摘要： An electromagnetic system for a magnetic levitation vehicle comprises a "W" shaped magnet core having a center pole wound by a superconducting coil and side poles on opposite sides of the center pole, each wound by an ambient temperature coil. Quasi-dc power is supplied to the central superconducting coil for levitation of the vehicle with respect to a rail along which the vehicle is meant to move. The ambient temperature coils are connected in series to each and other and powered with ac power for trimming and controlling the gap between the magnet and the rail.

摘要： A system and method for connecting superconducting magnet coils made up of coil segments to allow an integrated winding concept. The integrated winding concept can include serially connecting coil segments of coil pairs in an alternating pattern, which causes coil pairs to be electrically symmetric. Symmetric coil pairs can eliminate or significantly reduce the currents in magnet coils induced by gradient or other pulses, produce a homogenous field, and reduce the accumulated voltages in the coils due to gradient pulsing.
