Abstract
The utility model relates to a forced air cooling magnetor. The utility model is characterized in that the outer surface of a rotor shaft of an ordinary magnetor is fixed with two or more than two air inducing paths in horn shapes; the directions of the air inducing paths are consistent with the rotary direction of a rotor; air inlets are big, and air outlets are small and are over against a stator winding. When the magnetor works, the air inducing paths rotate following the rotor and air enters the air inducing paths from the air inlets and blows the stator winding from the air outlets for cooling the stator winding. The air inducing paths of the utility model have simple structure and easy manufacture and do not need energy resources which are additionally added. The utility model can effectively reduce the temperature of the stator winding for extending the service life of the stator winding.
Description
Technical field:
The utility model relates to a kind of magneto, and particularly a kind of kinetic energy guiding air that utilizes the rotor rotation to produce produces the magneto that convection current reduces the stator coil temperature.
Background technology:
At present, the magneto that automobile, motorcycle are used mainly is made up of stator support, stator coil and the rotor that covers on stator coil outside, and during this magneto work, stator coil is understood because of the generation high temperature that works long hours, not only influence service behaviour, and very easily burnt.How taking a kind of easy method to reduce the stator coil temperature is an open question so far.
Summary of the invention:
The purpose of this utility model provides the air blast cooling magneto that a kind of kinetic energy that utilizes the magneto rotor rotation to produce reduces the stator coil temperature.
The purpose of this utility model is achieved in that a kind of air blast cooling magneto, comprise the stator of forming by stator support and stator coil, and the rotor that covers on the stator coil outside, it improves main points: fix two or more flaring wind channels at the rotor axial outer surface, this wind channel is consistent with the direction of rotation of rotor, its air inlet is the heavy caliber end, and air outlet is facing to stator coil.
The utility model is provided with wind channel by the rotor axial outer surface at magneto, the kinetic energy that produces when utilizing magneto work, the guiding air forms air-flow, and this air-flow rushes at stator coil through wind channel, make it reduce temperature, thereby prolong the useful life of stator coil effectively.
The advantage of this utility model is: simple in structure, handling ease, do not need to increase in addition the energy, and obvious to the cooling-down effect of stator coil.
Below in conjunction with accompanying drawing the utility model is further described.
Description of drawings:
Fig. 1 is a front view of the present utility model.
Fig. 2 is the A-A cutaway view of Fig. 1.
Fig. 3 is the B-B cutaway view of Fig. 1.
The meaning of each numbering is in the above-mentioned accompanying drawing: 1 stator support, 2 stator coils, 3 rotors, 4 wind channels, 5 air inlets, 6 air outlets
Embodiment:
Please see Figure 1, Fig. 2, Fig. 3, the described air blast cooling magneto of this embodiment is made up of stator support 1, stator coil 2, rotor 3, wind channel 4.The stator that constitutes by stator support 1 and stator coil 2 wherein, rotor 3 covers on stator coil 2 outsides, and as shown in Figure 1: two wind channels 4 that are fixed on the rotor 3 are mutually 180 degree angles.Fix two or more wind channels 4 in rotor 3 axial external surface.This wind channel flare, it is consistent with the direction of rotation of rotor 3, and its air inlet 5 is the heavy caliber end, and air outlet 5 is facing to stator coil 2.
The utility model is work like this: when magneto was worked, wind channel 4 was with rotor 3 rotations, and air enters from air inlet 5, through wind channel 4, blows to stator coil 2 from air outlet 6, thereby reaches the purpose that reduces the stator coil temperature.
