摘　　要：上海交通大学在研制成　２ｍｍ电磁型微马达后，又在１９９９年成功地研制了 １ｍｍ电磁型双定子微马达。本文介绍了　１ｍｍ微马达的结构特点，对它的稀土永磁转子及 气隙磁场进行了分析讨论，还介绍了它的应用发展。After the success of the eletromagnetic micromotor with diameter of 2mm, Shanghai Jiaotong University has successfully developed a 1mm electromagnetic micromotor with bi-stators in 1999. In this paper, the structural features of this motor are described,the rare-earth permanent magnetic rotor and gap field are analysized and discussed, and its application and development are also introduced.
