英文摘要：

One novel kind of tiny TRUM with the diameter of 10mm was presented and manufactured.For the prototype has the millisecond level response characteristics and small output torque,the load capacity of the tiny type TRUM can be obtained by analyzing the transient dynamics.By the signal acquisition system composed of optical encoders,NI acquisition card and virtual instrument software,the transient characteristics experiment of the prototype was conducted to acquire its speed,startup and shutdown time.The measured data was analyzed to calculate the torque characteristics of the prototype.Finally,the proposed method is validated by comparing the calculated results with the experimental data of the dynamometer.
