A DC controlled-velocity drive. An SCR power bridge is energized by a three-phase AC power source for supplying DC voltage to the armature of a DC drive motor when the SCR''s are triggered, shifting of the phase of triggering causing variation of the DC voltage for varying the motor speed. Various regenerative and degenerative feedback circuits are employed, among them being a feedback circuit sensing this DC voltage and a feedback circuit sensing the motor armature current. These feedback circuits produce feedback signals which are compared with motor speed and armature current reference signals for the purpose of controlling the phase of triggering of the SCR''s in order to maintain the motor speed substantially equal to a preselected motor speed while preventing the motor armature current from exceeding a predetermined maximum.
