How to solve the problem of unstable voltage of micro geared motor?

Miniature geared motor after a long period of operation, there are usually some unavoidable small problems, such as there will be unstable voltage, miniature geared motor if long-term voltage instability will cause damage to the motor, thus affecting the motor operation of a series of work, the next is a brief introduction to solve the miniature geared motor voltage instability

1. electromagnetic field regulation in the excitation control circuit: connect appropriate resistive loads in series on both sides of the resistor, such as incandescent light bulbs, using resistive loads in the resistance of the hotter and hotter to the resistor characteristics of the discrete system, so that the field resistance line and the excitation characteristics of the start and stop section have a large intersection angle, to obtain a significant intersection point with the full-load characteristics graph, which in turn will make the micro geared motor in the lower voltage will also have a good working point.

2. Pole gasket: In order to reduce the excitation EMF gap and achieve saturated frequency characteristics at lower excitation currents for small geared motors, a good permeable raw material is padded under the pole boot. This results in a smooth output voltage.

3. Use automatic excitation regulation device of generator set: The automatic excitation regulation device of generator set has excellent excitation characteristics, with constant no power, constant power and other regulation methods, which is very reasonable to improve the smoothness of system software and transient response working ability, and also can solve the reactive power jittering problem of generator set caused by output short circuit.

The above is the solution to the voltage instability of the geared motor, I hope it will help you, more related information, please feel free to consult Vshida micro motor
