    • PROBLEM TO BE SOLVED: To provide a magnetic levitation device in which stabilized levitation control can be performed at all times while taking account of the impact of rolling of a levitation body on the estimated value of coil resistance. SOLUTION: A resistance measurement 140 operates the resistance of a coil; based on the output from a section 125 for operating an excitation voltage value for stabilizing a magnetic circuit formed of a magnet unit 107, based on the value i z of a current flowing through the coils 119, 119' of the magnet unit 107 detected at a sensor 123, and a coil current value obtained from the sensor 123; and the variation rate of air gap in the magnet unit 107 opposing a guide 113 estimated at a posture estimator 133 as a variation rate detector. Based on the operation results, levitation control is performed at the posture estimator 133 and the excitation voltage operating unit 125. COPYRIGHT: (C)2007,JPO&INPIT

    • PURPOSE:To stabilize the controlling performance of a magnetic levitation system by controlling an air gap length between an electromagnet and a guide rail always constant. CONSTITUTION:A conveying vehicle 22 levitates on a guide rail 22 by a magnetic attraction force produced between a magnetic supporting unit 23 placed on the vehicle 22 and a guide rail 21. A linear induction motor 25 is composed of a conductor plate 26 secured through a support plate 24 to the lower surface of the vehicle 22 and a stator 28 secured to a base. The unit 23 has electromagnetic coils 38, 39 and a permanent magnet 40. A controller controls so that the output of a gap sensor 51 for detecting an air gap length between a magnetic support 33 and the guide rail 21 becomes constant. Thus, the controlling performance of a magnetic levitation system can be stabilized.
