portable planetary geared electric motor wholesale is used in the process, there will often be voltage instability, will affect the work of the motor. Next, we introduce how to deal with the voltage instability of portable planetary geared electric motor wholesale.
1. Magnetic field regulation in the excitation circuit: A suitable resistive load such as an incandescent bulb is connected in parallel at both ends of the resistance. The resistance value of the resistive load after heating is changed to obtain nonlinear resistance characteristics, so that the field resistance line has a large intersection Angle with the excitation characteristic starting section, and an obvious intersection point with the no-load characteristic curve is obtained. Thus portable planetary geared electric motor wholesale at lower voltage will also have a stable operating point.
2, magnetic pole gasket: in the micro reducer pole shoe pad into the benign magnetic conductive material, reduce the excitation field gap, can make it in the small excitation current to saturate the output characteristics, so that its output voltage to achieve stability;
3, the use of generator automatic excitation regulation device: The generator automatic excitation regulation device has good excitation characteristics, with constant reactive power, constant power factor and other adjustment methods, which is very effective in improving the stability and transient response ability of the system. At the same time, it can solve the generator reactive power swing problem caused by portable planetary geared electric motor wholesale output voltage instability and system voltage fluctuation.
