Abstract
The specification discloses an exercise treadmill for diagnostic and therapeutic purposes incorporating an improved drive and control system. High efficiency at low rpm is effectuated through the use of a DC motor which maintains the belt speed constant by varying the width of the applied pulse duration as a function of load. Additional load buffering between the belt and motor is effectuated by a double flywheel configuration.
