摘要:
通过有限元方法分析频率、电压、相位差3种调节方式对定子振型影响.结果表明:当驱动频率远离工作模态的谐振频率时,由于非工作模态对定子振型的影响,电机低转速运行会出现不连续现象; 过低的相位差则会造成定子应力集中,影响电机寿命; 在电机低转速运行时,通过电压调节则可以避免以上问题.以直径60 mm行波超声波电机为例,通过构建以DSP芯片TMS320F2812为核心的控制器,进行实验验证,实现电压调节时的电机低转速控制.
Abstract:
There are three methods in speed control of traveling-wave ultrasonic motor(TUSM), including driving frequency, voltage and phase difference. Through the finite element method, the vibration model can be analyzed in different driving frequency. As a result of the non-work model’s influence, the movement of TUSM is chopping in low speed when the driving frequency is far away from the resonance frequency of the work model. The stator stress is centralized in the excessively low phase difference. That affects the life of TUSM. In low speed control, the above question can be avoided through the voltage regulation. A 60 mm-diameter TUSM was used in this research. Using DSP(digital signal processor)chip TMS320F2812, a control system of USM(ultrasonic motor)was built. The system realizes the low speed control of TUSM by voltage regulation. The result confirms this method.
