AC/DC Motor and Generator Rebuilding

Motor Technology's capabilities include the repair, reconditioning and rewinding of any type and size of AC or DC motor.  Failed stators are core loss tested before and after the burn off in a precisely temperature controlled oven.  This will ensure that the core iron is of a quality to meet or exceed the rigorous testing procedures.  When it is determined that the stator has passed all testing it’s then that the rewinding 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 readied for the epoxy resin application.  Motor Technology uses a process known as vacuum pressure impregnation (VPI) to apply the resins to the stator and copper windings.  This process is documented as to the temperature and curing time to provide a solid mass capable of handling high temperatures, environmental contaminates and vibrations that shorten the life of motor windings by reiterating the insulation on the copper wire.  After the stator comes out of the curing oven it is again inspected for any defects before the last process of covering the end turns with an extra coat of resin.  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 contaminates.

Motor Technology's Five Year Platinum Warranty on motor windings is the measuring tool for the rest of the industry.  Our complete "Class H" insulation system and VPI insulation process leads the industry.

Final testing to determine the quality of repair is essential for any customer.  Motor Technology has the ability to test run motors at full voltage up to and including 4160 VAC.  During the test run procedure, technicians are monitoring every aspect of the equipment operation.  This data is then incorporated into special reporting forms that are then emailed to the engineering staff at the customer location.  This detailed report is an excellent tool to document equipment repair history.
