AI for electric motor repair shops, tried on shop orders you've already closed.

The trade's own practice starts with records. ANSI/EASA AR100, the Electrical Apparatus Service Association's Recommended Practice for the Repair of Rotating Electrical Apparatus, names record keeping ahead of tests and analysis in its scope, for induction, synchronous and DC machines. ANSI approved the 2025 edition on November 20, 2025, with 48 technical changes among its 72 revisions, and EASA gives it away as a free download. It also says it doesn't replace a customer's or maker's own specifications. So each order you've closed holds the sheet, the customer's spec and the document that followed, which gives your reviewer an answer key.

Utilities buy both outcomes at once. Fort Worth's 2023 invitation for its Water Department sought an annual agreement for electric motor repair and replacement, as needed. Lawrence, Kansas, got approval in 2013 to bid fifteen of its utility's 532 pumps and motors for rebuild or replacement, and its memo notes some were better replaced than rehabilitated. Tulsa's 2020 invitation for its Water and Sewer Department runs to motors of 3,000 hp and asks each bidder for a UL certification, ISO 9001:2015 and a vacuum pressure impregnation tank of at least eight feet. A shop selling to those buyers answers a written spec at both ends of every job.

The audit reads the paper. EASA's Accreditation Program sends an independent auditor through 23 categories and more than 70 mandatory criteria, checking repair documents or watching the work, on three-phase squirrel-cage motors. Its checklist moves from Version 4.1 to Version 5.0 for audits from January 1, 2027. Nothing in this proof of concept stands in for that audit. It does explain why the paper around a rewind gets as much care as the rewind.

Transformers and generators need a sample of their own. AR100 covers rotating machines. Transformers fall under EASA's AR200-2021, the Guide for the Repair of Dry-Type Transformers, which narrowed its 2011 edition to non-liquid-filled units with high-voltage windings up to 69 kV and ratings below 15,000 kVA, the work EASA says its service centers typically do. Its tests include turns ratio, polarity, and no-load and load loss, fields a motor sheet doesn't have. For a load test, AR100 cites IEEE 112 on polyphase induction machines and IEEE 115 on synchronous machines, so those jobs follow different documents as well. We'd test one kind of machine first.

The names on old paper have moved. EASA's notes on the 2025 edition say AR100 now cites NEMA MG 00001, the successor to NEMA MG 1, so older and newer files can name different documents for the same thing. Nameplates drift too: MG 1 set efficiency guidelines in 1977, published energy efficient ratings in 1989 and added premium efficiency ratings in 2001. EASA and AEMT, its British counterpart, report from a 2019 third-party lab study that premium efficiency motors can keep their efficiency through a good-practice rewind. A draft has to carry the label and reference your own paper uses.

One limit covers both jobs. The proof of concept works only on copies. It never touches your shop system, ERP or test equipment, and never a live quote or report. It doesn't decide whether a motor gets repaired or replaced, judge a test result or sign anything. A qualified person on your team makes every repair decision and signs every report. This page describes public documents and isn't legal or engineering advice.
