Abstract
A stator punching sheet of a single/three-phase constant power motor relates to a motor, and specifically relates to the technical field of structures of single/three-phase constant power motors. The stator punching sheet comprises a punching sheet body, and 36 winding slots are uniformly distributed on the same circumference of the punching sheet and each has an upper top wider than a lower bottom, wherein the ratio of the height of each winding slot to the width of the upper top of the winding slot is 1.7-1.75:1. According to the utility model, on the premise that the width of the upper top of the winding slot is not changed, the height of the winding slots is increased so as to make the ratio of the height of the winding slot to the width of the upper top of the winding slot to be 1.7-1.75:1, thereby increasing the effective area of the winding slots; and for the three windings, an A phase winding is designed to have a single-phase full power output, and a B phase and a C phase are designed to have three-phase full power outputs, thereby realizing the single/three-phase constant power output.
Description
Technical field
The utility model relates to motor, particularly the technical field of structures of single three-phase equal power motor.
Background technology
Existing monophase machine, three phase electric machine mainly are comprised of main shaft, stator punching, rotor punching, winding and fan blade, uniform 36 centripetal winding slotted eyes on the same circumference of stator punching, the upper top width of each winding slotted eye is greater than the width of going to the bottom, usually the upper top width of winding slotted eye is 8.3mm, the height of winding slotted eye is 10.8mm, namely height is about 1.3 with the ratio of upper top width, the slot for winding hole area that forms is less, its single-phase power output of three phase electric machine is 1/3 of three-phase power output, does not satisfy the demand of high-end customer.
Summary of the invention
It is large that the utility model purpose is to design a kind of slot for winding hole area, the stator punching of single three-phase equal power motor that power output is large.
The utility model comprises the punching main body, uniform 36 winding slotted eyes on the same circumference of punching main body, the upper top width of each winding slotted eye is characterized in that greater than the width of going to the bottom the height of each described winding slotted eye and slotted eye upper top Width are 1.7～1.75 ︰ 1.
The utility model is under the front topic of the upper top width that does not change the winding slotted eye, the height of each winding slotted eye is strengthened, making height and the slotted eye upper top Width of each described winding slotted eye is 1.7～1.75 ︰ 1, so can increase the effective area of winding slotted eye, can realize on this basis three phase windings wherein the A phase winding design by single-phase output full power, all the other B, C press the design of three-phase output full power mutually, thereby realize single three-phase equal power output.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is I section enlarged drawing among Fig. 1.
Embodiment
As shown in Figure 1, the utility model uniform 36 winding slotted eyes 2 on the same circumference of punching main body 1.
As shown in Figure 2, the upper top width D 1 of each winding slotted eye 2 is greater than the width D 2 of going to the bottom, and the height H of winding slotted eye 2 and slotted eye upper top width D 1 are than being 1.7～1.75 ︰ 1.
Concrete size can be: D1 is 8.3mm, and D2 is 3mm, and H is 14.5mm.
