A genuine P&H motor brush is designed to withstand
- Extreme climate conditions
- Continuous motor operation with sudden changes between low-speed/high-torque and high-speed/low-torque
- Rapid direction changes between forward and reverse
- Variations in current densities
- High shock loads
- Machine vibration and more
Continuous improvement
If conditions warrant an alternative brush grade or configuration to match the motor's particular operating conditions, we can develop a solution to meet the specific need. That process typically consists of:
Monitoring
- Auditing of motor and brush performance
- Comprehensive inspections of the commutator and the commutator
compartment on operating equipment
Documentation
- Reporting of the physical condition of the commutator bar face and ends: indications of mine dust, oil, grease or other contamination exposure
- Evaluation and recording of the condition of the commutator's surface finish and polish, film color and uniformity, bar markings and the presence of copper-drag or flashover damage
- Calculation and graphing of brush wear rates, providing a quick visual reference and benchmark for future evaluations
- Photographic documentation
We employ all problem solving strategies as appropriate to cause minimal disruption to equipment operation while seeking optimal solutions to your challenges.
