Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Electromagnetic processes in three-phase asynchronous motor with a semiconductor switch on the rotor with a series excitation D.K. KOKHREIDZE Are stated the general equations for the average values of the variables of multiphase AC machines with controlled semiconductor switch (CSS) on the stator and rotor. In the equations are taken into account the magnetic asymmetry of the stator and rotor. From the common equations are obtained equations of various schemes of three-phase asynchronous motors. Separately is considered analysis of the processes in the three-phase asynchronous motor with the CSS on the rotor with the series excitation. By obtained expressions is possible to construct the machine characteristics for different values of the control angle. Keywords: controlled switch; three-phase motor; static mode; dynamic mode; moment; mechanical characteristi Contacts: E-mail: dKokhreidze@mail.ru Pp. 46-49.
