Abstract

DC60 The objectives of this invention are: The construction of a low-cost, high-efficiency one-phase motor is based on a motor manufacturing method that uses just the right amount of material and at the same time maintain the magnetic path of the ion core. Of the stator as before The iron core of the stator 1 is obtained by piling a number of electromagnetic steel sheets. Together in the form of a laminate and it will have N grooves where N / 2 is an odd number and part of it. The other is a groove width 4, and the other part is a smaller groove 3 with a shallower depth in the circular direction and the main bundle of coils 6 is placed in a one-phase overlapping winding bundle. 2-pole inserted into wide groove 4 or small groove 3 and reinforced coil bundle 7 in one-phase, 2-pole overlapping coil bundle, inserted into wide groove 4 or small groove 3 and placed. At the point where the electrical angle from the primary coil bundle 6 greater than 90 degrees is included, and during the N groove, the groove occupies the area of the coil bundle. Less than other parts By placing the auxiliary coil bundle 7 at an angle from the main bundle coil, 6 more than 90 degrees will form a small groove 3, and the rest will be a wide groove. 4 purposes of this invention are: The construction of a low-cost, high-efficiency one-phase motor is based on a motor manufacturing method that uses just the right amount of material and at the same time maintain the magnetic path of the ion core. Of the stator as before The iron core of the stator 1 is obtained by piling a number of electromagnetic steel sheets. Together in the form of a laminate and it will have N grooves where N / 2 is an odd number and part of it. The other part will be a smaller trench 3 with a shallower depth in the circular direction and the primary coil bundle 6 is in a one-phase overlapping winding bundle. 2-pole inserted into groove 4 or small groove 3 and an auxiliary coil bundle 7 in a bundle of coils overlapped with a one-phase, 2-pole inserted into a groove 4 or small groove 3, and It is positioned at an angle from the primary coil bundle 6 greater than 90 degrees, and between the N grooves, the grooves occupy the area of the coil bundle. Less than other parts By placing the auxiliary coil bundle 7 at the point where the electrical angle from the main bundle winding 6 more than 90 degrees will be a small groove 3, and the rest will be a groove width 4.

Claims (7)

1. One phase motor Where The iron core of the stator obtained by taking a number of electromagnetic steel sheets. Let's stack them together like a laminate. Where on this axis there is a groove N, where N / 2 is an odd number and part of It will be a wide groove and the other will be a shallow groove in a circular direction, the primary winding of the one-phase overlapping winding bundle. 2- step that is inserted into Wide or small groove and auxiliary coil bundle of one-phase overlapping coil tie set. 2- the polarity that is inserted into Wide groove or small groove And placed at a point where the electrical angle from the primary coil bundle is greater than 90 degrees, where the space utilization or occupied area of the coil bundle is determined as the rate of The cross-sectional area of the coil bundle is used in the area of the groove and during the N groove, where the utilization rate Space or occupy less space of the coil bundle than other grooves By placing it an auxiliary coil at the point where At an electrical angle from the main bundle winding more than 90 degrees will be a small groove. And the remaining grooves will be wide grooves 2. One-phase motor as described in claim 1, where a number of notches will be formed in such a form as roughly linear sections where it will consist of a notch. Wide resting on the edge around the circle Outside of the small groove at the perimeter of the outer circle of the iron-on-stator axis and where the linear portion of the wide groove that rests on the periphery around the circle. The outside of the small groove is placed on the center side of the stator ion core in order to make the area Of the notch, which is a notch area that is wider than the other notches 3. One-phase motor, as specified in claim 2, where the wide notch rests at the edge. Around the outer circle of the small groove is positioned at a mechanical angle of 180 degrees. This creates a hexagon with a symmetrical axis composed of straight lines made up of notches. 4. One-phase motor as specified in claim 1, where the angle arising from the magnetic pole of the bundle The primary winding is caused by the passage of current through the primary winding. And the magnetic pole of the bundle The auxiliary coil generated by the current passing through the auxiliary coil bundle will be at least (90-360 / 2N) degrees. But will not be greater than (90 + 360 / 2N) degree 5.One-phase motor, as defined in any of Clause 1 to Clause 4.
