POWER SUPPLY TRANSFORMER TO ROTOR

摘要

PROBLEM TO BE SOLVED: To supply power to a circuit which is installed on a rotor on a noncontact manner. SOLUTION: In a transformer, an iron core of an inner iron type is used, and a secondary winding 5 is annularly wound as passed through an iron core frame 4. A primary winding 2 is wound around the iron core 4, and the iron core is provided with a gap 7 through which a plate 8 for supporting the secondary winding 5 from the rotor and lead wires 6 of the secondary winding are passed. The iron core 4 and primary winding 2 are positioned in a stationary side, so that the secondary winding 5 is rotated integrally with the rotor to supply power to a circuit of the rotor through electromagnetic coupling.
