Outline of Final Research Achievements

Various magnetic suspension systems with mechanical control has been verified. The feature of these system is no use of electromagnets for levitation control. A variable flux path control mechanism has been developed by using a circular permanent magnet, magnetic cores, and a dc servo motor with a reduction gear. The suspension system using this mechanism can suspend two iron balls simultaneously. And some multi-degrees of freedom suspension systems with mechanical control magnetic suspension system are verified.
A non-contact slider system with mechanical non-contact power supply system has been proposed. It uses open-end generator. We studied about suitable design of the generator for zero-power control method.
