Influence of frequency on the synchronous electrical machine parameters

The current and moment of resistance to rotation of the inductive synchronous electric machine under inductive load have been considered. For a synchronous machine with an inductive load, Theorem 1 is valid: the current amplitude in the inductive load of an inductive synchronous electric machine is independent of the rotational speed. The theorem has been proved by equating the second Kirchhoff law and the law of electromagnetic induction with reference to a rotating machine. Theorem 2 is also valid: the moment of resistance to rotation for an inductive synchronous electric machine with an inductive load is independent of the rotational speed. The theorem has been proved by analyzing the Ampere law with respect to a rotating machine. It has been established, with active load, the current amplitude and the moment of resistance to rotation depend linearly on the rotational speed. However, with capacitive load, these parameters are quadratically dependent on the rotational speed...
