A mathematical model of transient processes of DC motor with three-phase rotor excitation
D.K. KOKHREIDZE

Are derived complex equations of transient processes on the instantaneous values of variables of DC motors with a symmetric excitation
of rotor. The variants of the power winding excitation dc voltage and three-phase AC voltage are considered. The stator winding is
switched by semiconductor switch bridge, assembled on a fully controlled switches. The switches are controlled by signals of the sensor on
a specified control law. From these obtained complex equations are composed scalar equations of transient processes in the convenient for
further solution of computer form. At a constant rotational speed of the rotor is given an analytic solution of transient processes equations
by operator method.
Keywords: switch, semiconductor switch, symmetric excitation, DC motor, electromagnetic torque, control law.
