Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Integrated equation transition modes of threephase induction motors feeding from singlephase main D.K. KOKHREIDZE Are derived the complex equations of transient modes for the most common schemes of three-phase induction motors including in single-phase main. The complex transformation of variables greatly simplifies the analysis of electromechanical processes in these systems. The equations of transients processes may be presented in the coordinates of d and q form prepared for solutions on computer. At a constant motor speed the equations are solved analytically. Keywords: three-phase induction motor, complex transformation of variables, phase-shifting element, coordinate system of the stator, torque. Contacts: E-mail: dkokhreidze@mail.ru Pp. 19-23.
