Abstract
The utility model discloses a rotor punching. The rotor punching comprises a rotor punching body, and the periphery of the rotor punching body is evenly and annularly equipped with the tooth sockets used for winding rotor coils. Each tooth socket comprises a groove body, and the groove body is a trapezoidal structure of which the upper part is wide and the lower part is narrow, and comprises a groove edge a and a groove edge b which are arranged left and right symmetrically. The upper ends of the groove edges a and b are bent towards middle separately and are extended outwards to form a notch, and the lower ends of the groove edges a and b are connected via a semi-circular structure to form a groove bottom. An inner ring of the rotor punching body is equipped with a clamping hole for connecting a rotating shaft, and the clamping hole is equipped with a clamping groove. The tooth sockets of the rotor punching are reasonable in number, dimension and shape design, the noise is reduced effectively, the performance of a motor is improved, and the processing and lamination are both convenient.
Description
Technical field
The utility model discloses a kind of rotor punching.
Background technology
Current rotor punching sheet of blower motor, the slot form of its winding around, size are all arbitrarily designs, we learns through use test, its performance is all different, the difference each other having is little, and the difference having is very large, and tracing it to its cause is because layout is reasonable not, not only to lambda line, operation has brought difficulty, but also can cause motor overall performance to decline.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of slot form, size design rationally and can improve the rotor punching of motor performance.
The utility model technical scheme adopting of dealing with problems is:
A kind of rotor punching, comprise rotor punching body, described rotor punching body periphery pressed on ring is established the teeth groove that is evenly equipped with to be wound around rotor coil, described teeth groove comprises groove body, the groove of described teeth groove is as trapezium structure wide at the top and narrow at the bottom, it comprises trough rim a and the trough rim b being symmetrical set, described trough rim a upper end and trough rim b upper end bend to centre respectively and the formation notch that stretches out, described trough rim a lower end and trough rim b lower end are connected to form bottom land by semicircular structure, the inner ring of rotor punching body is provided with the hole clipping of connection rotating shaft, and this hole clipping is provided with draw-in groove.
Further setting as such scheme: described teeth groove is 90～100.
The beneficial effects of the utility model are: the teeth groove of rotor punching has passed through the appropriate design to number, size, shape, effectively reduces noise, has improved motor performance, and processing and laminate all and facilitate.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the A place enlarged drawing of Fig. 1, the structural representation of major embodiment teeth groove;
Fig. 3 is the B place enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1 to Figure 3, the utility model a kind of rotor punching, it comprises rotor punching body 1, described rotor punching body 1 periphery pressed on ring is established the teeth groove 2 that is evenly equipped with to be wound around rotor coil, described teeth groove 2 comprises groove body 3, the groove body 3 of described teeth groove 2 is trapezium structure wide at the top and narrow at the bottom, it comprises trough rim a31 and the trough rim b32 being symmetrical set, described trough rim a31 upper end and trough rim b32 upper end bend to centre respectively and stretch out and form notch 4, described trough rim a31 lower end and trough rim b32 lower end are connected to form bottom land 5 by semicircular structure, the inner ring of rotor punching body 1 is provided with the hole clipping 6 of connection rotating shaft, this hole clipping 6 is provided with draw-in groove 61, on this draw-in groove 61, be also provided with the keyway 62 that can bring into play acrotorque and further play the multiple effects such as location, described teeth groove 2 is 90～100.
The teeth groove 2 of the utility model rotor punching has passed through the appropriate design to number, size, shape, effectively reduces noise, has improved motor performance, and processing and laminate all and facilitate.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection range of the claims in the present invention.
