New electromagnetic micromotor with a large torque

Micro electromachine system is mainly made up of microdriver. microsensor. microexecutor and microenergy.The microdriver, especially micromotor has a unique function in the micromachine system not only because it is animportant driver source in the micromachine system, but the micromotor it self is a typical micromachine system. Atthe beginning the micromachme system was researched, the micromotor is a central issue in the research. In view ofthe importance in the micromachine field and the possibility of developing into applied product of the micromotor,the research on the micro-motor is very important not only in theory but in practice.A very attractive trend on the research of micromotor is that, in the last, the researchers' work largely focus onreducing the dimension and little on the dynamic property of the micromotor. At present, people have put mainenergy on raising the property of the micromotor and began working of the micromotor's basic theory testingmethod and manufacture technology about the object. The research object comes from practical will do good to
