Commutators
DC Commutators
Copper commutators for DC motors and generators
We build commutators piece by piece: hard copper bars are insulated with mica, clamped in steel rings, treated with heat and pressure, then finished on the lathe to a mirror surface. The result is a commutator that runs true from day one — for DC motors, generators and railway machines.
