CONTROL MEANS FOR DDC MOTOR

PURPOSE:To smooth speed characteristics of and alleviate burden in the design of a d - c motor, in which an armature current is caused to flow only in one direction while causing field current in opposite directions, by a control means adapted to vary the armature current when a torque command excee...

Zusammenfassung:	PURPOSE:To smooth speed characteristics of and alleviate burden in the design of a d - c motor, in which an armature current is caused to flow only in one direction while causing field current in opposite directions, by a control means adapted to vary the armature current when a torque command exceeds the positive or negative limit value of the fueld current.
