Abstract
The utility model discloses a rotor sheet, including the lamellar body, be equipped with the shaft hole in the middle of the lamellar body, lamellar body circumference distributes there is the wire winding groove, and adjacent wire winding flute profile becomes wrapping post, characterized by: the shrink mouth that the wire winding groove includes the bar wire winding portion of extending to lamellar body center and lies in the lamellar body edge, wire winding portion and shrink mouthful intercommunication, wire winding portion width is the same everywhere, the linear distribution has a triangle -shaped barb on two lateral walls of wire winding portion, the barb with the integrative punching press of wrapping post forms. This scheme provides a rotor sheet, and structural design is more reasonable, and the coiling in the groove that winds of copper line is inseparabler, and is difficult not hard up.
Description
Technical field
The utility model relates to a kind of motor component, is a kind of rotor punching in particular.
Background technology
The mechanical strength of rotor and stiffness analysis are important steps of the high speed embedded formula magneto of design.When high speed operation of motor, the part that wrapping post between adjacent winding slot the most easily ruptures as rotor structure for permanent magnet motor, and the intensity effect of the accuracy of copper cash in winding slot to wrapping post is larger, if loosening appears in copper cash, easily in rotation process with wrapping post generation relative motion, affect the mechanical performance of wrapping post.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of rotor punching, and structural design is more reasonable, and copper cash coiling in winding slot is tightr, not easily loosens.
For achieving the above object, the utility model provides following technical scheme: a kind of rotor punching, comprise lamellar body, axis hole is provided with in the middle of lamellar body, lamellar body circumference is distributed with winding slot, adjacent winding slot forms wrapping post, it is characterized in that: described winding slot comprises the strip wound portion extended to lamellar body center and the contraction mouth being positioned at lamellar body edge, winding section is communicated with contraction mouth, winding section width is identical everywhere, two sidewall Linears of winding section are distributed with triangle barb, and barb and described wrapping post integrated punching form.
By adopting technique scheme, rotor is in high speed rotating process, and copper cash is easily outwards moved due to centrifugal action, and barb can play conflict effect, ensures the relative position of copper cash in winding slot; Barb and wrapping post integrated punching, can ensure the bonding strength of barb, avoids coming off or being out of shape.
Preferably, described contraction mouth comprises notch part and transition part, and intermediate location is between winding section and notch part, and transition part is trapezium structure, and notch part is square structure.
By adopting technique scheme, because copper cash will enter winding section through shrinking eloquence, trapezium structure facilitates copper cash to smoothly transit to winding section, and foursquare notch part can improve magnetic flux and magnetic density, and electric efficiency is higher.
Preferably, arc heat dissipation cavity is provided with bottom described winding section.
By adopting technique scheme, heat dissipation cavity is arranged on bottom winding section, and relatively near rotor center, radiating effect is obvious, and produce noise when arcuate structure ventilates low, motor rotation is more steady.
Preferably, the width of described winding section is 4.2mm.
By adopting technique scheme, the diameter of usual copper cash is at about 2mm, and the width of winding section, slightly wider than the size after two row's copper cash arrangements, retains certain interval again, achieves the object that effectively can improve again structural compactness convenient for assembly.

Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
A kind of rotor punching, comprise lamellar body 1, axis hole 3 is provided with in the middle of lamellar body 1, lamellar body 1 circumference is distributed with winding slot 2, and adjacent winding slot 2 forms wrapping post, and winding slot 2 comprises the strip wound portion 4 extended to lamellar body 1 center and the contraction mouth 5 being positioned at lamellar body 1 edge, winding section 4 is communicated with contraction mouth 5, winding section 4 width is identical everywhere, and two sidewall Linears of winding section 4 are distributed with triangle barb 6, and barb 6 and described wrapping post integrated punching form.Rotor is in high speed rotating process, and copper cash is easily outwards moved due to centrifugal action, and barb 6 can play conflict effect, ensures the relative position of copper cash in winding slot 2; Barb 6 and wrapping post integrated punching, can ensure the bonding strength of barb 6, avoid coming off or being out of shape.Winding section 4 width is identical everywhere, ensure that the coiling of copper cash in winding section 4 is even, ensure that dynamic balancing.
As shown in Figure 4, contraction mouth 5 comprises notch part 5a and transition part 5b, and transition part 5b is between winding section 4 and notch part 5a, and transition part 5b is trapezium structure, and notch part 5a is square structure.Because copper cash will just enter winding section 4 through contraction mouth 5, trapezium structure facilitates copper cash to smoothly transit to winding section 4, and foursquare notch part 5a can improve magnetic flux and magnetic density, and electric efficiency is higher.
As shown in Figure 2, arc heat dissipation cavity 7 is provided with bottom winding section 4.Heat dissipation cavity 7 is arranged on bottom winding section 4, and relatively near rotor center, radiating effect is obvious, and produce noise when arcuate structure ventilates low, motor rotation is more steady.
Wherein, the width of winding section 4 is 4.2mm.The diameter of usual copper cash is at about 2mm, and the width of winding section 4, slightly wider than the size after two row's copper cash arrangements, retains certain interval again, achieves the object that effectively can improve again structural compactness convenient for assembly.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
