ASYNCHRONOUS GENERATOR

There is claimed an asynchronous generator (fig.1) comprising rotor (1) and stator (2) on which multiple of 2m1m2 teeth (3-20) and a definite number of coils (21) are arranged, the coils belonging to the primary (22) and secondary (23) windings with phase number m1 and m2, correspondingly. The asynchronous generator offered is characterized in that coils of secondary winding, similarly as the coils of primary winding, are arranged on stator (2). Rotor (1) is windingless. In order to provide necessary electromagnetic connections between the windings, each stator's tooth is wrapped with four coils belonging to different phases of the windings. One half of teeth (3-20) are wrapped with the coils of the secondary winding of one wrapping direction while the other half is wrapped with those of the opposite wrapping direction. The required electromagnetic connections are also provided by the properly chosen number of teeth (24) of rotor (1). To raise the specific power, secondary winding (23) is terminated in capacitors (27), the capacity of which is resonant for the secondary circuit at the frequency of critical slip. In order to simplify the technology of dropping the windings, it is possible the latter to be arranged on the internal stator, with the external rotor embracing the stator. The advantages of the claimed generator are the improved reliability and large number of poles, which makes it possible to use this generator in low-turn wind plants without a multiplier, brushes and rings.
