Abstract: PURPOSE:To detect DC currents at the rotor side by means of noncontact by a mechanism wherein a rotor magnetic path interlinking with one portion of a current commutating curcuit provided on a rotor shaft is made up to the one portion of the current commutating circuit, and a core magnetic circuit connecting to themagnetic path once at every turn is provided at the stator side. CONSTITUTION:A connecting wire 3 for introducing DC currents converted by means of a rotary rectifier to the field winding 2 of a main machine is fitted onto a shaft 1. The connecting wire 3 consists of two wires, and one is used as a connecting wire 3a for flowing currents to the field winding and the other as a feedback conecting wire 3b from the field winding. A noncontact current detector 4 is mounted to a portion where the connecting wire 3 creeps on the shaft. A core 5 at the rotor side which surrounds the connecting wire and uses the shaft 1 as one portion of a magnetic circuit is installed at the rotor side. A coil 8 for detection is wound on a core 7 at the stator side, which opposes the core 5 at the rotor side interposing voids 6 and forms the magnetic circuit, at the stator side. Thus, magnetic flux interlinking with the detecting coil 8 changes during revolution, and voltage proportional to currents flowing through the connecting wires 3a, 3b is induced to a coil terminal.
