What is the ideal pressure range for brush contact in a generator to prevent excessive wear and arcing?

The ideal pressure range for brush contact in a generator is typically between 0.5 to 1.5 pounds per square inch (psi). This range helps to ensure proper contact between the brushes and the commutator, while also preventing excessive wear and arcing. It is important to regularly monitor and adjust the brush pressure to maintain optimal performance and prevent damage to the generator.

0.25 to 0.50 psi (17 to 34 kPa)
