Three-phase induction motor repair
TEMISA repairs, rewinds and maintains medium-voltage three-phase induction motors (2.3 to 13.8 kV), both squirrel-cage and wound-rotor. The service covers the electrical side (rewinding under ANSI/EASA AR100, IEEE 43 tests) and the mechanical side (bearings, shaft, dynamic balancing), with a root-cause diagnosis before any work.
Scope
What the service covers
- Squirrel-cage and wound-rotor (slip-ring) induction motors.
- Rewinding with original design data, Class F/H insulation and VPI.
- Diagnosis: insulation, polarization index, surge and rotor tests.
- Mechanical work: bearings, shaft repair and dynamic balancing per ISO 21940.
Credentials
Who does the work
- CFE LAPEM qualification
- Supplier qualification certificate 053/26 (specification W6000-20, motors), issued February 20, 2026, valid through May 20, 2027; report R-N01328-9; Talleres Electromecánicos Industriales Sainz, S.A. de C.V., Tlajomulco plant. Literal scope: in-plant service to motors at rated voltage up to 1.5 kV; from 150 to 6,500 HP it includes coils; from 6,500 to 15,000 HP it is limited to cleaning, varnishing, testing and mechanical work; dynamic balancing approved up to 15 t. It is a credential, not the limit of the service offer (medium- and high-voltage motors above 1,000 V, subject to nameplate review).
- Quality management and repair process

FAQ
Frequently asked questions
Other questions: write to ventas@temisa.mx and an engineer will answer.
Do you accept low-voltage motors?
No. We accept industrial medium- and high-voltage motors only. Low-voltage motors (1,000 V or less) are outside our service scope. Send the nameplate for review before arranging shipment.
Do you repair the squirrel-cage rotor?
Yes. Broken bars and end-ring faults are assessed and repaired when the rotor is recoverable, and the rotor is balanced after the repair.
Which motor brands do you service?
TEMISA is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
