Abstract
The invention discloses a rotor return air cooling structure of a magnetic suspension motor with an isolated rotor. The rotor return air cooling structure comprises a base, a magnetic suspension bearing, the rotor, a stator, a sheath, a cooling fan, a sheath exhaust tube, a cooler and a sheath return pipe, wherein one end of the sheath is open and the other end is closed; the magnetic suspension bearing and the stator are supported on the base; the sheath is arranged in the magnetic suspension bearing and the stator in a penetrating manner; the rotor is arranged in the sheath in a penetrating manner; the cooling fan is fixed on the rotor; one end of the sheath exhaust pipe communicates with the sheath and the other end communicates with the cooler; and one end of the sheath return pipe communicates with the cooler and the other end communicates with the sheath. According to the rotor return air cooling structure, a gas in the sheath can circularly flow between the sheath and the external cooler; heat is absorbed from the surface of the rotor by using gas flow for cooling the rotor, and then exhausted through the external cooler, so that the rotor can be effectively cooled through a gas flow circle and a heat cycle.
Description
Technical field:
The present invention relates to a kind of rotor backflow air-cooled structure of isolation rotor magnetic suspension motor.
Background technology:
Isolation rotor structure magnetic suspension motor have good sealing it is adaptable to various requirement fine vacuum, zero leakage or
The occasion of toxic and harmful.But because rotor is wrapped up by sheath in isolation rotor structure, do not have in sheath or only have
A small amount of gas flowing, and only lean on radiation heat transfer efficiency to be far below heat convection, the heat that therefore rotor produces is difficult to discharge,
Easily cause rotor and cross cause thermal damage.
Therefore, it is necessory to improve prior art to solve the deficiency of prior art.
Content of the invention:
The present invention is to provide a kind of isolation rotor magnetic suspension motor to solve the problems, such as above-mentioned prior art
Rotor backflow air-cooled structure.
The technical solution adopted in the present invention has: a kind of rotor backflow air-cooled structure of isolation rotor magnetic suspension motor, bag
Include pedestal, magnetic suspension bearing, rotor, stator and one end open, the airtight sheath of the other end, described magnetic suspension bearing and stator
It is supported on pedestal, sheath is arranged in magnetic suspension bearing and stator, rotor is arranged in sheath, also include cooling fan, shield
Set exhaustor, cooler and sheath return duct, described cooling fan is fixed on rotor, one end of sheath exhaustor and sheath
It is connected, the other end is connected with cooler, one end of sheath return duct is connected with cooler, and the other end is connected with sheath
Logical.
Further, described cooler is air-cooled cooler or water-cooling cooler.
The invention has the following beneficial effects: the present invention can make the gas in sheath between sheath and external cooler
Generation circulates, and absorbs heat, cooling rotor using gas flowing from rotor surface, then passes through external cooler by heat
Discharge, by such gas flow circuit and thermal cycle, effectively can cool down rotor, thus solving to isolate rotor magnetic suspension
A rotor cooling difficult problem for motor.
Brief description:
Fig. 1 is present configuration figure.
Specific embodiment:
The present invention is further illustrated below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of rotor backflow air-cooled structure of present invention isolation rotor magnetic suspension motor, including pedestal 1, magnetic
Suspension bearing 2, rotor 3, stator 4 and one end open, the airtight sheath of the other end 5, magnetic suspension bearing 2 and stator 4 are supported on
In pedestal 1, sheath 5 is arranged in magnetic suspension bearing 2 and stator 4, and rotor 3 is arranged in sheath 5.
For ease of the rotor 3 of cooling isolation rotor magnetic suspension motor, it is provided with cooling fan 61, sheath exhaustor 62, cooling
Device 63 and sheath return duct 64, cooling fan 61 is fixed on rotor 3, and one end of sheath exhaustor 62 is connected with sheath 5,
The other end is connected with cooler 63, and one end of sheath return duct 64 is connected with cooler 63, and the other end is connected with sheath 5
Logical.
Cooler 63 in the present invention is air-cooled cooler or water-cooling cooler.
Cooling fan 61 is coaxially mounted on rotor, produces pressure differential for driving the gas in sheath 5 to flow, sheath is arranged
Gas after cooling fan 61 is pressurizeed is drawn in sheath 5 by trachea 62, and imports external cooler 63.Cooler 63 leads to
Cross air-cooled or water-cooled mode and the hot gas that sheath exhaustor 62 imports is cooled to lower temperature, will be cold through external cooler
But the gas after is directed in sheath 5 again through sheath return duct 64.
Said structure operates jointly, and the gas in sheath can be made to produce recycle stream between sheath and external cooler
Dynamic, absorb heat, cooling rotor using gas flowing from rotor surface, then by external cooler, heat is discharged, pass through
Such gas flow circuit and thermal cycle, can cool down rotor effectively, thus solving to isolate turning of rotor magnetic suspension motor
A son cooling difficult problem.
The above is only the preferred embodiment of the present invention it is noted that ordinary skill people for the art
For member, some improvement can also be made under the premise without departing from the principles of the invention, these improvement also should be regarded as the present invention's
Protection domain.
