Description
[technical field]
The present invention relates to a kind of high-speed rotary motor rotor arrangement.
[background technology]
Existing high-speed rotary motor, particularly environment for use is abominable, vibrates in the large situation, and its epitrochanterian magnet can split under the large effect of centrifugal force, motor straight is informed of a case useless.Have again, the rotor of high speed rotating, greatly also may there be skidding in magnet and rotor torque.
The present invention is making in such cases.
[summary of the invention]
The objective of the invention is to have overcome the deficiencies in the prior art, a kind of High Rotation Speed armature spindle is provided, magnet does not ftracture, the high-speed rotary motor rotor arrangement that result of use is good durable.
Another object of the present invention has provided a kind of durable, the motor that result of use is good.
For solving the problems of the technologies described above, the present invention by the following technical solutions:
The high-speed rotary motor rotor arrangement is characterized in that including armature spindle 1, is arranged with rotor magnet 2 at armature spindle 1, is arranged with rigidized cover 3 at described rotor magnet 2.
Aforesaid high-speed rotary motor rotor arrangement is characterized in that described rigidized cover 3 inner surfaces are pressed on the outer surface of rotor magnet 2, are respectively equipped with the end face meson 4 that blocks rotor magnet 2 both ends of the surface at the two ends of rigidized cover 3.
Aforesaid high-speed rotary motor rotor arrangement is characterized in that described rigidized cover 3 is magnetic conductive metal body not.
Aforesaid high-speed rotary motor rotor arrangement is characterized in that described not magnetic conductive metal body is stainless steel, copper.
Aforesaid high-speed rotary motor rotor arrangement is characterized in that described rotor magnet 2 forms for the manufacturing of sintered NdFeB material.
A kind of adjustment electric rotating machine, it is characterized in that including motor casing 5, be provided with stator module at motor casing 5 inner surfaces, in motor casing 5, also be provided with armature spindle 1, be arranged with rotor magnet 2 at armature spindle 1, be arranged with rigidized cover 3 at described rotor magnet 2, be provided with separately bearing 6 and bearing cap 7 at the forward and backward two ends of motor casing 5, described armature spindle 1 is arranged on the bearing 6.
Aforesaid adjustment electric rotating machine is characterized in that described stator module includes the silicon steel sheet 8 that is fastened on successively in the motor casing 5, insulating paper 9, coiling 10.
Aforesaid adjustment electric rotating machine is characterized in that described armature spindle 1 stretches out motor casing 5 outer ends and also is provided with fan blade 11.
The present invention compared with prior art has following advantage:
The present invention is arranged with rigidized cover at the outer surface of magnet, and armature spindle is when High Rotation Speed like this, and under the protection of rigidized cover, the magnet of its inside can not split, and under the serviceability that does not affect magnet, has realized the protection to magnet.
Two, because rigidized cover is to be set on the magnet, whole magnet is enveloped, can also prevent the problem that magnet gets rusty.
Three, because the rigidized cover inner surface is pressed on the outer surface of rotor magnet, can also prevent from skidding between magnet and the armature spindle, add high pulling torque.
Four, the present invention has adopted the sintered NdFeB material to make magnet, has also that volume is little, power is large, heatproof is high, acid-proof, and alkali prevention, grease proofing.
[description of drawings]
Fig. 1 is exploded view of the present invention;
Fig. 2 is stereogram of the present invention.
[embodiment]
