Abstract
A DC motor drive system for providing an enhanced motor speed/torque relationship, where circuits modify the motor field winding control switching sequence to compensate for speed effects on motor torque output and to compensate on transient loading effects on motor torque output, and to compensate for rotor inertial effects caused by transient motor load changes.
