Abstract
The invention relates to the technical field of motor devices, in particular to a motor rotor which comprises a rotating shaft, magnetic strips and a sleeve. The magnetic strips are arranged outside the rotating shaft and externally wrapped by the sleeve, a groove is formed between the magnetic strips, and projections are arranged on the inner side of the sleeve and are non-magnetic strips. The motor rotor is simple, compact and reasonable in structure, convenient and rapid to assemble and reliable in connection, the magnetic strips are reliably mounted and cannot fall off, partial flux leakage is avoided when the magnetic strips cling together, the service life of the motor rotor is prolonged, reliability of the motor rotor is greatly improved, and the motor rotor is easy to use and popularize.
Description
Technical field
The present invention relates to a kind of technical field of electronic device, especially a kind of motor rotor.
Background technology
The magnet steel of existing motor rotor abuts against together the easily phenomenon of generating portion leakage field, affects the magnetic field intensity in main flux loop, and magnet steel easily comes off, and has shortened the useful life of motor rotor, greatly reduces the reliability of motor rotor.
Summary of the invention
In order to overcome the easy leakage field of existing motor rotor, useful life is short and reliability is low deficiency, the invention provides a kind of motor rotor.
The technical solution adopted for the present invention to solve the technical problems is: a kind of motor rotor, comprise rotating shaft, magnetic stripe and sleeve, and rotating shaft outside is provided with magnetic stripe, and magnetic stripe outer wrap has sleeve.
According to another embodiment of the invention, further comprise between magnetic stripe and be provided with groove, sleeve inner side is provided with projection.
According to another embodiment of the invention, further comprise that projection is for non magnetic strip shape body.
The invention has the beneficial effects as follows, this motor rotor structure is simple, compact and reasonable, easy to assembly quick, connect reliably, magnetic stripe is installed reliable, avoids occurring the phenomenon that magnetic stripe comes off, and avoided magnetic stripe to abut against the phenomenon of generating portion leakage field together, extended the useful life of motor rotor, greatly improved the reliability of motor 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. rotating shafts in figure, 2. magnetic stripe, 3. sleeve, 4. groove, 5. projection.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of motor rotor, comprises rotating shaft 1, magnetic stripe 2, sleeve 3, groove 4 and projection 5, rotating shaft 1 outside is provided with magnetic stripe 2, and magnetic stripe 2 outer wrap have sleeve 3, are provided with groove 4 between magnetic stripe 2, sleeve 3 inner sides are provided with projection 5, and projection 5 is non magnetic strip shape body.
During use, magnetic stripe 2 is fixed in rotating shaft 1, between each magnetic stripe 2, forms groove 4, and there is projection 5 sleeve 2 inner sides, and projection 5 is non magnetic strip shape body, and projection 5 coordinates with groove 4, and sleeve 3 is enclosed within the outside of magnetic stripe 2.This motor rotor structure is simple, compact and reasonable, easy to assembly quick, connect reliable, magnetic stripe is installed reliable, avoid the phenomenon that magnetic stripe comes off occurs, and avoided magnetic stripe to abut against the phenomenon of generating portion leakage field together, extended the useful life of motor rotor, greatly improved the reliability of motor rotor, be easy to use and promote.
