摘　　要：毫米尺度的微电机日益受到人们的关注,但是电磁电机的复杂结构和静电电机输出微弱限制了它们的应用,相比之下压电微电机具有独特的优势,结构简单且功率密度高。文章分类介绍了直径小于10mm压电微电机的发展状况、小型化的关键技术、应用领域和发展前景。There is a increasing interest on millimeter piezoelectric micro -motors . However, its application is limited due to the complex construct of electromagnetic motors and a little output power of electrostatic motors. Piezoelectric motors are promising because of the unique advantages on simple construction and high power density. The development state, key technology, application fields and future of micro motor for diameter less than 10 millimeter are introduced in this paper.
