Abstract :
This paper describes the theory and characteristics of a drive which provides a wide range of adjustable speeds. The ratio of the maximum to minimum useful speeds attainable is approximately 20-to-1. The system provides high starting-torque, relatively high efficiencies and rapid deceleration through regenerative braking. The drive uses d-c series motors and generators and it can be assembled from standard equipment.
