Japanese Patent JPS5193319
Kind Code:
A
Abstract:
A field-controlled direct current motor is provided with a circuit responsive to armature current which is adjustable as to the amount of armature current representative signal, and the adjusted current representative signal is used to provide a selected amount of droop in the speed-load characteristic of the motor. A plurality of individually field-controlled direct current motors operating in parallel on a common load are individually adjusted as to the amount of sensed armature current to provide through field control individual selected amounts of droop in the respective speed-load characteristics.
