Resistively Graded Insulation System for Next-Generation Converter-Fed Motors

RESISTIVELY GRADED INSULATION SYSTEM FOR NEXT-GENERATION CONVERTER-FED MOTORS

General Electric Global Research – Niskayuna, NY

Results from a multi-physics finite-element model analysis will be used to design and optimize a new insulation materials system that improves voltage endurance by a factor of two, and with additional development, can enable 5-10% energy savings with the use of advanced silicon carbide (SiC) variable speed drives.
