How to keep the voltage of DC geared motor
The stability of the voltage directly affects the use of the equipment, especially equipment such as DC geared motors that are powered by electricity. How can you ensure that the voltage used is stable when used?
1. Use the generator automatic excitation adjustment device, because it has good excitation characteristics, and has a variety of adjustment methods such as constant reactive power and constant power factor, which can effectively improve the transient response capability and system stability.
2. A suitable resistor is connected in parallel across the resistance of the DC geared motor, and the non-linear resistance characteristic is obtained according to the resistance value change of the resistive load after heating, so that the field resistance line and the initial section of the excitation characteristic have a large intersection angle. An obvious intersection point with the no-load characteristic curve, so that the DC geared motor will also have a stable operating point at lower voltages.
3. A benign magnetically conductive material can be placed under the pole pole shoes to reduce the gap of the excitation magnetic field, so that the output saturation characteristic can be achieved under the condition of a small excitation current, thus ensuring the stability of the output voltage.
It should be said that proper operation has a very important effect on the voltage stability of DC geared motors. Before use, its inspection, detailed handling, and grasp of various parameters and standards are very important.
