Step Response Characteristics of an Electromagnetic Suspension Utilizing the Opposite Drive Mechanism

Abstract

　This paper reports on the step response characteristics of an electromagnetic suspension which utilizing an opposite drive mechanism using magnets and coils that move continuously in opposite directions was verified by prototype. It was shown that damping time is shortened by operating the opposite drive mechanism, and the electric power about 2 times can be obtained. Moreover, it was confirmed that the damping force and the electric power corresponding to the electric load could be obtained in the actual running test in which the electromagnetic suspension is mounted on the small electric vehicle.
