ABSTRACT:
An electromagnet is disclosed. The electromagnet has a winding that is wet wound with an epoxy material filled with grains of a material having a high coefficient of thermal-conductivity. The entire winding is empotted dry in a similar epoxy having grains of the said material. Fins are connected to the outside of the dry empotment for carrying away heat transferred to the fins from the coil.
