<p>An electromagnet comprises a back plate, a circular bottom plate and a wear plate supporting the bottom plate. A shell is disposed between the back plate and the wear plate and is fixed to the back plate. Heat dissipation fins are disposed between the back plate and the wear plate and adjacent the shell. The fins extending radially outwardly from the shell. A winding is disposed in the shell adjacent the back plate. The winding and the shell define a space there-between the space being filled with an epoxy material that is filled with grains of material having a high coeffnt. of thermal conductivity.</p> |
