1. The carbon brush must ensure a certain thickness.
2.When the carbon brush has not completely removed the turn of the coil that has been in contact, the carbon brush has touched another turn of the coil.
3. Two turns must be bridged during movement (at least two turns)
4. There is always a short circuit between turns during the operation of the voltage regulator. The thicker the thickness of the carbon brush, the more short-circuit turns. Therefore, the thickness of the carbon brush of the AC small voltage regulator is different according to the diameter of the voltage regulator. of.
5.Because the short circuit between turns is harmful and unhelpful, it will cause short circuit circulation, so the size of the AC small voltage regulator must be controlled, so the turn voltage of the voltage regulator is generally below 1V, the common high-power voltage regulator turn voltage It is 0.8-0.9V, and the low power is smaller, generally 0.4-0.7V. If the turn voltage is too high, the stability of the voltage regulator will be worse and it will be easily burned.
