Description
Technical field
The utility model relates to the brshless DC motor technical field, refers to especially a kind of brushless DC servo motor rotor.
Background technology
Brushless DC servomotor is a kind of direct current machine, and is lightweight because its volume is little, and it is large to exert oneself, and response is fast, and speed is high, and inertia is little, rotates smoothly, and the advantage such as moment is stable and obtain using more and more widely replaces traditional direct current machine gradually.
In addition, operation principle by brshless DC motor determines to need on its rotor to be bonded with the magnetic sheet that permanent magnet is made, existing technology generally is with adhesive that magnetic sheet and rotor block is bonding, yet this magnetic sheet can be subject to the effect of Ampere force on the one hand when machine operation, on the other hand also can be owing to the high-speed rotary of rotor transfers to produce centrifugal force, therefore it produces easily in the course of the work displacement even breaks away from rotor block under prior art, so that motor can't work even cause damage.
Therefore, for solving weak point of the prior art, provide a kind of can be effectively fixedly the brushless DC servo motor rotor of magnetic sheet seem particularly important.
Summary of the invention
Brushless DC servo motor rotor comprises rotating shaft, rotor block and even number sheet magnetic sheet, and described rotor block is fixedly sleeved in described rotating shaft, and described rotor block is provided with draw-in groove, and described magnetic sheet is provided with the card article with the draw-in groove phase clamping of rotor block.
Wherein, described rotating shaft two ends all are connected with end cap, described end cap be socketed on described rotating shaft and with the mutual clamping of described magnetic sheet.
Wherein, described end cap inner face is provided with the locating piece that equates with magnetic sheet quantity, and described locating piece is arranged in the gap between the adjacent magnetic sheet.
Wherein, mutual butt between described locating piece and the adjacent magnetic sheet.
Wherein, described end cap is stainless end cap.
Wherein, fixing by being spirally connected between described end cap and the rotating shaft.
Wherein, described magnetic sheet is with bonding by adhesive with rotor block.
The beneficial effects of the utility model: the utility model provides a kind of brushless DC servo motor rotor, comprise rotating shaft, rotor block and even number sheet magnetic sheet, described rotor block is fixedly sleeved in described rotating shaft, described rotor block is provided with draw-in groove, described magnetic sheet is provided with the card article corresponding with the draw-in groove of rotor block, described magnetic sheet and rotor block clamping.Compared with prior art, be connected fasteningly between magnetic sheet and the rotor, tighten between lower magnetic sheet and the rotor block running up, magnetic sheet is difficult for producing displacement or breaks away from rotor block.So that work under the condition that rotor can be adapted at running up.Only need magnetic sheet is breakked away to enter to get final product from rotor block one in addition when the assembling rotor, assembling is simple, is convenient to produce, safeguard.
Description of drawings
The utility model is described in further detail to utilize accompanying drawing, but the embodiment in the accompanying drawing does not consist of any restriction of the present utility model, for those of ordinary skill in the art, under the prerequisite of not paying creative work, can also obtain according to the following drawings other accompanying drawing.
Fig. 1 is the structural representation of the embodiment of a kind of brushless DC servo motor rotor of the present utility model.
Fig. 2 is the structural representation of end cap of the embodiment of a kind of brushless DC servo motor rotor of the present utility model.
Fig. 3 is the structural representation at another visual angle of the embodiment of a kind of brushless DC servo motor rotor of the present utility model.
In Fig. 1 to Fig. 3, include:
1---rotating shaft, 2---rotor block, 21---draw-in groove, 3---magnetic sheet, 31---card article, 4---end cap, 41---locating piece.
Embodiment
With the following Examples the utility model is further described.
One of embodiment of a kind of brushless DC servo motor rotor of the present utility model, as shown in Figure 1 to Figure 3, comprise rotating shaft 1, rotor block 2 and four magnetic sheets 3, described rotor block 2 is fixedly sleeved in described rotating shaft 1, described rotor block 2 is provided with draw-in groove 21, described magnetic sheet 3 is provided with the card article 31 corresponding with the draw-in groove 21 of rotor block 2, described magnetic sheet 3 and rotor block 2 clampings.Compared with prior art, be connected fasteningly between magnetic sheet 3 and the rotor, at the chucking between lower magnetic sheet 3 and the rotor block 2 that runs up, magnetic sheet 3 is difficult for producing displacement or breaks away from rotor blocks 2.So that work under the condition that rotor can be adapted at running up.Only need magnetic sheet 3 is breakked away to enter to get final product from rotor block 2 one in addition when the assembling rotor, assembling is simple.
In the present embodiment, described rotating shaft 1 two ends are connected with end cap 4, described end cap 4 be socketed on described rotating shaft 1 and with described magnetic sheet 3 mutual clampings, described end cap 4 inner faces are provided with the locating piece 41 that equates with magnetic sheet 3 quantity, described locating piece 41 is arranged at the gap between the adjacent magnetic sheet 3, described locating piece 41 and adjacent magnetic sheet 3 mutual butts.The setting of end cap 4 has avoided magnetic sheet 3 along the contingent sideslip of rotating shaft 1 direction; Simultaneously magnetic sheet 3 and end cap 4 clampings, further fixing magnetic sheet 3; And arranging of locating piece 41 can effectively avoid magnetic sheet 3 along the issuable displacement of rotor block 2 circumferencial directions.
In the present embodiment, described end cap 4 is made by stainless steel material.Because stainless steel is magnetic conduction not, therefore avoided the loss of motor magnetic flux, further improve the performance of complete machine.
