Abstract
The utility model relates to a kind of rotor, especially a kind of anti-expanding rotor.This rotor comprises rotating shaft, iron core and magnet steel, rotating shaft is provided with iron core, and magnet steel is placed between iron core, and iron core is placed in protective cover, roller bearing is movably connected in upper and lower two ends in protective cover, two roller bearings are held in centre iron core clamp, and protective cover is provided with louvre, and this rotor can make structure more firm, thus be not easy expansion, extend the useful life of rotor, saved cost, improve effect.
Description
Technical field
The utility model relates to a kind of rotor, especially a kind of anti-expanding rotor.
Background technology
Usually, the spinning solution of motor is all the interphase interaction of the induced field produced by the rotating magnetic field produced in the stator and rotor, rotor often will run up, because it is easy in High Rotation Speed because the impact of centrifugal force, rotor core is expanded, thus affects the normal operation of motor.
Utility model content
Hold expansive deficiency to overcome existing rotor, the utility model provides a kind of anti-expanding rotor.
The utility model solves the technical scheme that its technical problem adopts: a kind of anti-expanding rotor, comprise rotating shaft, iron core and magnet steel, rotating shaft is provided with iron core, and magnet steel is placed between iron core, and iron core is placed in protective cover.
According to another embodiment of the present utility model, comprise roller bearing further and be movably connected in upper and lower two ends in protective cover, two roller bearings are held in centre iron core clamp.
According to another embodiment of the present utility model, comprise protective cover further and be provided with louvre.
The beneficial effects of the utility model are, this rotor can make structure more firm, thus is not easy expansion, extends the useful life of rotor, has saved cost, improve effect.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is a kind of structural representation of anti-expanding rotor;
1. rotating shafts, 2. iron core, 3. magnet steel, 4. protective cover, 5. roller bearing, 6. louvre in figure.
Embodiment
As the structural representation that Fig. 1 is a kind of anti-expanding rotor, a kind of anti-expanding rotor, comprise rotating shaft 1, iron core 2 and magnet steel 3, rotating shaft 1 is provided with iron core 2, magnet steel 3 is placed between iron core 2, and iron core 2 is placed in protective cover 4, and roller bearing 5 is movably connected in upper and lower two ends in protective cover 4, two roller bearings 5 are clamped in centre iron core 2, and protective cover 4 is provided with louvre 6.
First iron core 2 is placed in protective cover 4, then protective cover 4 and iron core 2 are passed in rotating shaft 1, roller bearing 5 in protective cover 4 is clamped in centre iron core 2, and when iron core starts to rotate, roller bearing 5 can make friction reduce to minimum when keeping iron core 2 not expand, and the louvre 6 on protective cover 4 can prevent temperature of rotor too high, this rotor can make structure more firm, thus is not easy expansion, extends the useful life of rotor, save cost, improve effect.
