The width of said motor housing is 380mm～480mm.
Said fluid can be a gas, also can be liquid.When magnetic links was equipped with the operation of metallic sheath magneto, having the part of big electric current mainly was magnet exciting coil, and the heat of magnet exciting coil is directly passed to wound core.Wound core is pressed close to epitrochanterian magnetic links again, so the heat on the magnetic links mainly is directly from wound core.The utility model is left the heat radiation through hole on wound core, through the fluid of the heat radiation through hole of flowing through the heat on the wound core is taken away, and has stoped the transmission of heat to magnetic links effectively.Thereby guaranteed that magnetic links is operated in the lower environment of temperature, and then guaranteed the useful life of magnetic links.
Heat radiation through hole two ends on the said wound core are respectively equipped with heat radiation conduit, the outside UNICOM of said heat radiation conduit and motor housing.Said heat radiation conduit can make heat radiation through hole and extraneous UNICOM convenient.
Said power is that the magneto of 110KW to 250KW comprises that also one is arranged on the outer fan blade of motor housing, and said fan blade is installed on the said centre of rotor axle.The opening of said heat radiation conduit is positioned at said fan blade one side.Drive fan blade during rotor rotation and rotate, fan blade is impelled air flow, and then makes the air heat radiation through hole in the said wound core of flowing through, and then takes away heat, reaches to guarantee that magnetic links is in the purpose of the low state of temperature.
The rotating shaft front end and the rotating shaft rear end of said motor housing and said central shaft are rotatably connected respectively, said rotating shaft front end and said rotating shaft rear end one of them with said motor housing between be connected through insulating element.
Said motor main body has the basic function of magneto.In magneto main body rotation process, there is the rotor of high-intensity magnetic field, relative high speed rotating with the stator that has high-intensity magnetic field.Rotation process is understood the axial current that produces stronger axial electric field even have high order harmonic component owing to there is stronger changes of magnetic field on rotor axial under the effect in magnetic field.Axial current can form the closed-loop path through central shaft and motor housing, and system is worked the mischief.Above-mentioned design through between end of said central shaft and said motor housing, insulating element being set, realizes insulation, and then cuts off the circuit closed loop between central shaft and motor housing, eliminates axial current, to improve systematic function as far as possible.
The said rotating shaft rear end of said central shaft is connected to said motor housing through rear end bearing, is provided with insulating barrier between said rear end bearing and said motor housing.To realize insulation.Said insulating barrier can adopt the engineering plastics layer.Because the power that rear bearing bore is less relatively, and insulating barrier is arranged between said rear end bearing and said motor housing, can reduce the stressed of insulating barrier, helps to increase the service life.
Beneficial effect: owing to adopted technique scheme, the utility model has reduced the volume and weight of motor main body, with the noise and the energy consumption of further minimizing the utility model when not changing original motor main body power.And the utility model can also allow to have higher load, and higher work is renderd a service, and guarantees that magneto does not demagnetize, and prolongs the useful life of motor main body.
