Description
Technical field
The utility model relates to a kind of magneto alternator rotor ventilation frid, belongs to magneto alternator aeration technology field.
Background technology
At present, it is bad that the known permanent magnet generator being applied to generator also exists permanent magnet heat radiation all to some extent, the defects such as permanent magnet easily demagnetizes, what the most extensively adopt in motor manufacturing is take air as the air cooling system of coolant, according to the direction of flow of cooling air in motor, air cooling system can be divided into radial direction, axial and hybrid three kinds, due to the blasting action adopting the air cooling system of radial ventilation to be convenient to utilize the parts that rotor can produce blast, thus be widely used, but, in prior art, the rotor of radial ventilation is adopted only to be directed to as round rotor punching, the vent segment of rotor welds with ventilating board direct spot welding, vent segment is caused to fly out for preventing vent segment solder joint from coming off, welding quality requires higher, and add inspection cost.
Summary of the invention
Technical problem to be solved in the utility model is the defect overcoming prior art, provides a kind of magneto alternator rotor ventilation frid, and it can improve the performance of ventilating of the p-m rotor adopting modular magnetic pole.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: a kind of magneto alternator rotor ventilation frid, and for being arranged between adjacent modular magnetic pole, it comprises body, and body has:
Base plate, the both sides of base plate are respectively arranged with the link slot be connected with modular magnetic pole for it;
Multiple dividing plate, it is connected on base plate, and is arranged in the radial direction of rotor, forms inlet side between the bottom of dividing plate, forms air side between the top of dividing plate.
The further technical problem to be solved of the utility model is: the leakage field phenomenon reducing permanent magnet, described base plate and/or dividing plate are made up of non-magnet material.
Further in order to increase its radial ventilation effect better, when body is arranged on rotor, the inlet side formed between the bottom of described dividing plate is towards modular magnetic pole, and the air side formed between described dividing plate top is towards the stator side of magneto alternator.
Further in order to improve its reliability, when preventing rotor high-speed from rotating, cause dividing plate to fly out due to not prison welding thus cause the phenomenon of generator failure, the corresponding site that described base plate connects at dividing plate is provided with groove, the position that described dividing plate is corresponding is provided with double wedge, and base plate is connected on base plate by the connection of groove and double wedge.
Conveniently this ventilation channel plate and modular magnetic pole are fixed further, and the edge described base plate being formed link slot is provided with multiple semicircle welding hole.
Further, described base plate and/or the thickness of dividing plate are 1mm ~ 2mm.
Further, described dividing plate is 6mm ~ 8mm along the width in the vertical direction of base plate.
After have employed technique scheme, the utility model has following beneficial effect:
1, the utility model adopts radial ventilation cooling, and make rotor permanent magnet near the air intake position of cooling air, air-out position, in stator side, makes the temperature of rotor permanent magnet avoid the position that in wind path, temperature is the highest, improves the runnability of generator;
2, reasonably have selected the material of ventilation channel plate, reduce the leakage field of permanent magnet;
3, the reasonable design shape of dividing plate, adds the effect of generator radial ventilation better;
4, dividing plate designs double wedge, machined grooves on base plate, the double wedge of dividing plate is corresponding with bottom plate groove assemble after, again the position of groove is welded, add reliability, prevent rotor high-speed from rotating, because not prison welding causes dividing plate to fly out, make the phenomenon of alternator failure.
