USM

Introduces the theory and virtues of the developed TRUM 45 rotary USM.

介绍所研制的TRUM45旋转型超声电动机的工作原理及其优点.

However, tool wear is high in USM, due to the abrasive cutting action.

但是, 由于USM是磨削加工, 因而刀具损耗大.

I was a dedicated student, and I had my heartset on going to USM.

我是个执着的学生, 一心想上南密西西比州大学.

Based on contact pattern between the stator and rotor, USM as contact type and non-contact type.

根据电机定子和转子间能量传递方式,超声波电机分为接触型和 非接触 型.

Some of my friend graduated finally after few years studying in USM Penang.

我的一些朋友经过几年的“寒窗苦读”,终于毕业了.

Then a practical driving circuit for the USM is designed.

其次,设计了实用的USM驱动电路.

When selecting different resistance and inductance, variable frequency control of USM can be realized.

电路中选择不同的电阻和电感值可以实现调频, 即对超声波电机的变频控制.
