Abstract

Single-phase two pole motors, comprise annular stator core punching and rotor iron core lamination, it is characterized by: in 24 opening wire casings of the inner ring distribution of stator core stamping sheet, four are had to be little wire casing, described little wire casing is between two main windings, and correspondence 180 ° of settings each other between two, rotor iron core lamination then take groove number be 18 wire casing structure mode of remaining silent.Owing to taking described structure, significantly increase stator core area, improve iron core utilization, under the close the same terms of magnetic, obviously increase rotating torque, improve motor working efficiency, reduce umber of turn and save wire, force winding conducting wire to concentrate on notch simultaneously, and then improve motor overload ability.And the wire casing structure of remaining silent of rotor iron core lamination, can effectively reduce electric motor starting electric current, increase detent torque, make it start fast under lower supply power voltage.And there is novel, rational in infrastructure, dependable performance, be applicable to the advantages such as popularization.

Description

Single-phase two pole motors

Technical field

The utility model relates to the improvement of stator to single-phase two pole motors and rotor core trench structure.

Background technology

Stator core and rotor core are the important component parts of motor, and the trench structure of iron core directly affects power output and the startability of motor.At present, usually the motor that the stator core being 175mm with external diameter is formed, the centre-height of finished product motor be 112mm single-phase its stator core of two pole motors in the grooved of wire casing be consistent, that is the shape and the size that form all wire casings in the punching of iron core and the facewidth are all the same, and the wire casing of the stator core of existing common motor is all larger, teeth portion is narrower, and yoke portion is thinner, and the utilance of iron core is also lower.

The patent No. 201220746498.2 disclosed " the single-phase 2 pole motor stator cores of 112 types ", it changes the groove number of stator core into 24 grooves by 30 grooves of common motor, decrease the number of turn of winding, save wire, on this basis, also increase the width of tooth and groove, yoke portion is increased, thus make the service behaviour of motor obtain improvement to a certain extent.But still it is not bery desirable.And its groove area of rotor iron core lamination of single-phase two pole motors is also larger, cause the cage bar of " mouse cage " comparatively thick, bring certain difficulty also to the startup of motor.

Summary of the invention

The purpose of this utility model is to solve Problems existing in background technology.

The technical solution of the utility model: described single-phase two pole motors, comprise stator core stamping sheet and the rotor iron core lamination of annular, it is characterized by: in 24 opening wire casings of the inner ring distribution of stator core stamping sheet, four are had to be little wire casing, described little wire casing is between two main windings, and correspondence 180 ° of settings each other between two, rotor iron core lamination then take groove number be 18 wire casing structure of remaining silent.

Its width of rebate of opening wire casing of described stator core stamping sheet is 2.6-3.0mm, the wide 24-28mm of yoke; The wire casing degree of depth is respectively 13-13.5mm, 10-10.3mm;

In described rotor iron core lamination, the area of each wire casing of remaining silent is 35-40mm ².

The beneficial effects of the utility model: owing to being provided with the stator core stamping sheet of little wire casing and less width of rebate and the wire casing degree of depth, not only significantly increase stator core area, improve iron core utilization, when magnetic close identical obviously increase rotating torque, improve motor operating efficiency, reduce winding total number of turns and save wire, force winding conducting wire more to concentrate on notch simultaneously, and then improve the overload capacity of motor.And take wire casing structure of remaining silent due to rotor iron core lamination, effectively can reduce the starting current of motor, add little flute profile (compared with the prior art) structure of the present utility model, the detent torque of motor can be increased further, make it start fast under lower supply power voltage.And there is novel, rational in infrastructure, dependable performance, be applicable to the advantages such as popularization.

Accompanying drawing explanation

Fig. 1 is stator core stamping sheet schematic diagram of the present utility model;

Fig. 2 is rotor iron core lamination schematic diagram of the present utility model.

Embodiment

Accompanying drawing 1 is the stator core stamping sheet 1 of single-phase two pole motors, the aperture lines slot type structure of its to be groove number be 24 groove, in 24 opening wire casings of inner ring distribution, has four to be little wire casing 3, described little wire casing 3 is between two main windings, and correspondence 180 ° of settings each other between two.On stator core stamping sheet 1 shown in figure, all opening wire casing width of rebate are 2.6mm, and yoke is wide is 25mm, 28mm respectively; The wire casing degree of depth is respectively 13.4mm, 10.3mm; As can be seen here, stator core stamping sheet groove area of reaching the standard grade obviously diminishes, the facewidth and the wide increase of yoke, especially more aobvious outstanding at little wire casing position.It effectively can improve efficiency and the overload capacity of motor.

Accompanying drawing 2 is rotor iron core laminations 2 of single-phase two pole motors, and it arranges at the outer ring of punching 2 frame mode that groove number is the wire casing 4 of remaining silent of 18.Wherein the area of each wire casing of remaining silent is 40mm ².Compared with prior art, relatively reduce the area of wire casing, be equivalent to winding conducting wire and attenuate, core area increases, and adds the setting of wire casing of remaining silent, the power factor of motor and startability are all improved significantly.
