Multihundred-Kilowatt Rotary Electrical-Transfer Device
Roll-ring electrical-power-transfer device capable of transferring high power (hundreds of kilowatts) through rotating connection. Roll-ring assembly transfers up to 500 V at 200 A per circuit, either dc or ac to frequencies of 20 kHz. Assembly has eight power circuits. Outstanding feature of design very low power loss - only 16 W per circuit while transferring 100 kW. Terrestrial application requiring power to transfer through rotating joint with low losses uses roll-ring technology. Used in air or vacuum with no design changes.
