We have established, through our accreditation program, a complete and rigorous set of procedures to ensure proper reconditioning of your failed equipment. Failed stators are core loss tested before and after the burn-off phase, in a precisely temperature controlled oven. This will ensure that the core iron meets or exceeds the testing procedures and standards within the industry. When it is determined that the stator has passed all the preliminary and core iron testing, the rewinding phase can begin. Insulation is prepared and added to the stator slot. Coils are manufactured to original specifications and tested for proper fit in the stator slot. When all the insulation materials and coils have been installed, the technician then starts the connection process. Extreme care is taken to make concise connections that can then be properly insulated before the tie-down procedure begins. Both ends of the winding are secured and the stator is prepared for the VPI process.
We use Vacuum Pressure Impregnation (VPI) to integrate the resin forming a void-free insulation system. Our VPI tank is 8 foot in diameter, 8 feet deep. The VPI process is documented as to the temperature and curing time to provide a complete insulation system. Which is capable of handling high temperatures, environmental contaminants, and vibrations that shorten the life of motor windings by degrading the insulation on the copper wire. The final product is a complete “Class H” insulation system that will handle higher temperatures associated with today’s duty cycles, inverter voltage spikes, and environmental contamination.
Our complete “Class H” insulation system and VPI process lead the industry.
