Abstract
Open shaft electric machines protected by a) potting the stator windings in a solvent-free resin incorporating a filler having a high thermal conductivity, b) sheathing the potted component in a thermally insulating binder resin with a coefficient of thermal expansion similar to that of the stator metalwork, and c) an impermeable ceramic jacket. the surrounding casing is cooled to remove heat from the windings via their conductive resin matrix. Pref. stators are potted in polyester, epoxy, silicone or polyimide resins filled with various minerals, or polyamide or polyester resins; the sheathing is of phenolic, polyester, epoxy silicone or polyamide resins filled with powdered silica, C, B, Al, polyamide or polyester resins or mineral fibres, esp. epoxy resins containing 30 - 90% wt. glass. Claims ceramic jackets pref. 1.5 mm. thick, pref. impregnated with resins from those claimed for sheathing.
