电动电势 [diàn dòng diàn shì]
zeta potential
- 其次，本文提出一种转轴角度估测器，藉由侦测反电势，可获得微型电动机的转轴角度。
Next, a rotor position estimator is proposed. By detecting the back electromagnetic force (EMF), the rotor position of micro motor can be obtained. - 给出了开、闭环运行的实验结果对比，证明了利用谐波反电势实现混合式步进电动机闭环控制的可行性。
The feasibility of closed-loop control of hybrid step motor using the harmonic back EMF is proved by the comparative experiment between the open loop and the closed-loop. - 当电动机操作在中、高转速下，定子电流为连续时，可经由计算求出反电势，以获得电动机的转轴角度位置。
On the other hand, when the motor is operated in middle to high speed range, the stator current is continuous. The back emf can be computed. Finally, the rotor position can thus be obtained.
