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. Additionally, the frequency characteristics of the sensor and waveforms at driving condition are measured and discussed. The measured results are compared with the simulation results. Thus, the effectiveness of the proposed method is examined. The proposed method is effective to acquire the instantaneous torque and radial electromagnetic force, this study enable to vibration and torque ripple reduction.
