The utility model discloses a round bottom groove of first circular arc and the platykurtic between the second straight line combine, have reduced rotor punching's magnetic leakage, and it is even to make magnetic flux distribute, makes the work efficiency of motor improve 10%, has reduced the volume of using copper of motor, has reduced the manufacturing cost of motor, and rotor punching's manufacture craft is simpler, has improved the production efficiency of rotor.
Description
Technical field
Turn blower motor outside the utility model relates to, particularly relate to a kind of motor rotor punching sheet.
Background technology
The current outer rotor punching turning blower motor, the slot form of its winding around is all flat-bottom slot, and groove number is 22 grooves, the design of teeth groove size and shape is all more random, learn after tested, the shape of teeth groove and size affect the distribution of magnetic circuit, the shape of teeth groove is unreasonable, cause magnetic circuit irrational distribution, easily cause magnetic circuit supersaturation, the heat production improving rotor causes temperature of rotor to raise, add the unsteadiness of rotor, cause electronics to produce vibration and noise, reduce the operating efficiency of motor, improve the energy consumption of motor.
Summary of the invention
The utility model is unreasonable for teeth groove design in prior art, and the shortcomings such as motor is unstable, inefficiency, and energy consumption of electrical machinery is high, provide a kind of teeth groove reasonable in design, motor stabilizing, operating efficiency is high, the rotor punching that energy consumption of electrical machinery is low.
In order to solve the problems of the technologies described above, the utility model is solved by following technical proposals:
A kind of rotor punching, comprise inner edge and outside, yoke portion is formed between inner edge and outside, the yoke portion closing on inner edge side is provided with multiple teeth groove, teeth groove comprises the first circular arc closing on outside and the notch closing on inner edge, the two-end-point of notch is respectively equipped with outward extending first straight line in both sides, is provided with the second straight line, is provided with the second circular arc between the second straight line and the first straight line between the first straight line and the first circular arc.Teeth groove is set as circular arc, make magnetic circuit can along circular arc smooth flow, avoid magnetic circuit to be stuck in angled corner, cause magnetic circuit obstructed, improve the energy consumption of motor, reduce the operating efficiency of motor, and it is large to form local flux amount in corners, causes the temperature in corner to raise, adds the unsteadiness of motor, make motor oscillating and produce noise, affecting the useful life of motor.
As preferably, the angular range of the first straight line and notch is between 70 ° ~ 120 °, and the angular range of the first straight line and the second straight line is between 90 ° ~ 115 °.By the design become more meticulous to angle, guarantee that magnetic circuit can be unobstructed, ensure that magnetic flux is uniformly distributed on rotor punching.
As preferably, the diameter of outside is between 88 ~ 94mm.
As preferably, uniformly on inner edge be arranged with 26 ~ 32 teeth groove.By increasing the design of teeth groove, ensure that the radian of the first circular arc, avoiding magnetic flux adding up in corner, cause temperature to raise the energy consumption that improve motor, decrease magnetic leakage simultaneously, improve the efficiency of motor.
As preferably, the two ends of the second straight line respectively with the first circular arc and the second circular arc tangent.By the combination of flat between the first circular arc and the second straight line, decrease magnetic leakage, reduce the energy consumption of motor, by tangent, avoid forming obtuse angle between circular arc and the second straight line, cause magnetic circuit obstructed, reduce the efficiency of motor.
The utility model is owing to have employed above technical scheme, there is significant technique effect: be combined by the flat of round bottomed vessel between the second straight line of the first circular arc, decrease the magnetic leakage of rotor punching, make magnetic flux distributions even, make the operating efficiency of motor improve 10%, decrease the copper consumption of motor, reduce the production cost of motor, the manufacture craft of rotor punching is simpler, improves the production efficiency of rotor.
