Choice of Electric Engines Connection Circuits in Electric Machine Unit of Electric Power Generation Device

The purpose of this research is to study and select the type of engine and circuits for connecting their windings in the generator operating mode of the electric machine unit for the device of converting kinetic and mechanical energy of rotation in the electric one. The design and principle of the device, which transforms the kinetic energy from pressure into electric one, is proposed. The results of experimental studies on the determination of the most efficient type of electric engine in accordance with the value of the generated power output are presented. According to the results of experiments, it was determined that a stepper motor DSh 200-1 is more efficient for one rotation in the forward and reverse direction with frequency f = 1.185 Hz. The processing of experimental research was carried out using integral methods of mathematical physics, namely the trapezoid method. Integration of the received oscillograms allowed to determine the most effective circuit of connection of stepper motor DSh-200-1 stator windings. For one rotation in the forward and reverse direction with frequency f = 1.185 Hz, the given circuit will provide the power of 0.164 Watt.
