New brush composition: Handles higher voltages and currents – improves motor efficiency. The new brush composition was developed by Helwig-Carbon specifically for use in WarP Motors™ and replaces formulations that were typically used for fork-lift applications. New brush design: “split brushes with pad” design handles higher voltages and currents – improves motor efficiency. These new brushes are being radius-ed by the manufacturer and will also provide quicker “seating”, quieter operation, and reduced arcing.
