Abstract

The device for automatic control of direct current motors is characterized in that one armature current control unit (10) is mechanically attached to the motor rotor so as to rotate along with it and receives positive and negative DC supply voltage through two slip rings (18 and 20) cooperating with two brushes (22 and 24) which are in turn connected to the DC power source, while appropriate information transmission media outside the motor provide the control unit (10) with the information required to accomplish armature current control.
