A three phase power source is used with the linear synchronous motor to produce a traveling magnetic wave which in conjunction with the magnets propel the vehicle. The conductive guideway combines with the superconducting magnets to provide for vehicle leviation.Field of SearchGrip or plow trapsSLOTTED CONDUIT Yokes TRUCK IN CONDUIT MAGNETICALLY SUSPENDED CAR Propulsion means employed to suspend car By permanent magnets only Including means to sense or control car position or attitude with respect to guideway Construction or composition of suspension elements Linear motor Propulsion by active guideway; e.g., linear synchronous motor, etc. Including means to control gap Construction or composition of motor elements | |
