Guaranteed and Reliable Excitation of Asynchronous Generator Coupled to Shaft of Vehicle

A method for determining the minimum allowable speed of the asynchronous generator shaft is proposed and the results of graphical and analytical solution for an asynchronous machine are given. The analytical dependence of the minimum allowable speed of the induction shaft as a function of the parameters of the drive motor of internal combustion, capacitive excitation and load, which must be provided by selecting the gear ratio of the mechanical coupling device. The general criterion for selecting the size of the transmission rollers is presented in the form of a quality functional, which takes into account the range of variation of the crankshaft speed of the primary engine, the range of variation of the diameter of the transmission roller and the range of fuel consumption at the corresponding crankshaft speed.
