Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Transitional processes for the a DC valve motor with a symmetrical excitation on the rotor D.K. KOKHREIDZE The analysis of transient processes in a valve motor with a three-phase excitation winding fed by a DC voltage source is carried out. On the stator of motor is arranged semiconductor bridge switch controlled by the rotor position sensor. The calculation of the processes is carried out on the instantaneous values of the quantities in combination with the complex transformation of variables. With a general asymmetry of the stator and rotor windings, we obtain differential equations with constant coefficients. Keywords: valve motor, rotor position sensor, switch, operator image.
