With the increase of pressure, the contact area between brush and commutator increases and the contact resistance decreases and leads to the decrease of contact voltage drop. 随压力增加,复合材料电刷和换向器的实际接触面积增大,接触电阻减小,电刷的接触电压降下降;
Develop of No Carbon Brush, No Contact Point, Compensation Type Electric Voltage Stabilizer 一种无碳刷、无触点、补偿式电力稳压器的研制
