  • This abstract for appeared for patent application number 18336194 Titled 'DRIVE CONTROL DEVICE AND ULTRASONIC MOTOR SYSTEM'

Simplified Explanation

The abstract describes a drive control device for an ultrasonic motor. The device includes a speed detector, a controller, and a drive circuit unit. The speed detector measures the motor's driving speed, while the controller sets the motor's drive conditions. The drive circuit unit applies a drive voltage to the motor's piezoelectric elements based on the drive conditions set by the controller. Additionally, the controller adjusts the drive conditions based on the accumulated operation time at each driving speed of the motor.


Original Abstract Submitted

A drive control device is provided that drives an ultrasonic motor element including a vibrating body and piezoelectric elements provided on the vibrating body. The drive control device includes a speed detector that detects a driving speed of the ultrasonic motor element, a controller that sets drive conditions of the ultrasonic motor element, and a drive circuit unit that applies a drive voltage to the piezoelectric elements based on the drive conditions set by the controller. Moreover, the controller sets the drive conditions of the ultrasonic motor element based on the accumulated operation time for each driving speed of the ultrasonic motor element.
