THE IMPORTANCE OF SPRING PRESSURE

Spring pressure can have a dramatic effect on the life and performance of carbon brushes. As spring pressure lowers, the electrical wear rate of the brush increases.

In addition, very weak spring force can lead to bouncing and chatter of the brush on the riding surface. Inconsistent spring force can lead to selective action, increased dusting, chance for arcing, etc. This leads to increased maintenance and reduced brush life and can lead to damage to the machine.

Maintenance Tip:
Increase the life of your brushes by adding ‘Check Spring Pressure’ to your regular maintenance schedule. Detect issues with spring pressure before any damage is done to the brushes or motor.

To calculate Spring Pressure

Spring Pressure(P.S.I) = Measured Force(lbs) / Brush Thickness(in) x Width

spring pressue equation: spring pressure = measured force divided by (brush thinkness times brush width)

OPTIMAL SPRING FORCE

Refer to the chart below to calculate optimal spring force.

What Our Research Says About Constant Force Spring Differences

Many times, brush holders that use constant force springs are not constant force at all. A proper holder allows full spring force throughout the brush’s life. Most holders are poorly designed and fail to be “constant force” for two main reasons:
