Abstract (en)
A transformer for coupling electrical power from a stationary location to a moving location with a minimum of disturbance forces between the stationary and movable components. The transformer is particularly adapted to coupling power to a magnetically suspended platform. The transformer includes an enclosed core housing (112) two windings, a stationary primary coil (116), and a secondary coil (117) free to move linearly and angularly over a limited displacement, where the secondary coil is affixed to the movable platform (110), thereby enabling energy to be extracted for powering apparatus mounted within the platform.
