<P>PROBLEM TO BE SOLVED: To provide a magnetic rotational transmission controlling device of a magnetic rotational transmission device in which a control means prevents seceding to always control to such rotational speed as corresponds to load fluctuation, for continuous rotational transmission at a maximum rotational speed at each time point although a slave magnet secedes, being incapable of following, if the rotational load of the slave magnet exceeds the magnetic rotational transmission force. <P>SOLUTION: The control means is provided with a magnetic detection sensor near a rotation region of a drive magnet or slave magnet in magnetic coupling. The magnetic detection sensor monitors the magnetic coupling state between both magnets, and transmits an output signal to the control means 11. The control means extracts and calculates the component of a magnetic deviation angle in the signal. A magnetic deviation angle error amplifying part 25 matches it with a limit magnetic deviation angle set value which is set in a safe region before seceding. The rotational speed is always controlled to keep the limit magnetic deviation angle for preventing seciding and the rotational transmission is continued at the maximum rotational speed corresponding to the magnetic deviation angle. <P>COPYRIGHT: (C)2004,JPO |
