Abstract
An adjustable-speed drive using a d-c series generator supplying a d-c series motor is described. This drive operates well at speeds under 10 rpm as well as at speeds limited only by mechanical considerations. The ratio of maximum to minimum speed, Fig. 4, is in the order of 100 to 1. The drive has the high starting-torque characteristic of the series motor, and it requires no elaborate control equipment. The speed is essentially constant between no load and full load for each setting of a control-field rheostat.
