What we take on
Single-phase and three-phase induction motors from 0.5 HP up to 100 HP: flour mill and chaff cutter motors, monoblock and openwell pump motors, compressor and lathe motors, fan and blower sets, and the three-phase motors on feed plants and cattle-feed mixers. Any make — the job is defined by the winding in front of us, not by the badge on the end shield.
What actually happens on the bench
The winding is megged to earth and checked phase to phase before anything is touched, so the fault is known rather than assumed. Then the old coils are counted out — turns per coil, wire gauge, coil pitch, number of circuits, star or delta — and written on the job card. The stator is stripped, the slots cleaned back to bare lamination and re-lined with fresh insulation paper. New coils are wound to the recorded data, inserted, laced, connected and tested for continuity and balance. It is varnished, oven-cured, fitted with new bearings, and the rotor checked for balance and shaft wear.
What we will tell you not to rewind
Not every burnt motor is worth the copper. If the laminations have burnt and lost their insulation the core will run hot whatever winding goes into it. If the shaft is scored at the bearing seat or the end shield housing has worn oval, the new bearings will not last the season. We say so and price a replacement instead, because a rewind that fails in month four costs you more than the one you did not buy.
How it is priced
On the copper it takes and the labour to put it in — so it follows the HP, the pole count and the wire gauge, not a flat rate per motor. That is why the figure comes after we have opened the terminal box and megged it, and before anything is stripped.
