It referring to figs. 1 to 4, is preferred embodiment provided by the utility model.

Double-side stator and motor provided in this embodiment are generated respectively by two end faces of double-side stator 11 for rotor The magnetic field of rotation rotates simultaneously for multiple rotors, thus the torque that output is bigger.

Double-side stator 11 provided in this embodiment, including shell and multiple iron cores 111, shell have annular cavity, ring Shape cavity runs through the front end face and rear end face of shell, forms front opening and open rearward end, and multiple iron cores surround and are arranged in In annular cavity, iron core 111 is respectively provided with the front end face of shell and rear end face towards identical upper surface and lower end surface, The upper surface and lower end surface of iron core 111 are wound with winding respectively, and in the front opening of the annular cavity of shell and rear end Colloid is perfused in opening respectively, is covered with annular cavity and forms covering glue layer.

It is arranged in annular cavity in this way, multiple iron cores 111 are surround, and covering glue layer is covered with annular cavity, makes more A iron core 111 can stablize fixation, keep annular shape not easily shifted, and in the upper surface and lower end of this multiple iron core 111 Face winds winding respectively, and after the winding of winding is powered, the front end face and rear end face of shell can be respectively formed with magnetic field, can be for The rotor of two sides rotates respectively.

Specifically, iron core 111 be in I-shaped shape, I-shaped shape iron core 111 include be formed with the upper piece 1111 of upper surface with And it is formed with the lower piece 1112 of lower end surface, upper piece 1111 and lower piece 1112 are connected by vertical sheet body 1113, in this way, When winding winding, winding is respectively wound around upper piece 1111 and lower piece 1112, convenient for winding, and is evenly distributed.

Also, the extending direction of the length of the vertical sheet body 1113 of multiple iron cores 111 is collected to the center of circle of annular cavity, this Sample, circular more stable of multiple iron cores 111, meanwhile, cored 111 through-hole is formed between two I-shaped shape iron cores 111, is convenient for The stable winding of winding.

And there is gap between adjacent iron core 111, it is embedded in gap by rubber cover group to stablize each iron core 111, And upper piece 1111 and the trapezoidal shape of lower piece 1112, the side wall of the upper piece 1111 of adjacent iron cores 111 are parallel to each other, The side wall of the lower piece 1112 of adjacent iron cores 111 is parallel to each other, and puts multiple iron cores 111 in order to regular, also, along far from ring On the direction in the center of circle of shape cavity, the height on 13 direction of shaft of upper piece 1111 and lower piece 1112 shortens, meanwhile, Outward from vertical sheet body 1113, the height on 13 direction of shaft of upper piece 1111 and lower piece 1112 shortens.

In this way, the winding being placed in 111 through-hole of iron core can be capped glue-line covering in order to avoid covering glue layer covers winding It fills up, and the winding for being placed in upper surface and lower end surface exposes outside covering glue layer, in order to which two end faces generate magnetic field respectively.

It is extended with multiple fixed blocks around shell, is fixedly connected by multiple fixed blocks with other structures, encapsulating covers Lid glue group will be fixed between this multiple fixed block and iron core 111.

The present embodiment also provides a kind of motor, including the fixed double-side stator 11 being installed in motor casing 15 and passes through production The rotor that raw magnetic field is rotated, rotor include the shaft 13 of outwardly output torque and the disk that is fixedly connected with shaft 13 Shape rotor, disc-like rotor are rotated by the magnetic field that double-side stator 11 generates.

In order to stablize fixed above-mentioned double-side stator 11, fixation is convexly equipped with multiple locating pieces, multiple locating pieces in motor casing 15 It overlaps, is fixedly connected with locating piece with fixed block by bolt, to keep the position of double-side stator 11 with multiple fixed blocks.

Pass through, the magnetic field that double-side stator 11 generates rotates disc-like rotor, and then shaft 13 is driven to rotate, outward Output torque.

Also, the middle part of shell has the round cavity 1121 passed through for shaft 13, and electricity is stretched out at the both ends of shaft 13 respectively The motor that casing 15, i.e. the present embodiment provide, both ends are extended with shaft 13, in order to which the motor is for different structure outputs Torque.

Specifically, shell is only the inner ring seal circle 112 for forming above-mentioned round cavity, by inner ring in the present embodiment Covering glue layer is filled between sealing ring 112 and above-mentioned multiple iron cores 111 and obtains double-side stator 11, and the periphery of shell is more The periphery of covering glue layer is perfused in a iron core 111, and the utility model draws shell only in order to express.

In addition, disc-like rotor includes the first disc-like rotor 121 and the second disc-like rotor 122, and and it is located at shell The two sides of body, in this way, the magnetic field that 11 two sides of double-side stator generate respectively is for the first disc-like rotor 121 and the second disc-like rotor 122 rotations, while the first disc-like rotor 121 and the second disc-like rotor 122 are rotated, in this way, with the first disc-like rotor 121 And second the torque that exports of the shaft 13 that is fixedly connected of disc-like rotor 122 it is bigger, in this way, easily facilitating 13 liang of above-mentioned shaft It holds while output torque is without generating any influence.

Also, the first disc-like rotor 121 and the upper surface of iron core 111 have the first running clearance, the second disc-like rotor 122 There is the second running clearance with the lower end surface of iron core 111, the first running clearance is identical at a distance from the second running clearance, in this way, Keep the revolving speed of the first disc-like rotor 121 and the second disc-like rotor 122 identical, prevents shaft 13 from twisting off.

Likewise, be wrapped in the winding of 111 upper surface of iron core with the winding for being wrapped in 111 lower end surface of iron core and be same root around Group, and canoe is identical, guarantees that the first disc-like rotor 121 is identical as the revolving speed of the second disc-like rotor 122, specific winding side Formula can be carried out according to actual needs.

In this way, connected between shaft 13 and motor casing 15 by bearing 14, specifically, bearing 14 be separately positioned on it is two-sided fixed The two sides of son 11 make the both ends stable rotation of Zi Zhou, stablize output.

The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle Within the scope of shield.
