A stepping motor is used widely as an actuator for position control. However, there is adisadvantage in terms of efficiency because the motor is generally excited by maximum ratedvoltage. In this case, a problem of rotor oscillation also occurs by overabundant driving torque.In this paper, the authors suggest a new method for more efficient operation and dampingof oscillation.Generally it is difficult to build up a strict mathematical model of a stepping motor becauseof its nonlinearity characteristic. However, it is possible to investigate the relationship betweenexciting voltage and aspect of step response qualitatively by some simple experiments.Therefore, the authors use a method including fuzzy reasoning which is suitable to describequalitative relationship for decision of proper exciting voltage.The effectiveness of this method is presented by the experiment for an actual steppingmotor.
