Abstract
The utility model discloses a kind of rotor of permanent-magnetic outer rotor motor, including rotor body, rotor body includes aluminum hull, iron hoop, magnet and rotating shaft, casting aluminum hull are while embedded iron hoop, iron hoop is wrapped in inside aluminum hull, and inside iron hoop, rotating shaft is pressed into aluminum hull and constitutes rotor body magnet pasting.The utility model has the advantages that：Improve the thermal diffusivity of motor；Save manufacturing process；Possesses antiseptic power, it is not necessary to carry out extra erosion shield treatment.
Description
Technical field
The utility model is related to permanent-magnetic outer rotor motor and electrical generator fields.
Background technology
The rotary power of motor be by the reciprocation in electric current produced magnetic field between rotor and stator, and by electric energy turn
It is changed to the mechanical energy of rotation.Because the permanent-magnet material of new magnetic conduction high is constantly developed so that the volume and weight of permanent magnet
Amount is smaller and magnetic is stronger, therefore the permanent-magnetic electric machine being made using this kind of magnetic conduction electromagnet high is with conventional wire-wound motor just
Identical torsion compares, and its volume of permanent magnet motor and weight relatively significantly reduce.
The rotor of external rotor electric machine common at present is made up of a work durm, by welding or compression joint technique and fixed rotating shaft
End be attached, permanent magnet is stained with inside work durm, this cause rotor drum need multiple tracks technique complete, simultaneously because work durm
Outer surface be very easy to corrosion, it is necessary to electrophoresis or the antirust treatment of spraying, in addition, the heat-sinking capability of this structure also compares
Difference.
Utility model content
The purpose of this utility model is to provide a kind of rotor of permanent-magnetic outer rotor motor, it is intended to reduce process costs and offer
The heat-sinking capability of rotor.
The utility model is achieved through the following technical solutions：
A kind of rotor of permanent-magnetic outer rotor motor, including rotor body, the rotor body, including aluminum hull, iron hoop, magnet
And rotating shaft, iron hoop is embedded in while casting aluminum hull, iron hoop is wrapped in aluminum hull inner magnet and is pasted onto inside iron hoop, rotating shaft press-in aluminium
Shell and constitute rotor body.
Further, the iron hoop it is cylindrical on have cast aluminium space, cast aluminium space is hole or groove.
Further, the end of the aluminum hull is designed with the size hole with rotating shaft interference fit.
Further, the magnet pasting produces magnetic conduction loop inside iron hoop.
The beneficial effects of the utility model are：The radiating of the beneficial motor of structure of full aluminum hull；Aluminum hull, iron hoop, end axis hole
Completed by the step of aluminium die casting one, save manufacturing process；The cylindrical of iron hoop makes some cast aluminium energy by modes such as punching, grooves
Enough spaces for flowing into so that iron hoop is completely fixed on aluminum hull, will not be rotated；Outside the material of the aluminium alloy that aluminum hull is used
Surface has antiseptic power, it is not necessary to carry out extra erosion shield treatment.
Brief description of the drawings
Fig. 1 is that schematic diagram is dissected in front of the present utility model
Fig. 2 is structural representation of the present utility model
Wherein：1st, aluminum hull, 2, iron hoop, 3, magnet, 4, rotating shaft, 5, size hole.
Specific embodiment
As shown in Figures 1 and 2, the utility model mainly teaches the rotor of permanent-magnetic outer rotor motor by aluminum hull 1, iron hoop 2,
Magnet 3 and rotating shaft 4 are constituted, and are embedded in iron hoop 2 while casting aluminum hull 1, it is not necessary to multiple tracks technique, save process costs, aluminum hull 1
Structure is relatively beneficial to the radiating of motor and aluminum alloy materials have certain antiseptic power, it is not necessary to carry out extra anticorrosion again
Coating treatment, iron hoop 2 is wrapped in inside aluminum hull 1, for ensure iron hoop 2 in aluminum hull 1 have certain intensity, iron hoop 2 it is cylindrical
The space that some cast aluminiums can be flowed into can be made by modes such as punching, grooves, so that iron hoop 2 is completely fixed on aluminum hull 1,
Will not rotate, magnet 3 is pasted onto on the iron hoop of magnetic conduction, the magnetic conduction loop that magnet 3 can be produced to need, the end of aluminum hull 1 sets
The size hole 5 of the interference fit that rotating shaft 4 can be pressed into is counted out, rotating shaft 4 can be by pressure press-in cooperation hole, so as to be fixed on aluminium
On shell 1.
Above-described embodiment only illustrative principle of the present utility model, and the embodiment that part uses, for book
The technical staff in field designs similar technical scheme under the inspiration of technical solutions of the utility model, and reaches above-mentioned skill
The effect of art, belong to protection domain of the present utility model.
