Testing of Electric Drive with a Serial Connection of the Same Phases of Two Induction Motors through Computer Simulation
Author:
Abstract: Objective - check the functionality of the circuit of an electric locomotive fan drive that is not speed-controlled, containing two induction motors, the same stator phases of which are connected in series. Methods: computer simulation of electric drive at rated voltage and under-voltage at different values of shaft load and not equal parameters of motors. The simulation results are presented. Results: the simulation showed that, despite the possibility of sustainable operation at rated voltage, this scheme at under-voltage supply is unstable. Conclusion: the auxiliary electric drive circuit with a series connection of the phases of two induction motors is not recommended for use.
