Bezprzekładniowa prądnica małej mocy do zasilania urządzeń pomiarowych

The paper presents the construction and basic characteristics of gearless generator using to supplying devices serving to the measurement, recording and transmission of the wind speed. Required low cogging torque of generator has been obtained at straight teeth of stator and straight magnets of rotor, by the number of rotor poles different from the number of teeth of stator. Thanks to it, the generator starts at low wind. Low power of generator and soft output characteristic allow for charging the battery sustaining the supplement without additional electronic devices. The images of the rotor and stator of the generator illustrate the construction of generator.
