Research of non-stationary electromagnetic processes in synchronous electric drive

Mathematical model of transient electromagnetic processes in synchronous electric drive that allows investigating the influence of non-sinusoidal and differential currents and voltages at electromechanical processes are proposed. A mathematical dependence that characterizes the vibration of the rotor under mechanical loading relatively to the synchronous mode is obtained. Simulation of asymmetry power supply of synchronous electrical drive is performed. Electromagnetic and electromechanical processes in a synchronous electric drive are shown. Sharply variable electric loads are exciting and lead to an increase in shaft oscillations that exceed the normative technical documentation has shown.
