Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Control of non-stationary modes valveside electrical machine with a closed anchor winding D.K. KOKHREIDZE The equations of non-stationary modes of DC valveside electrical machine are obtained. Due the application of complex transformation of variables are obtained the scalar equation for the commutation and inter- commutation intervals of time. At a constant rotor rotation speed the equations of transients processes are solved by an operator method. Are generated and solved the equations of commutation processes by neglecting the active resistance of stator and rotor. Keywords: controlled commutator, valveside machine, rotor’s position sensor, switching, kinematic inductance, thyristor, longitudinal synchronous resistance, transversal synchronous resistance.
