Abstract
A control system for a DC electric traction motor which eliminates cogging of the motor during transition from a driving to a plugging mode. The system incorporates apparatus for comparing motor armature current to a plugging current reference voltage which voltage is initially applied as a ramp function to thereby provide a smooth transition into braking.
