Resin applications using induction heat

An emerging method of curing resin coated stators and armatures is by the use of Induction Heating. This method of heating, although not new, is gaining momentum in the motor industry as a fast and precise method of heating and curing parts. This paper is a case study of the design of an Induction Heat Varnish Trickle machine designed for DC motor armatures. The study will cover the aspects of the design of the system including power supplies and optimizing coil design. Comparisons will be made during the study with more conventional heating systems (convection and infrared) showing the differences in heat up rates and efficiencies along with the floor space differences. A final comparison will evaluate the power requirements for the three different designs. Once this analysis has been completed, a summary will be provided for analyzing new applications to determine whether Induction Heating is a viable method of curing for a particular process.
