We already proposed the method for efficiency measurement of the linear oscillatory actuator (LOA) with a load cell between a LOA and a load motor. However, output of load cell is not an accurate value, because the inertial force affects the load cell under high-speed reciprocating motion of the LOA. In this paper, we verify that the proposal method for efficiency measurement is appropriate by deducing equations of motion. Moreover the proposal method is verified by the both simulation and measurement. Output of load cell becomes larger than the accurate thrust in both simulation and measurement. However, the accurate mechanical power is equal with the proposal one. Therefore, it becomes clearness that the proposal method for efficiency measurement is appropriate.
