Industrial electric motor repair
TEMISA repairs industrial medium- and high-voltage electric motors, starting with a root-cause diagnosis and following with electrical and mechanical repair: windings, connections, bearings, babbitt journal bearings and shafts. The motor is tested before release, and the report records the cause of failure and the recommendations to prevent a repeat.
Scope
What the service covers

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.
What do you need to quote a repair?
The motor nameplate, photographs, the failure symptoms, the operating conditions and any previous test reports. Scope is confirmed after inspection.
Do you repair any motor brand?
Yes. TEMISA is an independent multi-brand service shop; the manufacturer's name identifies the equipment serviced.
What tests are run before delivery?
The tests agreed in the scope, typically insulation resistance and polarization index (IEEE 43) and surge comparison (IEEE 522), with the results recorded in the report.
Request for quotation
Medium- and high-voltage enquiries
Provide the motor type and nameplate voltage above 1,000 V. Low-voltage models shown in the reference archive are not accepted. A nameplate photo and failure details help define the scope.
