Abstract
The utility model relates to a cooling system for magnetic generators, which is suitable for magnetic generators, in particular to the cooling of magnetic generators, and mainly comprises a motor shell, a stator shell, a stator, a magnet, a rotor, a bearing, a stator cooling plate and a main air inlet. Compared with the existing technology, the utility model efficiently brings heat generated during operation of power generators and works well under dusty, damp, flammable and explosive environment.
Description
Technical field:
The utility model relates to a kind of permanent magnet generator cooling system, is applicable to permanent magnet generator, and particularly permanent magnet generator cools.
Background technology:
Permanent magnet generator uses the rotor as generator that rare earth permanent magnet is housed usually, and this is high speed rotating in the stator of generator, and its rotating speed is that per minute 150 forwards per minute 20000 commentaries on classics to, and the stator of permanent magnet generator then comprises the stator winding coil.Because the huge energy of rare-earth magnet and high-speed cruising (requiring to use the rare-earth magnet of bulk during its low cruise), this generator can produce very large power output, simultaneously, the stator of generator and rotor all can produce a large amount of heat energy, if can not from generator, get rid of these heat energy effectively, can damage the winding coil of generator and make epitrochanterian magnet demagnetization.In some application, for example, when providing the generator work of electric power, under short circuit and anti-good peak load situation, can cause permanent magnet generator extremely overheated for electric welding machine.For this reason, someone has invented water-cooled generator, purpose is the heat that can get rid of in the generator, but in fact, water-cooled generator can not cooled electric generator rotor portion, and quite complicated and need circulating pump and radiator, water-cooling system is wherein more likely leaked cooling fluid and is lost generator system.
Summary of the invention:
The purpose of this utility model provides a kind of permanent magnet generator cooling system, and it can overcome the deficiencies in the prior art.
The utility model is achieved in that it mainly comprises: motor housing, stator casing, stator, magnet, rotor, bearing, stator fin, primary air inlet, wherein, motor housing wraps in outside the stator casing of the stator fin with arranged radially, rotor is a hollow-core construction, magnet cartridge is on rotor, rotor and magnet are rotatably installed in the stator, and bearings is at the two ends of rotor, and primary air inlet is located at the afterbody end of rotor.
The utility model compared with prior art can be taken away the heat that produces in the generator course of work expeditiously, can be well works in many dirt, humidity and inflammable and explosive environment.
Description of drawings:
Fig. 1 is a structural representation of the present utility model
Embodiment:
As shown in Figure 1, the utility model mainly comprises motor housing (1), stator casing (2), stator (3), magnet (4), rotor (6), bearing (7) and (8), stator fin (15), primary air inlet (16), wherein, motor housing (1) wraps in outside the stator casing (2) of the stator fin (15) with arranged radially, rotor (6) is a hollow-core construction, magnet (4) is contained on the rotor (6), rotor (6) and magnet (4) are rotatably installed in the stator (3), bearing (7) and (8) are supported on the two ends of rotor (6), and primary air inlet (16) is located at the afterbody end of rotor (6).
In this enforcement, primary air inlet (16) is provided with air cleaner (22), is provided with a plurality of blades (27) that are axially-aligned in the rotor (6).
During work, rotor (6) high speed rotating, under the effect of the blade (27) of same high speed rotating, extraneous air is by air cleaner (22), primary air inlet (16) is brought in the rotor (6), absorbed the heat of rotor (6) and magnet (4), form hot-air (17), and be forced to send between motor housing (1) and the stator casing (2) in the formed passage, the heat that produces from stator (3) then passes on the stator fin (15) through stator casing (2), converge formation hot-air (17A) with hot-air (17), be discharged in the atmosphere, thereby get rid of heat in the generator effectively.
Claims (3)
1, a kind of permanent magnet generator cooling system, has motor housing (1), stator casing (2), stator (3), magnet (4), rotor (6), bearing (7) and (8), it is characterized in that having stator fin (15) and primary air inlet (16), wherein, motor housing (1) wraps in outside the stator casing (2) of the stator fin (15) with arranged radially, rotor (6) is a hollow-core construction, magnet (4) is contained on the rotor (6), rotor (6) and magnet (4) are rotatably installed in the stator (3), bearing (7) and (8) are supported on the two ends of rotor (6), and primary air inlet (16) is located at the afterbody end of rotor (6).
2, a kind of permanent magnet generator cooling system according to claim 1 is characterized in that primary air inlet (16) is provided with air cleaner (22).
3, a kind of permanent magnet generator cooling system according to claim 1 and 2 is characterized in that being provided with in the rotor (6) a plurality of blades (27) that are axially-aligned.
