Abstract

The present utility model provides a rotor which comprises a shaft core, a magnet, an iron core, an end plate and a fastening piece. The iron core is provided with a tooth socket, the magnet is arranged inside the tooth socket of the iron core, the shaft core passes through the iron core, the end plate is provided with an inner hole, the shaft core is fixedly connected with the end plate after passing through the inner hole of the end plate, and the end plate is pressed on two ends of the iron core and fixedly connected with the iron core through the fastening piece. The rotor is low in costs, small in magnetic leakage and stable in operation.

Description

Rotor

Technical field

The utility model relates to a kind of rotor, relates in particular to a kind of stable rotor.

Background technology

Conventional rotors generally includes iron core and is arranged at the magnetite of iron core, and along the axial arranging of iron core, torque suspension influences magnetite when causing rotor rotation usually, and is unstable when causing the rotor low cruise.

The utility model content

In order to overcome the deficiency of above-mentioned prior art, the utility model provides a kind of rotor, comprises a core, magnetite, iron core, end plate and securing member; Said iron core is provided with teeth groove; Said magnetite is arranged in the teeth groove of said iron core, and said axle core is arranged in the said iron core, and said end plate is provided with endoporus; Said axle core is arranged in the endoporus of said end plate and is fixedly connected on said end plate, and said end plate pressure holding is fixedly connected on said iron core in said iron core two ends and through securing member.

Further being improved to of the utility model is provided with the gap between said iron core and the axle core.

Further being improved to of the utility model is filled with the non-magnetic material in the gap between said iron core and the axle core.

Further being improved to of the utility model, said magnetite adopts ferrite.

Further being improved to of the utility model, said end plate adopt non-magnetic conduction substance to process.

Further being improved to of the utility model, said iron core is axially arranged with the multiple sets of teeth groove along it, and said multiple sets of teeth groove is along its axial interlaced setting.

Compared to prior art, the magnetite of the rotor of the utility model adopts ferrite, and cost is low.Iron core is not that directly contact is connected with the axle core, keeps enough air gaps between them, reduces leakage field thereby the minimizing magnetic circuit flows through a core.End plate is fastening by passing pin and end plate unshakable in one's determination, and end plate adopts non-magnetic conduction substance to process, and magnetic field can not arrive iron core through end plate and form closed magnetic loop, reduces leakage field, and end plate is that interconnect function is the effect of transmission power simultaneously.Teeth groove 151 on the iron core adopts positive and negative dislocation certain angle, and the teeth groove of a plurality of iron cores overcomes the negative effect of cogging torque along its axial interlaced setting in the rotor slow-speed of revolution a magnetic pole, reaches the stable operation effect.

Description of drawings

Fig. 2 is the decomposing schematic representation of the utility model rotor.

Embodiment

Below in conjunction with description of drawings and embodiment the utility model is further specified.

See also Fig. 1 and Fig. 2, the utility model provides a kind of rotor 10, comprises a core 11, magnetite 13, iron core 15, end plate 17 and securing member 19.Iron core 15 is cylindrical, which is provided with teeth groove 151, and in the present embodiment, iron core 15 evenly is provided with six teeth groove 151 around its axle center, and teeth groove 151 axially connects iron core 15 along iron core 15.Also be provided with fastener hole 153 on the iron core 15.Magnetite 13 is provided with and is fastened in the teeth groove 151 of said iron core 15, and magnetite 13 adopts ferrite.Iron core 15 is axially arranged with multiple sets of teeth groove 151 along it, and said multiple sets of teeth groove 151 is along its axial interlaced setting.

End plate 17 is circular, which is provided with connecting hole 171 and endoporus 173.Axle core 11 wears and is fixedly connected on the endoporus 173 of end plate 17, is provided with the gap between iron core 15 and the axle core 11.Gap between iron core 15 and the axle core 11 is provided with the non-magnetic material.End plate 17 pressure holdings are in said iron core 15 two ends.Securing member 19 is arranged in the connecting hole 171 of end plate 17 and the fastener hole 153 of iron core 15, and end plate 17 and iron core 15 are interfixed, and end plate 17 materials adopt non-magnetic conduction substance, process like materials such as stainless steels.

The magnetite 13 of the rotor 10 of the utility model adopts ferrite, and cost is low.Iron core 15 is not that directly contact is connected with axle core 11, keeps enough air gaps between them, reduces leakage field thereby the minimizing magnetic circuit flows through a core 11.End plate 17 is fastening by passing pin and end plate 17 unshakable in one's determination, and end plate 17 adopts non-magnetic conduction substance to process, and magnetic field can not arrive iron core 15 through end plate 17 and form closed magnetic loop, reduces leakage field, and end plate 17 is that interconnect function is the effect of transmission power simultaneously.Teeth groove 151 on the iron core 15 adopts positive and negative dislocation certain angle, and the teeth groove 151 of a plurality of iron cores 15 overcomes the negative effect of teeth groove 151 torques along its axial interlaced setting in rotor 10 slow-speed of revolution a magnetic pole, reaches the stable operation effect.

Above content is the further explain that combines concrete preferred implementation that the utility model is done, and can not assert that the practical implementation of the utility model is confined to these explanations.For the those of ordinary skill of technical field under the utility model, under the prerequisite that does not break away from the utility model design, can also make some simple deduction or replace, all should be regarded as belonging to the protection range of the utility model.
