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.
