Abstract: A method of constructing a roadway having an embedded linear synchronous motor (LSM) utilizes prefabricated modules. Structurally, each module comprises a top plate, a multiple-phase winding tied to the top plate, and a concrete mold encapsulating the winding. With the modules prefabricated, the roadway is constructed by first excavating a trench to position a foundation at the trench bottom. Then a mud matt is positioned on the foundation. Next, the modules are laid end-to-end on the mud matt. Thereafter, the windings in adjacent modules are electrically interconnected through joints. Further, the joints are covered by junction boxes, and the trench around the roadway is filled in with aggregate.

Abstract: An all-electric, wheeled vehicle has a magnet array that can be selectively moved between a retracted position and a deployed position, to respectively operate in a motor mode or a generator mode. When in the motor mode, with its magnet array retracted, wheel rotation to move the vehicle is powered by an onboard battery. Alternately, in the generator mode with the magnet array deployed, the vehicle is powered by a Linear Synchronous Motor (LSM). Specifically, the deployed magnet array interacts with a multiple-phase winding (i.e. LSM) embedded into the roadway on which the vehicle travels. Further, rotation of the wheel during vehicle movement in the generator mode recharges the battery.

Abstract: A system and method are provided for moving a vehicle along a roadway. The system includes at least one power segment that incorporates a multiple-phase winding. Structurally, the winding is embedded into the roadway for interaction with a magnet system mounted on the vehicle. With this interaction, a Linear Synchronous Motor (LSM) is established between the roadway and the vehicle to drive movement of the vehicle along the roadway. Also, the vehicle includes a mechanism for initially synchronizing a waveform speed of the multiple-phase winding with the speed of the vehicle. Further, the vehicle is able to selectively establish the LSM for use when desired.

Abstract: A MAGLEV guideway module which can be supported by vertical columns to create a section of an elevated MAGLEV guideway is disclosed. The module includes a deck and an elongated box beam that are form cast together in a unitary monolithic construction and made of lightweight, steel reinforced concrete. Functionally, a plurality of modules cooperate to form an elevated levitation track that supports the operational electromagnetic guideway components and is designed to support the weight of a MAGLEV vehicle. For the module, the beam can be an elongated, hollow beam, such as a box beam, which is made of a molded, pre-stressed concrete. A molded-concrete transverse deck is integrally formed on the hollow beam. The deck includes first and second cantilevers that each extend from the beam in opposite directions. Together, the cantilevers and beam establish a substantially flat deck surface over which a MAGLEV vehicle can travel.

Abstract: A system for levitating and propelling a vehicle along a stationary guideway includes a linear synchronous motor (LSM) having a component mounted on the vehicle and a component mounted on the guideway. The LSM components interact to generate electromagnetic forces that act to levitate the vehicle and electromagnetic forces that act to propel the vehicle along the guideway. The gap between LSM components is maintained by an electrodynamic system (EDS) having a component mounted on the vehicle and a component mounted on the guideway. The EDS components cooperate to create an electromagnetic force that acts with the levitation forces created by the LSM to maintain the LSM gap within a predetermined range. Maintenance of the LSM gap stabilizes the LSM and allows the LSM to operate efficiently within a pre-selected range of vehicle speeds.
