching sheet for a motor of a washing machine. In the utility model, a hollow inner circular hole is formed in the middle of the stator punching sheet, and a plurality of punching sheet grooves are uniformly formed between the outer periphery of the stator punching sheet and the hollow inner circular hole in the radial direction of the stator punching sheet. The stator punching sheet is characterized in that the diameter Phi A of an externally tangent circle of the stator punching sheet is 147-152mm, and the diameter Phi B of the inner circle of the hollow inner circular hole is 68-72mm; the width C of each groove mouth is 2.0-2.2mm, and the height D1 of each groove mouth is 0.5-0.8mm; the shoulder height D2 of each groove is 0.5-0.7mm, and the top radius R of each groove is 3.8-4.0mm; the diameter Phi B1 of a circle tangent to the groove top is 100-102mm; and the x*y of the shape of the stator punching sheet is 118*118mm. The stator punching sheet has low cost, and the temperature rise of the motor is optimized; and the maximum power of the motor adopting the stator punching sheet can reach more than 300w.
Description
Technical field
The utility model is the stator punching of a kind of stator punching of motor, particularly a kind of motor for washer, belongs to the improvement technology of the stator punching of motor for washer.
Background technology
The motor of existing family expenses rotary drum washing machine is because stator punching overall dimension is little, groove top size is dark, the close height of yoke portion magnetic that causes stator punching, therefore, need remedy by the number of turn that increases winding, so not only cost height, and electric machine temperature rise also is difficult to be optimized, and the maximum power of motor also can only be accomplished below the 300W.
Increase in demand along with super capacity washer, in order to obtain more powerful motor, must design the bigger stator outer diameter and the punching of grooved, but keep the moment of inertia of rotor constant again simultaneously, therefore, the selection of the shape of stator punching and size becomes extremely important.
Summary of the invention
The purpose of this utility model is to consider the problems referred to above and provides a kind of rational in infrastructure, not only is suitable for heavy-duty motor, and the stator punching of the low motor for washer of cost.
The technical solution of the utility model is: a kind of stator punching of motor for washer, circular hole in the hollow has been made at the middle part of stator punching, be evenly distributed with the some punching grooves that are provided with along the radial direction of stator punching in the outer peripheral edges of stator punching and the hollow between the circular hole, the circumcircle diameter A that it is characterized in that described stator punching is 147-152mm, the interior circular diameter B of circular hole is 68～72mm in the hollow, slot opening C is 2.0-2.2mm, the high D1 of notch is 0.5-0.8mm, groove shoulder height D2 is 0.5-0.7mm, groove top radius R is 3.8-4.0mm, pushing up tangent diameter of a circle B1 with groove is 100-102mm, and punching profile X * Y is 118 * 118mm.
Described punching groove is provided with 24.
The utility model is because employing punching profile is 118 * 118mm and the structure of having optimized punching groove size, make the close step-down of yoke portion magnetic, do not need to remedy by the number of turn that increases winding, therefore, not only cost is low, and electric machine temperature rise optimizes the most, uses the utility model stator punching, and the maximum power of motor is accomplished more than the 300W.
