Detailed Description
The present invention will be further described with reference to the accompanying drawings.
As shown in the figure, the stator core for the energy-saving motor is composed of a plurality of silicon steel sheets 1 with different specifications, the silicon steel sheets 1 are I-shaped, and the upper end and the lower end of each silicon steel sheet comprise a pole shoe short side 2 and a pole shoe bevel edge 3, so that an I shape which is symmetrical up and down is formed. The silicon steel sheets 1 are arranged from large to small in sequence, the width of the largest silicon steel sheet 1 is 105mm, the width of the smallest silicon steel sheet 1 is 56mm, and the whole arranged silicon steel sheets 1 are isosceles trapezoids in a top view.
Further, the thickness of silicon steel sheet is 0.2 mm.
Through adopting above-mentioned technical scheme, the silicon steel sheet adopts 0.2 mm's thickness, under the unchangeable condition of other conditions, the conversion efficiency of increase motor that can the at utmost.
Furthermore, the length of the short side of the pole shoe is 7mm, and the inclined angle of the inclined side of the pole shoe is 60 degrees.
Through adopting above-mentioned technical scheme, increase the pole shoe angle on four angles of silicon steel sheet, under the normal circumstances of guaranteeing the winding, reduce the silicon steel sheet volume, reduce the magnetic flow loss.
Further, the bottom angle of the isosceles trapezoid formed by the silicon steel sheets is 60 degrees.
By adopting the technical scheme, the base angle is 60 degrees, and the number of the stator cores is limited by forming the stator by six same stator iron properties.
The specific use method comprises the following steps: six identical stator cores are selected according to the base angle of the isosceles trapezoid of 60 degrees. Six stator cores are sequentially and circumferentially arranged along the inclined edge of the isosceles trapezoid to form a stator, a winding is wound in the middle of the I-shaped silicon steel sheet 1, and the stator and the rotor are matched for use.
The utility model improves the magnetic flow area of the stator core and reduces the air gap area by changing the structural style of the silicon steel sheet, so that the motor has higher energy conversion efficiency; under the same energy requirement, the appearance volume of the motor is relatively reduced, the motor can be used in special occasions with small occupied area, and the practicability and the economic benefit are increased.
It should be known to those skilled in the art that the protection scheme of the present invention is not limited to the above-mentioned embodiments, and various permutations, combinations and transformations can be performed on the basis of the above-mentioned embodiments, without violating the spirit of the present invention, all the transformations performed by the present invention fall within the protection scope of the present invention.
