Does the allowance cover lead connection time?

Yes. Lead connection, lacing and station setup sit in the allowance, so it is a percentage of base winding time rather than a flat adder. If your crew measures a different share, enter that share.

Why report base hours beside required hours?

Base hours isolate the winding work from setup and lacing. That split lets a planner quote the work content at the station rate and carry the allowance as setup cost, which usually behaves differently in a schedule.

What winding rate should I enter?

Use the rate your station sustains over a full run with the actual winding pattern, not the fastest observed coil. A time study on the same stator design gives the best figure.

Can one station wind more than one stator design?

Yes, but each design change carries its own setup. This page models one design per run, so for a mixed run calculate each design separately and add the hours and allowances.

Motors, Generators & Electrification Equipment calculator

Stator Winding Labor Calculator

Estimate winding hours from the stator count, the rate one station holds and a setup and lacing allowance. The result separates base time from the allowance so each can be planned on its own.

What this calculator does

Required winding hours for a stator run from the stator count, station rate and setup and lacing allowance.

Formula used

Base winding hours = stators to wind ÷ winding rate per station
Setup and lacing hours = base winding hours × allowance ÷ 100
Required winding hours = base winding hours + setup and lacing hours

Inputs explained

Stators to Wind This Run: Stators entering the winding run, counted as whole units.
Winding Rate per Station: Stators one station completes per hour, from a time study.
Setup and Lacing Allowance: Setup, lacing and lead connections as a share of base winding time.

How to use the result

Best suited to quoting a stator rewind batch, scheduling a winding station, budgeting setup and lacing hours.
Stator design changes, winding rework and lead repairs add hours outside the allowance. A rate measured on one station may not hold for another station or winding pattern.

Current U.S. benchmarks

The producer price index for primary nonferrous metals (a broad metals benchmark, not copper alone) stands at 544.731 (BLS, Aug 2026), up 49.3% from a year earlier. Quotes priced off last quarter's material cost miss this move. Global copper trades at $13,543 per tonne (IMF via FRED, Jul 2026).
Steel mill PPI stands at 381.162 (BLS, Aug 2026), up 23.4% from a year earlier. New factory orders are up 8.5% year over year (Census).
The U.S. has 5,397 electrical equipment and appliances establishments employing about 369,437 workers (Census County Business Patterns, 2023).
