Abstract
The utility model discloses a rotor sheet, comprising a plurality of tooth sockets which are formed on the inner periphery of the rotor sheet for winding a rotor coil, wherein tooth parts are formed between the tooth sockets, and yoke parts are formed by the inner periphery and the outer periphery; each of the tooth sockets comprises two semicircles, the end points of the two semicircles near the outer periphery of the sheet are connected through a straight line section, notches are formed between the end points of two semicircles near the inner periphery of the sheet, and the width of the notch is equal to the length of the straight line section; and the radius of the outer periphery of the rotor sheet is 44-47mm, and the radius of the inner periphery of the rotor sheet is 33-35mm, the radius of each semicircle is 2-3mm, and the length of the straight line section is 2-2.5mm As the tooth sockets of the rotor sheet are reasonably designed in number, dimension and shape, and each tooth socket consists of two semicircles and one straight line section, the design of the tooth socket is close to the circular design to ensure complete winding contact of the coil and the tooth parts, so that more copper wires can be embedded, and the efficiency of the motor is beneficially improved.
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, and 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 the deficiency that exists in the above-mentioned 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 comprises 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, and described teeth groove comprises two semicircles, and the end points that closes on the punching neighboring of two semicircles links to each other through 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, and the radius of described rotor punching neighboring is 44～47mm, and the radius of described rotor punching inner rim is 33～35mm; 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; It is more abundant that coil is contacted with the winding of tooth portion, not only can conveniently embed more copper cash, also helps 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
Embodiment of the present invention is following:
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, and be 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 through 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.
