WebbMany generators are operated at speeds of 1000 rpm or below. That’s quite a low speed for small motors. Generating 10 V or more at 1000 rpm requires a speed constant of only 100 rpm/V or less. Such windings are hard to find in the maxon portfolio. There are only a few high resistance windings on larger motors that satisfy this requirement. WebbTo change the output frequency to 50 Hz for the same generator configuration, the engine speed needs to be reduced to 3,000 rpm. Similarly, for a 4-pole generator, an engine speed of 1,800 rpm produces output of 60 Hz. Reducing the engine speed to 1,500 rpm yields an output of 50 Hz. In the case of small or residential generators, you can alter ...
