As a repair
shop, Electric Motor Company adheres to the highest standards available to the industry.
Equipment brought in for repair is disassembled and inspected for both mechanical and
electrical defects. The test results are recorded on job cards and stored for future
reference. Stators that are to be rewound are "burned out" in a Bayco
temperature controlled, pollution free oven. Winding data is taken and recorded. The
stators are then cleaned, dried, and insulated using Class H, NOMEX insulation. Coils are
made using 200° C copper wire.
The coils are then inserted
into the stator and connected as per data previously recorded. The lead wire used is
Sil-a-blend, Hypalon, or EPDM all rated at 600 volts. New windings are surge tested for
grounds, shorts, or faulty connections. They are then voltage tested for even phase
amperage draw. The stator is next dipped into varnish, removed, and baked. This process is
repeated several times to achieve thicker insulation. The stators are then cleaned and
prepared for assembly. The motors are assembled using high quality ball bearings (e.g.
SKF, Fafnir, FAG, or NTN). Bearings are heated to 225° F in an oven, which allows them to
slip on easily avoiding damage to the shaft or bearing. The housing or bearing is packed
with Chevron SRI grease. The assembled motors are then megged and test run at full
voltage. The completed motor is painted gray or a requested color.
