Description
Technical field：
The present invention relates to a kind of cooling structure of magnetic suspension motor rotor.
Background technology：
In existing magnetcisuspension floating centrifugal motor, the open type cooling fan or external cooling fan that generally use are cold
But windage loss consumption is larger, and cooling effect is poor, and cooling effectiveness is low, and motor internal temperature is excessive, and axial sensor on magnetic bearing can be because
Temperature is excessive and scaling loss, magnetic bearing are easily damaged.
The content of the invention：
The present invention is to provide a kind of cooling of magnetic suspension motor rotor to solve the above-mentioned problems of the prior art
Structure.
The technical solution adopted in the present invention has：A kind of cooling structure of magnetic suspension motor rotor, including magnetic axis bearing, core
Axis and the enclosed cooling fan being made of fan body and fan housing body, the fan body in enclosed cooling fan are threaded in mandrel
On, fan housing body is threaded on the inner wall of magnetic axis bearing, and formed with cooling air channel between fan body and fan housing body；In mandrel
Axis direction be equipped with coolant flow channel, the coolant flow channel and cooling air channel connect.
Further, the side wall of the fan body is equipped with blade part, and fan body and blade part are integrally formed.
Further, the outer circle wall of two end of fan body stretches out and forms boss portion, the boss portion
Inner wall is ramp structure.
Further, the fan housing body is made of electric bakelite, and fan body, which is adopted, to be formed from aluminium.
Further, the side wall of the fan body is equipped with first through hole, and the second through hole is equipped with the side wall of mandrel, the
One through hole and the second through hole connect.
Further, the axial direction of the magnetic axis bearing is equipped with ventilation hole.
The present invention has the advantages that：Cooling fan of the present invention in rotor lower end uses closed type structure, solves
The problem of windage loss of open type cooling fan or external cooling fan consumption is larger, cooling wind enters magnetic axis bearing from ventilation hole, from cold
But runner enters mandrel, adds the incoming air area of cooling, by the blade part of enclosed cooling fan, will cool down wind along cooling
The direction in air passage cools down successively upwards；Cooling air channel reduces cooling windage loss consumption, increases cooling effect.
Brief description of the drawings：
Fig. 1 is structure chart of the present invention.
Fig. 2 is the structure chart between enclosed cooling fan and mandrel in the present invention.
Embodiment：
The present invention is further illustrated below in conjunction with the accompanying drawings.
Such as Fig. 1 and Fig. 2, the present invention discloses a kind of cooling structure of magnetic suspension motor rotor, including magnetic axis bearing 1, mandrel 2
And the enclosed cooling fan 6 being made of fan body 61 and fan housing body 62, the fan body 61 in enclosed cooling fan 6 are threadedly coupled
On mandrel 2, fan housing body 62 is threaded on the inner wall of magnetic axis bearing 1, and fan body 61 is stretched in fan housing body 62, and fan body
Formed with cooling air channel 60 between 61 and fan housing body 62.Coolant flow channel 21, the coolant flow channel are equipped with the axis direction of mandrel 2
21 and cooling air channel 60 connect.
The side wall of fan body 61 in the present invention is equipped with blade part 613, and fan body 61 and blade part 613 are integrally formed.
The outer circle wall of 61 liang of ends of fan body stretches out and forms boss portion 614, and the inner wall of the boss portion 614 is
Ramp structure.Two boss portions 614 form water conservancy diversion cover structure, and ramp structure is easy to the flowing of wind, good heat dissipation effect.
Fan housing body 62 is made of electric bakelite, and insulating heat-conductive effect is good.Fan body 61, which is adopted, to be formed from aluminium, and intensity is high.
For ease of connecting between coolant flow channel 21 and cooling air channel 60, it is logical that first is equipped with the side wall of fan body 61
Hole 611, is equipped with the second through hole 22 on the side wall of mandrel 2, and 611 and second through hole 22 of first through hole connects, first through hole 611
Connect with cooling air channel 60, the second through hole 22 and coolant flow channel 21 connect.
Ventilation hole 12 is equipped with the axial direction of magnetic axis bearing 1.
Cooling fan of the present invention in rotor lower end uses closed type structure, solves open type cooling fan or external cooling wind
The problem of windage loss consumption of fan is larger, cooling wind enters magnetic axis bearing 1 from ventilation hole 12, enters mandrel 2, increase from coolant flow channel 21
The incoming air area of cooling, by the blade part 613 of enclosed cooling fan 6, will cooling wind along the direction of cooling air channel 60 to
On cool down successively；Cooling air channel 60 reduces cooling windage loss consumption, increases cooling effect.
The above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, some improvement can also be made without departing from the principle of the present invention, these improvement also should be regarded as the present invention's
