Abstract
The invention belongs to the technical field of motor devices, and relates to a permanently-magnetic rotor. The permanently-magnetic rotor comprises a mandrel, a magnetic core, permanent magnets and an elastic bushing. The magnetic core is arranged on the outer portion of the mandrel, the permanent magnets are arranged on one side of the magnetic core, and the elastic bushing is arranged between the mandrel and the magnetic core. The permanent magnets are fixedly connected with the magnetic core through non-magnetic fastening pieces. The permanently-magnetic rotor is simple, compact and reasonable in structure, convenient and quick to assemble and reliable in connection, mechanical strength of the rotor is increased, starting performance of a motor is improved, vibration is reduced, noise is low, the service life of the rotor is prolonged, reliability of the rotor is greatly improved, and application and popularization are facilitated.
Description
Technical field
The present invention relates to a kind of technical field of electric machine, especially a kind of p-m rotor.
Background technology
Existing rotor is because so rigidity combination produces vibration easy, and noise is larger, and, processing request precision is high, processing difficulties, and manufacturing cost is high, simultaneously, permanent magnet easily comes off, and has shortened the useful life of rotor, greatly reduces the operational reliability of rotor.
Summary of the invention
In order to overcome, existing rotor oscillation and noise are larger, processing difficulties, manufacturing cost is high, useful life is short and reliability is low deficiency, the invention provides a kind of p-m rotor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of p-m rotor, comprise mandrel, magnetic conductive core, permanent magnet and resilient bushing, mandrel outside is provided with magnetic conductive core, and magnetic conductive core one side is provided with permanent magnet, between mandrel and magnetic conductive core, is provided with resilient bushing.
According to another embodiment of the invention, further comprise that permanent magnet is fixedly connected with magnetic conductive core by securing member.
According to another embodiment of the invention, further comprise that securing member is non magnetic securing member.
The invention has the beneficial effects as follows, this permanent magnet rotor structure is simple, compact and reasonable, easy to assembly quick, connect reliably, strengthened the mechanical strength of rotor, improved the starting performance of motor, reduced vibration, noise is smaller, has extended the useful life of rotor, greatly improved the reliability of rotor, be easy to use and promote.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
1. mandrels in figure, 2. magnetic conductive core, 3. permanent magnet, 4. resilient bushing, 5. securing member.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of p-m rotor, comprise mandrel 1, magnetic conductive core 2, permanent magnet 3, resilient bushing 4 and securing member 5, mandrel 1 outside is provided with magnetic conductive core 2, magnetic conductive core 2 one sides are provided with permanent magnet 3, between mandrel 1 and magnetic conductive core 2, be provided with resilient bushing 4, permanent magnet 3 is fixedly connected with magnetic conductive core 2 by securing member 5, and securing member 5 is non magnetic securing member.
During use, there is magnetic conductive core 2 mandrel 1 outside, between mandrel 1 and magnetic conductive core 2, be provided with resilient bushing 4, vibration is reduced, thereby reduced noise, magnetic conductive core 2 one sides are provided with permanent magnet 3, permanent magnet 3 is fixedly connected with by securing member 5 with magnetic conductive core 2, securing member 5 is non magnetic securing member, thus permanent magnet 3 difficult drop-offs, and assembling is reliable.This permanent magnet rotor structure is simple, compact and reasonable, easy to assembly quick, connect reliable, strengthen the mechanical strength of p-m rotor, improved the starting performance of motor, reduced vibration, noise is smaller, extended the useful life of p-m rotor, greatly improved the reliability of p-m rotor, be easy to use and promote.
