Abstract

A coil former for an electric motor, in particular a high-speed surgical motor, in which a rotor is surrounded concentrically by the substantially hollow-cylindrical coil former, carries at least one stator winding. To ensure that as narrow an air gap as possible is permanently maintained between the coil former, which is preferably produced using an injection-molding method often with complex shaping, and a rotor, which runs in the coil former, the coil former is formed either by a non-conductive fully ceramic body, or is in the form of a composite body in which at least one dimension-stabilizing frame element is embedded by injection-molding with plastic in a plastic body which is preferably produced by injection molding.
