摘要
超声波电机是以摩擦力作为驱动源的新型电机。阐述了其摩擦磨损机制,从力学的角度分析了超声波电机产生非线性的原因:一是定子与转子之间基于摩擦的非线性接触,使得超声波电机系统具有跳跃、滞后等特性;二是温度、磨损等导致电机材料特性和电机输出特性的变化。指出只有提高超声波电机的线性度和稳定性,才能提高它的输出功率,延长其使用寿命。
Ultrasonic motor（USM） is a new type motor,which applies frictional force as the driving source. Its mechanism of friction and wear was expounded. The causes that USM produces nonlinear was analyzed from mechanics angle, which is the nonlinearity due to the stator-rotor contact based on friction makes the USM system have jump and hysteresis characteristic, and the temperature and wearing result in the change of material and motor output properties. It is pointed out that the method to raise the output power and extend the life of USM is to improve linear character and stability of USM .
