Technical field [0001] The patent of the present invention involves a repair device for rotating rotary wave ultrasound motors, which belongs to the field of ultrasonic motor technology. Background technique [0002] With the large -scale production of rotating rotary wave ultrasonic motors, it is necessary to detect the motor stator in production; the ultrasonic motor stator with a larger frequency of the two phases is repaired.Neither the existing equipment and technology cannot achieve the detection of rotating rotation wave ultrasonic motor fixed modal parameters and two -phase frequency consistency repair.At the same time, no relevant literature involves real -time detection of ultrasonic motor operating frequency and consistency repair of two -phase frequency. [0003] At present, the frequency detection of the stator work frequency is mostly an impedance analyzer or the Doppler laser vibration system.Neither of the above -mentioned devices can not realize the frequency of ...

AI Technical Summary

Problems solved by technology

Both of the above two devices cannot realize the online real-time detection of the two-phase frequency of the ultrasonic motor

Impedance analyzer can detect two-phase frequency, the test principle is as follows Figure 1A, but does not detect the peak position of the stator standing wave vibration of the ultrasonic motor, so it is impossible to determine the position of the micro-machining of the stator during repair

The Doppler laser vibration measurement system can test the peak position of the standing wave vibration of the stator of the ultrasonic motor. title="Figure 1B">Figure 1B; but the detection device is complex and cannot meet real-time detection

Consistency adjustment of stator modal frequency of rotary traveling wave ultrasonic motor, Journal of Nanjing University of Aeronautics and Astronautics, 2006, 5 (38): 605-606, In this paper, a manual punching device for two-phase frequency consistency adjustment is disclosed. Although the device can adjust the two-phase frequency consistency of the stator, it cannot automatically identify the stator standing wave peak, and the effect of self-regulation is limited. , dynamically calculate the machining allowance
