Abstract
The utility model discloses a stator punching sheet used for an AC permanent-magnet servomotor. The stator punching sheet used for the AC permanent-magnet servomotor includes a punching sheet body. The punching sheet body is provided with stator teeth separated by stator grooves. Auxiliary grooves are arranged in teeth faces of the stator teeth. The auxiliary grooves are rectangular grooves, triangular grooves or semicircular grooves. Compared with the prior art, a motor adopting the stator punching sheet used for the AC permanent-magnet servomotor in the utility model positions accurately in a condition of instantly stopping. It mainly attributes to that two auxiliary grooves are increased in each of the teeth of stator punching sheet cavities in design. The auxiliary grooves are designed according to a calculation of magnefore finite element software. A comparison is made between a condition of adopting the auxiliary grooves and a condition of not adopting the auxiliary grooves. That 65.30 percents of teeth groove pulse can be reduced after the auxiliary grooves are adopted is found. The stator punching sheet used for the AC permanent-magnet servomotor has advantages of small pulse and reliable positioning.
Description
Technical field
The utility model relates to a kind of alternating-current permanent-magnet servo motor stator punching structure, and it is applicable to occasions such as industrial sewing machines, air blast, vacuum pump.
Technical background
At present 12 grooves or the 15 groove stator distributed winding rule structures of adopting of stator structure more; The required rule employee of this structure is more, has increased the difficulty of recruiting the employee of enterprise, is difficult to improve the quality and the split run output of product simultaneously; What is more important, the motor slot effect is obvious, and during momentary power failure, the rotor location is not accurate.
Summary of the invention
The utility model technical problem to be solved is the deficiency to above-mentioned prior art, and the stator punching that is used for AC permanent magnetic servo motor of a kind of motor accurate positioning under instantaneous stall is provided.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of stator punching that is used for AC permanent magnetic servo motor comprises the punching body, and the punching body is provided with by the isolated stator tooth of stator slot, it is characterized in that: on the flank of tooth of described stator tooth, offer auxiliary tank.
Described auxiliary tank is rectangular channel, triangular groove or half slot.
The width of described rectangular channel is 2mm, and the degree of depth is 0.5mm～1.5mm.
Said stator tooth is six, and the auxiliary tank on single stator tooth is two.
Compared with prior art, the beneficial effect of the utility model is:
1, the stator six groove completely circular structures of the utility model employing adopt the numerical control filament winder coiling, have improved per unit area yield, and can solve the enterprise staff breach rapidly, have improved the quality of product and the competitiveness in market simultaneously; The big problem of end winding that exists when reducing the distributed winding rule simultaneously reduces the copper consumption of whole motor, has practiced thrift production cost;
2, in the motor processed of this stator punching under the situation of instantaneous stall accurate positioning, increase by two auxiliary tanks on each tooth at the stator punching inner chamber when mainly being when design at stator punching; This auxiliary tank is through the calculating of magnefore finite element software; Before adopting auxiliary tank, carry out comparative analysis behind the auxiliary tank that adopts; Can weaken 65.30% of teeth groove pulsation after finding to adopt auxiliary tank; Simultaneously rectangular channel, triangular groove, the groove depth of three kinds of schemes of half slot, groove width in the auxiliary tank are carried out finite element analysis, wherein rectangular channel it to weaken teeth groove pulsation the strongest; And adopting the triangular form auxiliary tank can weaken a little less than the teeth groove pulsation, semi-round groove falls between; The width of rebate of auxiliary tank is the width of the notch of stator punching to the maximum, and the degree of depth of service notch weakens the best results of teeth groove pulsation during for 1mm.

Embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated:
A kind of stator punching that is used for AC permanent magnetic servo motor comprises the punching body, and the punching body is provided with by the isolated stator tooth of stator slot; In the present embodiment, stator tooth is six, on the flank of tooth of stator tooth, offers at least one auxiliary tank; In the present embodiment, the quantity of auxiliary tank is two, and auxiliary tank is the groove of rectangular channel, triangular groove half slot or other shapes; When adopting rectangular channel, the optional 1.5～2.5mm of the width of groove, the optional 0.5mm～1.5mm of the degree of depth.When width is 2mm, when the degree of depth was 1mm, pulsation was minimum, locatees the most reliable.Specifically referring to Fig. 2-8, motor teeth groove pulsating torque: 0.043Nm when not having auxiliary tank; Motor teeth groove pulsating torque: 0.0140Nm when auxiliary tank is rectangular channel; Motor teeth groove pulsating torque: 0.0144Nm when auxiliary tank is semi-circular groove; Motor teeth groove pulsating torque: 0.0189Nm when auxiliary tank is vee gutter; The weakening ratio is: 1, rectangular channel: 67.44%; Half slot: 66.51%; Vee gutter: 56.05%.It is best when so auxiliary tank is rectangular channel.
Adopt this a kind of AC permanent magnetic servo motor stator punching, it has the teeth groove of the coiling standard of numerical control filament winder, has reduced the copper consumption of separate unit motor, has reduced the production cost of separate unit motor; It is little to have pulsation simultaneously, locatees reliable advantage.
