摘要： Electrical machine with a rotor with magnets carried by an annular carrier, in which a magnetic field is created over an air gap between two rotor parts, at which an ironless stator with windings is arranged. A space saving machine is achieved with a stator which is assembled of sections with channels for circulation of coolant, and which has windings with an annular, compact central part providing the active part of the stator. A method for manufacturing stator sections for such electrical machines is described, where a winding is embedded in an electrically insulating casting material for providing a rigid element. A coil is arranged in one part of a bisected shell housing or a bisected casting mold, and the shell housing or mould is closed, casting material is introduced through an opening and the inner part of the housing or mould is subject to underpressure and possibly vibration.
