We developed a new method for accurate estimation of the excitation force of an electric motor by inverse system using measured acceleration response. To solve this inverse problem, we employed an accelerometer to measure the accelerations of the supporting beams of the motor. In the experiment, the acceleration of a beam was measured when the motor was in operation. Additionally, the inverse system was created by using the equations of motion for both the motor and the supporting beams. The results obtained by this method agreed well with the results of the excitation force measured by using a load cell directly.
