Industrial DC motors

Commutators for industrial DC motors and generators

Beyond vehicles, the same commutators go into DC motors on lifts, cranes, printing presses, machine tools, winches and traction equipment. Rewind shops buy from us when the OEM part is obsolete or the lead time from the manufacturer is measured in months.

What we see with industrial dc motors starters

  • Lift and crane motors, conveyor drives, machine tools, pumps, hydraulic power packs
  • Supplied to rewind shops and maintenance engineers; trade accounts available
  • For anything over 120 mm diameter, send a drawing or the old part and we will quote
Which size fits? It depends on the exact starter or motor model. Send a photo of the commutator and the number on the armature and we will match it.

Not sure which one you need?

Send a photo of the commutator and the number stamped on the armature. We match it against the drawings we hold and send a firm price within 2 working days. If it isn't a standard size, we make it to measure. For industrial armatures, use the full data sheet, which takes a drawing and the V-ring dimensions.
