An application of the finite-element method to force calculations is proposed. The force is determined by utilizing the magnetizing currents and flux densities on the line-forming elements. The method has been applied to a model of a permanent-magnet-type synchronous motor. Theoretical and test values of the model are shown to be well matched, demonstrating that this method is effective for highly accurate calculations of force and torque. The method has the additional advantage that the force distribution acting on the object is obtained.>
