Abstract
The utility model discloses a kind of stator structure of permanent magnet iron coreless brushless electric machine, it comprises casing and is arranged on the iron-core-free winding dish in casing, the center of winding dish is provided with installing hole, the circumferential side wall of winding dish is laid with some projections, and from one of them protruding extraction winding dish outlet, described casing is tubular structure, the madial wall of casing one end is laid with the axial notch suitable with described projection along its circumference, the madial wall of the casing other end is provided with the block body for blocking groove port.When the utility model is on permanent magnet iron coreless brushless electric machine, after motor receives stop command, winding dish at motor intrinsic displacement, thus can not reduce the vibration of motor, extends the useful life of motor.Winding dish directly contacts with casing, and the heat that energising winding produces can be directly conducted on casing, is conducive to the heat radiation of motor.
Description
Technical field
The utility model belongs to the stator technology field of permanent magnet iron coreless brushless electric machine, particularly relates to a kind of stator structure of permanent magnet iron coreless brushless electric machine.
Background technology
In the real work of permanent magnetic brushless, need to send stop command to motor, now winding dish can be subject to a reaction force instantaneously in body.If the rotating speed of motor is very high, it is shorter that urgency stops the required time, and reaction force is also larger instantaneously for this.If winding dish produces displacement under the reaction force of this moment, cause motor oscillating, winding dish will be damaged, reduce the useful life of motor.The motor of current iron-core-free, its stator winding contacts with air, and the pyroconductivity of air is very low, is unfavorable for the heat radiation of motor.
Summary of the invention
In order to solve the problems of the prior art, the purpose of this utility model is to provide a kind of stator structure of permanent magnet iron coreless brushless electric machine.
In order to realize technique scheme, the utility model adopts technical scheme as described below:
A kind of stator structure of permanent magnet iron coreless brushless electric machine, it comprises casing and is arranged on the iron-core-free winding dish in casing, the center of winding dish is provided with installing hole, the circumferential side wall of winding dish is laid with some projections, and from one of them protruding extraction winding dish outlet, described casing is tubular structure, the madial wall of casing one end is laid with the axial notch suitable with described projection along its circumference, the madial wall of the casing other end is provided with the block body for blocking groove port.
Owing to adopting technique scheme, the utility model has following superiority:
When the utility model is on permanent magnet iron coreless brushless electric machine, after motor receives stop command, winding dish at motor intrinsic displacement, thus can not reduce the vibration of motor, extends the useful life of motor.Winding dish directly contacts with casing, and the heat that energising winding produces can be directly conducted on casing, is conducive to the heat radiation of motor.

In figure: 1-winding dish; 2-is protruding; The outlet of 3-winding dish; 4-casing; 5-screwed hole; 6-groove; 7-block body; 8-end cap.
Embodiment
As shown in Figure 1, a kind of stator structure of permanent magnet iron coreless brushless electric machine, it iron-core-free winding dish 1 comprising casing 4 and be arranged in casing 4, the center of winding dish 1 is provided with installing hole, the circumferential side wall of winding dish 1 is laid with some protruding 2, and from one of them protruding extraction winding dish outlet 3, described casing 4 is tubular structure, the madial wall of casing 4 one end is laid with and described protruding 2 suitable axial notches 6 along its circumference, the madial wall of casing 4 other end is provided with the block body 7 for blocking groove port.
As shown in Figure 2, for better implementing the utility model, an end of casing 4 is also provided with circular end cap 8, an end face of end cap 8 is circumferentially laid with the guide vane end stop corresponding with described groove 6.
During installation, winding dish is fitted in casing, one end face of winding dish is close on the block body end face on internal side of shell wall, end cap is fitted on an end of casing, guide vane end stop on end cap is positioned at described groove, and guide vane end stop is close on the other end of winding dish, by the left and right sides of restriction winding dish, make winding dish without moving axially.
Block body 7 on described casing other end madial wall also can adopt above-mentioned end cap 8 to substitute, the groove 6 on casing is only needed to be set to groove, then all install an end cap at casing two ends, the guide vane end stop so just making the both sides of the winding dish in casing cover respectively by two side ends carries out spacing.Certainly, winding dish both sides also can separately designed component in order to limit moving axially of winding dish.
For better implementing the utility model, uniform on the lateral wall of casing 4 several screwed holes 5 for being fixedly connected with end cap are set.
In addition, winding dish outlet 3 can be drawn from any one or more projection, and is drawn by end cap 8, and this structure can prevent outlet from losing, simultaneously convenient arrangement, aesthetic appeal; And the outlet of winding dish not only can contain power line, also can be integrated as Hall element, temperature sensor etc. in winding dish, the wiring of these elements also can be drawn from high spot with power line together.
