Abstract
The invention discloses a rotor sheet for a fan motor, which is in an annular shape and comprises a plurality of tooth grooves, wherein the tooth grooves are formed on the inner periphery of the rotor sheet and are used for winding rotor coils, tooth parts are formed between the tooth grooves, a yoke part is formed in a region between the inner periphery and the outer periphery of the rotor sheet, the radius of the rotor sheet is 67 to 70mm, and a plurality of ventilation holes are arranged on the yoke part. The ventilation holes are arranged on the yoke part region arranged between the inner periphery and the outer periphery of the rotor sheet, so the heat radiation performance of the rotor sheet is improved, in addition, materials are saved, the weight is reduced, and the performance of the motor is also not influenced.
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, mostly be to be annular, be provided with a plurality of teeth groove in order to winding around on the rotor punching inner rim of annular, the zone between rotor punching inner rim and neighboring is the zone that does not have vacancy, such rotor punching radiating effect is poor, and weight is also big.
Summary of the invention
The present invention has overcome above-mentioned the deficiencies in the prior art, and a kind of good heat dissipation effect is provided, and weight is little, the blower motor rotor punching of economical with materials.
Technical scheme of the present invention is achieved in that
A kind of blower motor rotor punching, described rotor punching is annular, 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, the inner rim of rotor punching and the zone between the neighboring form yoke portion, the radius of rotor punching is 67～70mm, is provided with a plurality of ventilation holes in yoke portion.
As preferably, on the inner rim of rotor punching, be distributed with 30 teeth groove.
As preferably, described ventilation hole is rounded.
Adopted the invention has the beneficial effects as follows of technique scheme:
The present invention is provided with a plurality of ventilation holes on the inner rim of rotor punching and the yoke portion zone between the neighboring, not only make the rotor punching heat-sinking capability be improved, but also saved material, alleviated weight, and motor properties is not affected yet.
Description of drawings
Fig. 1 is the structural representation of rotor punching of the present invention.
