Abstract

The material of this thesis is concerned with analyzing a unique form of control for a separately excited DC motor. Through the use of semiconductor devices, the angular velocity of the motor and driven system are maintained nearly constant under variations of load. The operating mode of the control, zero level switching, provides for two states; either a sequence of rectified sine wave pulses applied to the motor armature, or the motor is derivation for angular velocity changes, during the "on-off" action, is also presented.
