An electromagnetic damper is a one of the semiactive dampers which can control a damping force, and has been researched a lot before. It has conventionally a DC motor in order to get a damping force for converting a rotational kinetic energy into an electrical energy by the motor and dissipating. The damping force can be controlled by switching a resistance of the motor terminal. In this paper, the authors propose to use a stepper motor instead of the DC motor to find some new performance. A proto-type damper using 2-phase or 5-phase stepper motor was manufactured, and the resisting force characteristics of the damper were measured during sinusoidal vibration. Finally, a performance of the damper was confirmed experimentally.
