摘要： PROBLEM TO BE SOLVED: To provide a driving equipment and a driving method of a piezoelectric actuator wherein crack and fracture are not generated in the piezoelectric actuator when the stroke of the piezoelectric actuator is sufficiently operated. SOLUTION: This driving method of a piezoelectric actuator has a safe region setting process for setting a safe region Vlim1 , and a driving process for applying a voltage to the piezoelectric actuator. In this safe region a 180 degree domain inversion amount (thick formed part) of piezoelectric material at either one out of a positive and negative applied voltages to the piezoelectric actuator is at most 1/3 of the whole 180 degree ferroelectric inversion amount S1 (shaped portion). In the driving process, and applied voltage is limited within the safe range Vrange1 . In the safe region Vrange1 , the applied voltage is generated. Temperature compensation is performed at need. Since the 180 deg. ferroelectric inversion amount is limited, local stress concentration in the piezoelectric actuator is little, and the capability of the actuator is maximumly exhibited in the range wherein crack and fracture are not generated.
