More Information
Summary:A field coil (10) for an electromagnetic rotor comprising multiple windings (12), each substantially entirely coated with a powder resin having a dielectric strength of at least in the range of 1000-1500 v/mil. A method of manufacturing a field coil (10) for an electromagnetic rotor includes the steps of a) providing a field coil comprising multiple layers (12) of copper bars; b) coating the multiple layers (12) of the field coil (10) with a powder resin having a dielectric strength of at least about 1000-1500 v/mil.; and c) curing the powder resin.
