设计、制作并测试了微型直线同步电机。通过定子上微线圈线性阵列产生的行波与转子上永磁体的相互作用实现驱动。对电机的两种结构进行了研究。一种是在转子上手工组装单个永磁体和相应的多匝微线圈阵列；另一种是完全微加工的转子，其中嵌入了丝网印刷永磁体阵列和定子上的蛇形微线圈线性阵列。采用燕尾微关节对转子运动进行约束。建立了数值模型进行建模和动态控制。在开环和闭环控制下对电机进行了各种工况测试。电机显示可靠的翻译超过6厘米的行程与精度有限的反馈系统。
A miniature linear synchronous motor was designed, fabricated and tested. Actuation was achieved through interaction of traveling magnetic wave, generated by linear array of microcoils on the stator, and permanent magnets on the rotor. Two configurations of the motor were investigated. One with a single hand-assembled permanent magnet on rotor and corresponding array of multiturn microcoils; the other, a fully microfabricated rotor with embedded array of screenprinted permanent magnets and a linear array of serpentine microcoils on the stator. Motion of the rotor was constrained by dovetail microjoints. A numerical model was developed for modeling and dynamic control. The motor was tested under various operating conditions with both open- and closed-loop control. The motors showed reliable translation over 6cm travel with accuracy limited by the feedback system.
