摘要： A magnet unit includes a first magnetic pole (7a), a second magnetic pole (7b) and a third magnetic pole (7c) at a center between the first magnetic pole (7a) and the second magnetic pole (7b), providing an E-shaped configuration. In the magnet unit, a first magnet is defined between the first magnetic pole (7a) and the third magnetic pole (7c) by connecting two electromagnets (71aa, 73aa) with each other through a permanent magnet (72a), while a second magnet is defined between the second magnetic pole (7b) and the third magnetic pole (7c) by connecting two electromagnets (71ba, 73ba) with each other through a permanent magnet (72b). With this configuration, it is possible to reduce a deviation in the length of respective magnetic paths from the permanent magnets (72a, 72b) up to their respective magnetic poles. By controlling exciting currents to the respective magnetic poles. By controlling exciting currents to the respective electromagnets (71aa, 73aa, 71ba, 73ba), it is also possible to adjust fluxes (or flux density) in respective directions x, y individually.

摘要： An exciting voltage arithmetic portion calculates an exciting voltage of an electromagnet using a signal of a gap sensor. On the other hand, a sensorless exciting voltage arithmetic portion calculates an exciting voltage of the electromagnet using a signal of the current sensor. The exciting voltage adjusting portion adjusts a mixing ratio between an output value of an exciting voltage arithmetic portion and an output value of the sensorless exciting voltage arithmetic portion corresponding to a gap length. The excitation of the electromagnet is controlled according to an output value of the exciting voltage adjusting portion so as to reduce influences of noises on the gap sensors thereby always achieving a stable levitation control.

摘要： In a transporting system for transporting cargo to a predetermined position, a carrier is located above rails and a first support plate is located under the rail and is coupled with the carrier by a pair of columns. A second support plate is rotatably coupled by a coupling mechanism. Four magnetic floating assemblies are so disposed on the first and second plates as to face the rails and a control unit is disposed on the first support plate. The carrier is floated by an attractive force produced between the rail and the magnet units of the assemblies. A gap sensor of each of the assemblies generates an output signal corresponding to a gap between the rails and the magnet unit and a current supplied to the magnet unit is also detected by a current detector. The outputs from the gap sensor and the current detector is fed as feedback signal to an operational circuit of the control unit. Thus, the current supplied to the magnet unit is so adjusted by the operational circuit as to supply the current when an external force is applied to the carrier.

摘要： A plurality of stators of a linear induction motor are arranged at predetermined intervals, and guide rails are mounted on an upper portion of a track frame having a U-shaped section. A levitated object is magnetically levitated below the track frame so as to freely travel along the guide rails. Magnetic support units having electromagnets for obtaining a levitating force, optical gap sensors for detecting gap lengths between the support units and the guide rails, i.e., deviations in a levitating direction, and optical gap sensors for detecting deviations in a guiding direction perpendicular to a traveling direction of the levitated object are respectively arranged on the four corners of the upper surface of the levitated object. The length of each magnetic support unit is larger than the width of each guide rail. Each magnetic support unit is disposed such that the inner ends of the unit and the guide rail are aligned, and the outer end of the unit extends outward from that of the guide rail. A deviation between an output from each optical gap sensor and a corresponding reference value is fed back to a corresponding magnetic support unit, thereby controlling each electromagnet.
