Made to drawing · UK company
Commutators made to your drawing. For DC motor rewinds.
For the rewind shops that keep Britain's DC motors running: industrial, traction, lift, crane and mill armatures, including the large ones that cost the most and take the longest from the usual suppliers. Starter and alternator sizes too. Price on request within 2 working days, in pounds, with one UK VAT invoice.
Standard 4 to 5 weeks by sea · Urgent air freight available · One off or in batches
What we make
New commutators for armatures being rewound or repaired. No original part needed: a drawing, or the old part's dimensions and a couple of photos, is enough.
Industrial DC commutators

The dimensions we work from
If you have them, the numbers on the diagram are the ones the factory needs. If you don't, a drawing or two photos of the old part does the job and we take it from there.
1 segments · 2 commutator diameter · 3 riser diameter · 4 diameter over V-ring · 5 bore · 6 total copper length · 7 brush surface length · 8/9 front and rear V-ring extension · 10 riser width · 11/12 slot width and depth.

Open the full data sheetFor rewind shops
A second source for the part you can't get quickly or cheaply.
Most UK rewind shops have one supplier for commutators, a long lead time and a price that has crept up for years. We give you a UK company to deal with, a firm price within 2 working days and a part made to your drawing.
What rewinders put up with today
- One supplier, long lead times, and a price that keeps rising
- Or import it yourself: euros, duty, a courier bill and no UK invoice
- Quotes that take days when the motor is already on the bench
- Nobody checks the drawing, so a wrong part turns up weeks later
