【摘要】：提出了一种新式的无缆驱动磁致伸缩惯性冲击电机,该电机以Terfenol-D悬臂梁作为驱动元件,能实现较低驱动磁场下的步进动作。此外,对电机的结构和工作原理进行了分析,并根据电机结构建立了动力学模型,最后通过实验验证了所提出的模型。实验结果表明,电机的工作频率为5~45 Hz,最小步长为0.38μm,电机运动精度较高,且实现了无缆驱动。
[Abstract]:A new type of non-cable driven magnetostrictive inertial impulse motor is proposed in this paper. The Terfenol-D cantilever beam is used as the driving element to realize the step action in the lower driving magnetic field. In addition, the structure and working principle of the motor are analyzed, and the dynamic model is established according to the structure of the motor. Finally, the proposed model is verified by experiments. The experimental results show that the operating frequency of the motor is 545 Hz, the minimum step length is 0.38 渭 m, the motor motion accuracy is high, and the cable free drive is realized.
