ABSTRACT:
A floating carrier type transporting system comprises guide rails whose bottom section is formed by a ferromagnetic material, a carrier free to run along the guide rails, a magnetic supporting device for floating the carrier, a linear induction motor for drining the carrier that is floated by the magnetic supporting device to run along the guide rails, a sensor unit for detecting the changes in magnetic reluctance and/or magnetomotive force in the magnetic circuit that is mounted on the carrier, a control device for controlling the excitation current that is to be flowed in the electromagnet based on the output from the sensor unit, and a roll damping device for damping the rolling that is generated in the carrier in the state of running under the action of the magnetic supporting device and the linear induction motor.
