Features (1) Highly effective permanent-magnet generator or the battery charger, the optimized design, the structure is compact. Not brushes, does not need the excitation, does not produce the spark. Does not need to replace brushes, protection rank: IP*4, the water, the putty, the dust cannot enter in the electrical machinery, the service life is long.This generator can widely used for lots of machinery or equipment , the vehicles specially. (2) Non-exciting winding, the generatorrotor intensity is high, the generatormay achieve compares the high speed. (3) Non-excitation control box, the structure is simple, reliable enhancement. (4) Volume small, the weight light, the energy density is big, suits the specific situation. (5) The generatorhighly effective moves in the entire speed range, saves the energy. 6) generatoruses the jack-in rare earth magnet steel, jolts specially suitably, starts repeatedly, is reversing the movement need. (7) generatoruses the forced-air cooling or the water cooling, the temperature is low, the generatoruses the import oiliness high speed bearing, exempts the maintenance, the reliability is high, the generatorlife is long. (8) May according to need to change parameters and so on generatorvoltage, rotational speed, power, may change the generatoroutlook, may use the spline axle elongation, the double axle elongation, the aluminum nature outer covering, front end stops ways and so on mouth output.
