Electromagnetic force acquisition distributed in electric motor to reduce vibration

A target of this study is the instantaneous electromagnetic force acquisition in the stator side to reduce the vibration. In this paper, the electromagnetic force is acquired from the displacement measured by the strain gauge. By using the switched reluctance motor which has salient poles, the displacements on both the stator and the rotor are measured. The measured results are compared with the simulation results and experimental results measured by an acceleration sensor. Thus, the effectiveness of the method is examined.
