Abstract
The invention discloses a rotor punching sheet, which comprises a plurality of tooth grooves which are formed on the inner circumference of the rotor punching sheet and are used for winding a rotor coil. A tooth part is formed between every two tooth grooves. The inner circumference and the outer circumference form a yoke part. Each tooth groove comprises two semicircles. The end points of the two semicircles adjacent to the outer circumference of the punching sheet are connected through a straight section. A notch is formed between the end points of the two semicircles adjacent to the inner circumference of the punching sheet. The width of the notch is equal to the length of the straight section. The radius of the outer circumference of the rotor punching sheet is 44mm to 47mm. The radius of the inner circumference of the rotor punching sheet is 33mm to 35mm. The radium of the semicircles is 2mm to 3mm. The length of the straight sections is 2mm to 2.5mm. By reasonably designing the number, the dimension and the shape of the tooth grooves of the rotor punching sheet, since each tooth groove consists of the two semicircles and the straight section, the tooth groove is enabled to be closer to the design of a circle, the coil and the tooth parts can be fully contacted in a winding way, and not only can more copper wires be conveniently embedded, but also the improvement of the efficiency of a motor is facilitated.
Description
Technical field
The present invention relates to blower motor, particularly a kind of blower motor rotor punching.
Background technology
Present blower motor rotor punching, the slot form of its winding around, size all are arbitrarily designs, we learns through use test, its performance all has nothing in common with each other, the difference each other that has is little, and the then difference that has is very big, and tracing it to its cause is because layout is reasonable inadequately, not only operation has brought difficulty to lambda line, but also can cause the motor overall performance to descend.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, provides a kind of slot form, size design reasonable, and can improve the rotor punching of motor performance.
Technical scheme of the present invention is achieved in that
A kind of rotor punching, comprise that several are formed on the teeth groove in order to the winding rotor coil on the rotor punching inner rim, form tooth portion between teeth groove and the teeth groove, inner rim and neighboring form yoke portion, described teeth groove comprises two semicircles, the end points that closes on the punching neighboring of two semicircles links to each other by a straightway, form notch between the end points that closes on the punching inner rim of two semicircles, the width of notch is identical with the length of straightway, the radius of described rotor punching neighboring is 44～47mm, the radius of described rotor punching inner rim is 33～35mm, and the radius of semicircle is 2～3mm, and the length of straightway is 2～2.5mm.
As preferably, on the inner rim of rotor punching, be distributed with 22 teeth groove.
As preferably, the radius of described rotor punching neighboring is 45mm, and the radius of described rotor punching inner rim is 34mm, and the radius of semicircle is 2.5mm, and the length of straightway is 2.3mm.
Adopted the invention has the beneficial effects as follows of technique scheme:
The teeth groove of rotor punching of the present invention has passed through the appropriate design to number, size, shape, teeth groove adds the straight line section by two semicircles and forms, make it more approach circular design, make coil contact more abundant with the winding of tooth portion, not only can conveniently embed more copper cash, also help the raising electric efficiency.
Description of drawings
Fig. 1 is the structural representation of rotor punching of the present invention;
Fig. 2 is the structural representation of the single teeth groove of punching among Fig. 1.
Embodiment
The specific embodiment of the present invention is as follows:
Embodiment: a kind of rotor punching, as shown in Figure 1, comprise 22 teeth groove 1 that are formed on the rotor punching inner rim in order to the winding rotor coil, form tooth portion 2 between teeth groove and the teeth groove, inner rim and neighboring form yoke portion 3, as shown in Figure 2, described teeth groove 1 comprises two semicircles 4, the end points that closes on the punching neighboring of two semicircles 4 links to each other by a straightway 5, forms notch 6 between the end points that closes on the punching inner rim of two semicircles 4, and the width of notch 6 is identical with the length of straightway 5.
The radius of described rotor punching neighboring is 45mm, and the radius of described rotor punching inner rim is 34mm, and the radius of semicircle 4 is 2.5mm, and the length of straightway 5 is 2.3mm.
