Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a control device for a magnetic attraction moving body to control a magnet such that the fluctuation of an amount of magnetic flux, fed to the magnetic body serving as an object to magnetically attracted, is accurately detected and a given amount of the magnetic flux is fed to the magnetic body. SOLUTION: A control device for a magnetic attraction moving body comprises a magnetism feeding means 3 to form a magnetic circuit 9 between a magnetic body 1 to be rub and the magnetism feeding means; a magnetism feed amount varying means 22 to vary an amount of magnetism fed to the magnetic body 1 of the magnetism feeding means 3; a magnetic sensor 4 to detect the leakage magnetic flux of a magnetic circuit 9; and a control means 21 to generate a control signal to the magnetism feed amount varying means 22 from a magnetism feed amount and a detecting value from the magnetic sensor 4 so as to generate a given attraction force. |
