PCT No. PCT/EP94/00789 Sec. 371 Date Sep. 14, 1995 Sec. 102(e) Date Sep. 14, 1995 PCT Filed Mar. 14, 1994 PCT Pub. No. WO94/21995 PCT Pub. Date Sep. 2, 1994An apparatus for balancing a rotating body, in particular the grinding wheel of a grinding machine, comprises an assembly secured to the grinding wheel and rotating with it, with masses having an adjustable arrangement, electrical motors for controlling adjusting movements of the masses, and electrical circuits with a microprocessor unit. A transceiver terminal between a control unit and the rotating assembly provides a first contactless transmission channel for inductively coupling a fixed power source to the rotating parts, and a second contactless transmission channel for transmitting information in both directions. The second transmission channel may comprise optoelectronic devices. |
