SUPER-SEALED MOTOR

Super-Sealed Motor A Super-Sealed Motor is a seven step moisture sealing process; We replace plugs with environmentally sealed plugs (if necessary); The stator is stripped to bare metal on the exterior; Then the surface is prepared and masked; The motor is then powder coated using polyester materials and baked for two hours; The motor is re-assembled with sealed bearings (not shielded); The end cover is assembled with a gasket sealer (particular brand from Japan not generally available) and finally we oil shield is installed;

ULTRA-KOTE

ULTRA-COAT;Ultra-Kote is a varnishing process that uses and H Class varnish to coat and seal the windings on an electric motor; The process thoroughly fills all slots and cavities and creates protection against contaminants; It also makes the winding 4 times more rigid, gives greater heat dissipation and extends the windings life;

ULTRA-SEALED WINDING

Ultra-Sealed Winding The process was developed to create total electric motor protection against moisture, prevent corrosion, improve heat transfer from the coils to the frame and enhance winding rigidity; The Ultra-Sealed Winding procedure involves insulating and sealing the winding through a mechanical and pressure process using a patented resin; An Ultra-Sealed Winding should not be confused with an encapsulated winding; Encapsulation only involves coating the coil ends, but when Ultra-Sealed, the coils are completely impregnated and sealed within high molecular weight thermoset polymer resin; There are two major advantages over traditional insulation methods; One is total protection against moisture; During in-house tests, windings have been completely submerged in synthetic cutting fluid for as much as 2 months without faulting to ground; The second advantage is more efficient cooling; The high molecular weight thermoset polymer resin is approximately 40 times more efficient at heat transfer than air;
