Study on Feedback Voltage Characteristics of Isolated Pole of Ultrasonic Motor
The performance of ultrasonic motor completely depends on its driving control system.In order to take advantage of the isolated pole characteristics of ultrasonic motor,the driving system needs to control the feedback signal of isolated pole.Aiming at the isolated pole feedback of ultrasonic motor,the characteristics of the isolated pole voltage of ultrasonic motor was first briefly analyzed in this paper,including the calcula-tion of the isolated pole voltage and the variables that affect the isolated pole voltage,and the existing isola-ted pole voltage of ultrasonic motor was tested to verify the correctness of the theoretical calculation,and then the feedback signal of the isolated pole voltage was to be dealt,and the feedback control was to be designed.Finally,the test results of the isolated pole voltage before and after adding the feedback signal were analyzed and compared.The experimental results show that the fluctuation of isolated pole voltage can be reduced ef-fectively by using the isolated pole feedback voltage of ultrasonic motor.
