Piezoelectric ring motor e.g. electromechanical motor, adjusting method, involves calculating offset value from voltage values that are recorded based on signal characteristics evaluation when actuators are actuated, during motor operation

摘要

The method involves recording voltage values for a change of operating state between a stopper of a drive shaft and a drive ring of a piezoelectric ring motor and free movement between the stopper and ring based on the evaluation of characteristics of electrical signals when piezoelectric actuators are actuated. An offset value of the offset between the shaft and ring is calculated from the values during the operation of the motor.
