 高于或低于电位计设置。功率因数调节功率因数调节对于需要强制磁场的应用来说是一个很好的选择，强制磁场是在短时间内应用高于额定值的直流励磁。许多驱动器，如削片机，在短时间间隔内会受到多次电机额定值的瞬态冲击过载。通过强制磁场，同步电机可以提供高于额定值的轴扭矩，而无需“退出”同步并停机。GE对削片机驱动器的测试表明，功率因数调节选项可以提供快速强制磁场功能，以防止破坏性电机“拉出”。功率因数调节的原理是电机运行功率因数是电机拉出的良好预测器。在电机失步之前（由于进入削片机的硬原木或超大原木的高轴负载），功率因数在滞后方向急剧下降。通过设置调节器，使其在功率因数下降超过调节器设定点时提升励磁，电机运行功率因数保持在“健康”水平，并避免电机“拉出”。功率因数调节还允许在电机轻载或空载运行时节省励磁功率。这不仅可以节约能源，还可以对电机绕组进行更深的空载冷却，因此电机运行时温度更低Above or below the potentiometer setting. Power factor regulation Power factor regulation is a good choice for applications requiring forced magnetic field. The forced magnetic field is to apply DC excitation higher than the rated value in a short time. Many drives, such as chippers, are subject to multiple transient impact overloads of the motor rating in a short time interval. By forcing the magnetic field, synchronous motors can provide shaft torque higher than the rated value without "exiting" synchronization and stopping. GE's testing of the chipper driver showed that the power factor adjustment option provides a fast field forcing function to prevent destructive motor "pull-out". The principle of power factor regulation is that the power factor of motor operation is a good predictor of motor pull-out. Before the motor is out of step (due to the high axle load of hard logs or oversized logs entering the chipper), the power factor drops sharply in the lagging direction. By setting the regulator to raise excitation when the power factor drops beyond the regulator set point, the motor operates at a "healthy" power factor and prevents the motor from "pulling out". The power factor adjustment also allows saving of excitation power when the motor is running with light load or no load. This can not only save energy, but also conduct deeper no-load cooling on the motor winding, so the motor runs at a lower temperature
