The excitation force of an induction motor is composed of many peak frequency components. The highest peak of the force appears at a frequency of 100 Hz, which is twice the power-supply frequency. We called this frequency component an "2 f component", and analyzed the force of this 2 f component. When the motor is in operation, the torque of the motor fluctuates at twice the power- supply frequency. This torque pulsation is cause of the excitation force of the 2 f component. Based on the mechanism of excitation-force generation, we developed a method for estimating the excitation force of a motor. Using this method, the excitation force of the motor was estimated from both the equivalent circuit and finite-element model of the motor. The results obtained by this method agreed well with the results of the excitation force measured by using load cell.
