摘　　要：直流控制电机的限流与稳速控制方式适用于转矩控制与扭矩测量。它具有控制简便、允许电机堵转,并能在扭矩测量时减少因转速变化引起的附加误差。文中给出了基本控制电路。并可以此为基础设计出新颖、实用的教学实践课题。The DC control motor control with cut-off current and speed stabilization can be applied to torsion control and measurement. It allows motor running stop up and torsion control easily. In the torsion measuring, it can reduce additive error due to rotational speed change. Basic control circuits are introduced. Based on it, novel practical topics in teaching practice can be designed.
