| Abstract: | The mechanism and the system of phase modulation and speed governing for ultrasonic motor are respectively analysed and proposed.With the use of microprocessor control, the important part of principle for this system is researched.At the same time,its practical shift phase control circuit by voltage frequency switching, the circuit of power driving and magnifying,and the circuit of feedback checking are introduced. Experiments show that the system has good performances,for example,flat at low speed starting,good linearity, no switch off to exchange direction,wide area for adjusting speed by modulating phase and so on.In addition,this system can scan and track resonance frequency in real time way and maintain good performance of ultrasonic motor. |
