diàn dòng jī zhuàn sù]
speed of rotation of motor
motor speed
- 通过改变变频器的输出电压可以控制被拖电动机的转速。
Variable speed motor drive (VSMD) is used to control the electrical machine by modifying the frequency of its output voltage. - 摘要抽油机中载荷变化大,易引起电动机转速和转矩的波动。
This paper mainly focuses on the fluctuation of velocity and torque of the electromotor because of the variational load in the pumping unit equipment. - 该系统可完成电动机的转速、转矩、轴输出功率等参数的显示及实时、历史曲线绘制,实时数据及历史数据的显示、查询、打印。
The system can carries out the protract , display, demand and mimeograph for real time and history datum of electromotor rev, torque, and output power ,etc, parameters.
