Abstract
The utility model discloses a kind of stator punching of magneto, comprise the punching body of annular, described punching body inner periphery distributes some stator tooths, described stator tooth distributes some stator slots, described stator slot comprises the notch of rectangle and circular bottom land, and described bottom land is positioned at pocket bottom and crossing with notch.The program, by arranging rational stator slot shape, realizes the effect better suppressing cogging torque.
Description
Technical field
The utility model relates to a kind of stator punching of magneto, belongs to field of motor manufacturing.
Background technology
Magneto is applied more and more extensive in high performance control system, but permanent magnet and slotted core interact, and produces cogging torque, causes vibration & noise.As the effective cogging torque suppressor mode of one, stator tooth fluting receives the concern of people.Do the shape of stator slot various in existing research respectively, comprise rectangle, semicircle vee gutter, surface rectangle groove is best to suppressing the effect of cogging torque, and be secondly half slot, triangular groove effect is the poorest.But this research is confined to the discussion of simple shape, does not continue to inquire into some complicated shapes and whether to suppression cogging torque, there is better effect.
Utility model content
The purpose of this utility model is the stator punching providing a kind of magneto, by arranging rational stator slot shape, realizes the effect better suppressing cogging torque.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of stator punching of magneto, comprise the punching body of annular, described punching body inner periphery distributes some stator tooths, described stator tooth distributes some stator slots, described stator slot comprises the notch of rectangle and circular bottom land, and described bottom land is positioned at pocket bottom and crossing with notch.
Preferably, described stator slot is symmetrically distributed on described stator tooth.
Preferably, described width of rebate is equal with described bottom radius.
Preferably, described width of rebate is 1/1 to five/4th of described stator tooth top width, and the degree of depth of described stator slot is 1/1 to three/2nd of described stator tooth top width.
Preferably, adjacent described stator tooth is formed with winding slot, and be semicircle bottom described winding slot, described winding slot top forms a gap by parallel two sides, and the width of described gap is 4/3 to five/5ths of winding slot bottom radius.
By adopting such scheme, the notch of rectangle is crossing with notch to the basis suppressing cogging torque to have a better effects arranges circular bottom land at pocket bottom in the prior art, because bottom land is circular, there is each diversity in the line of magnetic induction that all directions are come in, thus mutually cut conflict, the cogging torque produced is weakened further, makes motor overcome the minimizing of the energy ezpenditure on cogging torque, improve the useful work of motor, reduce energy consumption.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is structure chart of the present utility model;
Fig. 2 is the enlarged drawing at A place in the utility model Fig. 1.
Reference numeral: 1, punching body; 2, stator tooth; 3, stator slot; 3a, notch; 3b, bottom land; 4, winding slot.
Embodiment
A kind of stator punching of magneto, comprise the punching body 1 of annular, punching body 1 external diameter is 175mm, internal diameter is 120mm, punching body 1 inner periphery distributes 48 stator tooths 2, stator tooth 2 distributes two symmetrical stator slots 3, and stator slot 3 comprises the notch 3a of rectangle and circular bottom land 3b, bottom land 3b and to be positioned at bottom notch 3a and crossing with notch 3a.The notch 3a of rectangle is crossing with notch 3a to the basis suppressing cogging torque to have a better effects being arranged bottom notch 3a circular bottom land 3b in the prior art, because bottom land 3b is circular, there is each diversity in the line of magnetic induction that all directions are come in, thus mutually cut conflict, the cogging torque produced is weakened further, making motor overcoming the minimizing of the energy ezpenditure on cogging torque, improve the useful work of motor, reducing energy consumption.
Wherein, notch 3a width is equal with bottom land 3b radius.When notch 3a width is equal with bottom land 3b radius, suppress cogging torque to reach a peak value, energy-saving effect is best.
Wherein, notch 3a width is 1/1 to five/4th of stator tooth 2 top width, and the degree of depth of stator slot 3 is 1/1 to three/2nd of stator tooth 2 top width.Along with stator slot 3 depth down, inhibition is more obvious, but too dark then stator tooth 2 intensity is affected, and same width range is also based on this, and in above-mentioned scope, intensity and energy-saving effect reach balance.
Wherein, adjacent described stator tooth 2 is formed with winding slot 4, and winding slot 4 end 3b portion is semicircle, and winding slot 4 top forms a gap by parallel two sides, and the width of gap is 4/3 to five/5ths of winding slot 4 end 3b portion radius.Gap bore diminishes within the specific limits can increase the magnetic flux density of motor, and improve electric efficiency, when the width of gap is 0.75 with the ratio of winding slot 4 end 3b portion radius, reach a peak value, now electric efficiency is the highest.
