Further illustrate the technical solution of the utility model below with reference to the accompanying drawings and specific embodiments.

Embodiment one

Referring to FIG. 1, the utility model embodiment provides a kind of cored linear motor of small size, including stator 10 and The mover 20 that the stator 10 moves reciprocatingly under acting on, the stator 10 include forming the substrate 11 of skewed slot and being arranged in institute State the magnet steel 12 (as shown in Figure 2) on skewed slot；The mover 20 includes being outward extended with the iron core 21 of toothed region 23 and being wrapped in The winding 22 of the toothed region 23.

It should be noted that the design of skewed slot magnet steel 12 is to reduce slot effect.

In the present embodiment, the toothed region 23 be disposed with from left to right first extended segment 231, several Two extended segments 232 and first extended segment 231 are wound with the winding 22 on each described second extended segment 232.

Wherein, the linearly arrangement of the winding 22, and there are gaps between the winding 22 and winding 22, using every It is isolated from column, as shown in Figure 4.

It should be noted that such 22 arrangement mode of winding can increase motor interior loop distribution density, motor is effectively shortened Length, and because reducing insulated column, significantly reduce slot effect.

Preferably, the mover 20 further includes T-nut 24, and the T-nut 24 is mounted on the iron core 21 and institute State the opposite side of toothed region 23.

Accordingly, side opposite with the toothed region 23 on the iron core 21 is also equipped with pacifies for the T-nut 24 The mounting groove of dress.

Wherein, the rounded shape in corner of the T-nut 24, as shown in Figure 3.

It should be noted that the T-nut 24 uses fillet design, motor wrapped resin can be prevented because of T-type spiral shell Female 24 expanded by heating stress releases cause to crack.

Referring to FIG. 4, it is preferred, several are offered on the iron core 21 for the inbuilt through-hole 211 of temperature and resistance.

Specifically, increasing through-hole 211 is used for silicon steel sheet loss of weight and embedded temperature and resistance, when temperature and resistance is embedded in through-hole When in 211, be conducive to monitor the temperature of motor in time.

Preferably, the iron core 21 is one or more, and multiple iron cores 21 are spliced into an entirety.

It should be noted that the mover 20 of motor is designed using Spliced type structure, it, will when needing more high thrust specification It is spliced into an entirety before and after two movers 20, that is, constitutes bigger specifications and models, as shown in Figure 5.

In the present embodiment, illustratively, at most production is effectively reduced up to 2400N in sliceable six movers 20, thrust Period.

Preferably, the iron core 21 is overrided to form by silicon steel sheet.

After the silicon steel sheet is using primary leaching insulated paint, automatic winding, coil copper factor are carried out by fully automatic wire winding machine Improve 10%.

In order to improve motor radiating power, other surfaces of the iron core 21 in addition to upper and lower surface carry out encapsulating encapsulation, And the upper and lower surface of the iron core 21 is coated with heat conductive silica gel rouge, as shown in Figure 6.

Specifically, taking away motor lower surface heat using air flowing, upper surface heat is diffused by mover 20. Under 25 DEG C of use conditions of room temperature, motor effective push can increase by 10%, and motor temperature is stably controlled within 60 DEG C.

The above, above embodiments are only to illustrate the technical solution of the utility model, rather than its limitations；Although ginseng The utility model is described in detail according to previous embodiment, those skilled in the art should understand that: it is still It is possible to modify the technical solutions described in the foregoing embodiments, or part of technical characteristic is equally replaced It changes；And these are modified or replaceed, various embodiments of the utility model technical solution that it does not separate the essence of the corresponding technical solution Spirit and scope.
