Most mechanical transmissions function as rotary speed changers.

大多数机械传动器的功能都作为转速变速器。

The rotary speed has no effect on the working load on cutting teeth.

转速对切削齿上的载荷分布基本无影响。

Critical rotary speed of the revamped driving shaft is also measured and analyzed.

并对改进后传动轴的临界转速进行了测定分析。

In a BLDCM, Hall position sensors (HPS) are usually used to detect the rotor's position and rotary speed.

在永磁无刷直流电机中，霍尔位置传感器经常用来测量电机的转子位置和转速。

The rotary speed control circuit adjusts the rotary speed of the fan according to the output electrical signal.
