Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Switching processes in the DC machine with semiconductor switch on stator and magnetic asimmetry of rotor D.K. KOKHREIDZE Are stated the complex equation of switching processes of valveside machine with a closed asymmetry of stator. The equations are written down in their own coordinates without taking into account the active resistances of stator and rotor phases. The lack of EMF of rotation in equation simplifies the analysis of switching processes. With complex current by feedback transformation are determined the instantaneous values of the current loop of machine in the switching time interval. With taking into account the boundary conditions will be determined the angle of switching machines. Keywords: semiconductor switch, dc machines, complex current, inverse transformation of variables, commutating angle. Contacts: E-mail: stativko1@mail.ru Pp. 24-27.
