ELECTRIC MOTOR REPAIR and REWIND

When repair/replace decisions are in doubt?

Trust us, our repair estimates are relatively straight forward before going further, we check

which is economical and practical, causes of failure, re-evaluate the application and operating

conditions of motor. Because there are opportunities to improve motor performance or

reduce operating cost. We will suggest or advise you in making a right decision.

We verified winding data of rewound motor (non original winding)

with a computer verification program.

We can also redesign the winding to better fit the motor application.

Repair and Rewind low voltage AC electric motor from fractional through 750 KW

Electric Motor Rewind Process:

● Proper winding removal to prevent core loss which causes loss of motor efficiency.

● Core loss testing to insure efficiency.

● Class F or H Insulation system to provide long motor life and service.

● Slot liner and phase insulation are Nomex.

● Premium grades high temperature inverter duty magnet wire which improved

resistance to the damaging effect of corona discharge.

● Coils wound on winding equipment for quality and consistency into the stator slot

by skilled craftsmen.

● Solventless varnish for outstanding resistance to chemicals and moisture with

superior physical properties.

● Double dip-and-bake cycle using resin varnish and heated on a temperature controlled

bake oven to ensure proper penetration into the form coil.

● Proper quality bearings and higher temperature lubricant to avoid bearing damage that

shortened motor live.

● Detailed inspection of all mechanical and electrical parts for soundness.

● Complete testing including a full voltage run and insulation test, well-documented

quality assurance systems and repair history.
