Description

Outward rotation type motor stator structure-improved

Technical field

The utility model is meant a kind of outward rotation type motor stator structure-improved especially relevant for a kind of stator structure of motor.

Background technology

Its employed resistance enameled wire loop winding method complexity of conventional motor is just put into coil because of the stator silicon steel plate core needs enough areas, and is caused stator silicon steel plate core area to strengthen, and is beneficial to processing and manufacturing; And design is not good because of reeling, and makes it need to increase more program step in procedure for producing.

Other has traditional stator is that circle is wound with six groups of actuating coils and six groups of operating coils are finished on the silicon steel seat, on processing procedure, owing to coil is more, not only cause the silicon steel pedestal long-pending excessive, on cost, because of the more cost of coil increases relatively, fabrication steps is more again, and the deadline is relatively slow; Moreover, the pole height of this case all be lower than coil turn around after height, coil turn is easily formed around the back appears kenel, the effect that there is no the insulation blocking coil exists, and easily influences running efficiency because of external factor.

Summary of the invention

The utility model purpose is; a kind of outward rotation type motor stator structure-improved is provided; to overcome the defective of above-mentioned traditional structure; actuating coil and operating coils evenly are laid in the silicon steel seat wall; be subjected to the insulation blocking of insulated column wall; reach safety and evenly reach saving resistance enameled wire loop, reduce cost and purpose of power saving.

A kind of outward rotation type motor stator of the utility model structure-improved is characterized in that, comprises that one encloses on the silicon steel seat around four groups of actuating coils and four groups of main bodys that operating coils is formed; This silicon steel seat has several insulated columns and notch, each insulated column front end is formed with wall in addition, and wherein, the described actuating coil of respectively organizing is the corresponding both sides in silicon steel seat axle center, two notches of getting isometric distance respectively constitute around one group coil, and these four groups of actuating coils intersect kenel in twos mutually; Silicon steel seat axle center is enclosed around operating coils on two notches of isometric distance up and down in the same manner, and constitutes the intersection kenel in twos, and four groups of operating coils are overlying on the actuating coil outer rim.

Wherein, four groups of actuating coils are gone into the 5th notch by first notch of silicon steel seat axle center datum mark side respectively and are gone out, and second notch is gone into the 6th notch and gone out, and the 11 notch is gone into the 7th notch and gone out, and the 12 notch is gone into the 8th notch and gone out.

Wherein, four groups of operating coils are gone into the 8th notch by the 4th notch respectively and are gone out, and the 5th notch is gone into the 9th notch and gone out, and second notch is gone into the tenth notch and gone out, and the 3rd notch is gone into the 11 notch and gone out.

Wherein, four groups of actuating coils be the up time needle cycle around.

Wherein, four groups of operating coils be counterclockwise circle around.

Wherein, rotor is 17 grooves or 22 groove structures.

The utility model beneficial effect: by said structure, actuating coil and operating coils evenly are laid in the silicon steel seat wall, are subjected to the insulation blocking of insulated column wall, have safety evenly and save the resistance enameled wire loop, reduce cost and the effect of power saving.

Embodiment

Consult shown in Figure 1, the utility model is to form around four groups of actuating coils 2 and four groups of operating coils 3 in silicon steel seat 1 circle, wherein silicon steel seat 1 central authorities have axle center hole 10, be formed with datum mark 11 in axle center hole 10 upper ends, outer edge is provided with the insulated column 12 of even number, and insulated column 12 front ends are extended with the wall 13 of tool height, and 12 of each insulated columns are formed with notch 14, these notch 14 quantity and insulated column 12 identical (as Fig. 2).

Please consult shown in Figure 3 again, the circle that is the utility model actuating coil 2 streams journey and mode, at first with resistance enameled wire loop head end line by the notch A of nearest datum mark 11 around going into, notch E to specific range lays out, the coiling that is first group of actuating coil 2 is finished, immediately again by the clockwise adjacent side channel mouth B of notch A around going into, lay out with first group of identical adjacent side channel mouth F of actuating coil two notches distance, finish second group of actuating coil, these two groups of actuating coils be adopt the up time needle cycle around direction finish the resistance enameled wire loop around, then be cross spider circle kenel (as Fig. 4) after coil encircling is finished.

With being about to silicon steel seat 1 Rotate 180 angle, make the resistance enameled wire loop enter the opposite side of datum mark 11, then by the notch G of the notch K of the parallel correspondence of notch A and the parallel correspondence of notch E be coil around going into to lay out two notches, other carries out counterclockwise wound coil; Move to two notch L, the H of side adjacent side afterwards, carry out identical counterclockwise wound coil, finish two groups of actuating coils and be cross spider circle kenel, cause four groups of actuating coils and produce two cross coil kenels (as Fig. 5, Fig. 6).
