Cordless power transfer
Abstract:
A system for cordless transfer of power for appliances or electronic devices 30 has a power transferring device 80 with a plurality of magnets 52 driven by a motor 70B powered by commercial electric power devices or lines. The power transferring device 80 is positioned below a table or countertop 20. On the undersurface of each appliance or electronic device 30 are one or more circular rotating magnetic arrangements 52 with opposing (attraction) poles to drive a dynamo 40 or dynamos. When the motor 70B is switched on, the drive axle 72 rotates a support base 82 upon which a plurality of magnets 52 is attached about an axis which correspondingly moves the plurality of magnets 52 in a circular motion creating a rotating magnetic field 50 to turn the dynamo 40 inside the base of the cordless appliance or electronic device 30.
