An electromagnetic levitation force type propulsion device includes an integrated electromagnet structure, an auxiliary propulsion structure and a power supply control structure. The integrated electromagnet structure includes a mounting frame, a propulsion outputting shaft capable of moving back and forth relative to the mounting frame and extending out of the mounting frame, and two electromagnets opposite to each other. One of the electromagnets is assembled to the mounting frame to form a stationary electromagnet and the other electromagnet is fastened to the propulsion outputting shaft to form a movable electromagnet. The movable electromagnet is provided at the other side of the mounting frame and can move back and forth relative to the stationary electromagnet. The auxiliary propulsion structure drives the movable electromagnet back and forth relative to the stationary electromagnet. The power supply control structure provides a power supply for the integrated electromagnet structure and/or the auxiliary propulsion structure.

A system and method for detecting integrity of a position for a mover in an independent cart system, includes receiving multiple first position feedback signals at a first processing core and receiving multiple second position feedback signals at a second processing core. Each of the first and second position feedback signals are generated by first and second position sensors, respectively, by detecting a magnet array mounted on the mover. A first value of the position of the mover is generated with the first processing core responsive to the first position feedback signals, and a second value of the position of the mover is generated with the second processing core responsive to the second position feedback signals. The first and second values of the position of the mover are compared with either the first or second processing core to verify operation of the first and second position sensors.

The invention provides in some aspects a transport system comprising a guideway having a plurality of regions in which one or more vehicles are propelled, where each such vehicle includes a magnet. Disposed along each region are a plurality of propulsion coils, each comprising one or more turns that are disposed about a common axis, such that the respective common axes of the plurality of coils in that region are (i) substantially aligned with one another, and (ii) orthogonal to a direction in which the vehicles are to be propelled in that region. The plurality of coils of at least one such region are disposed on opposing sides of the magnets of vehicles being propelled along that region so as to exert a propulsive force of substance on those magnets. In at least one other region, the plurality of coils disposed on only a single side of the magnets of vehicles being propelled in that region exert a propulsive force of substance thereonregardless of whether the plurality of coils in that region are disposed on a single or multiple (e.g., opposing sides) of those magnets.
