Stator windings in a switched reluctance motor of an electric supercharger

摘要

An electric supercharger 9 comprises a compressor element 14 and a switched reluctance motor (SRM) configured to drive rotation of the compressor element. The SRM comprises a rotor rotatable about an axis of rotation, and a plurality of pairs of stator segments 3 each pair of stator segments comprises segments that are on opposite sides of the axis of rotation. Each segment comprising a stator wire 8 wound around a stator core 27 having a cross sectional shape that is substantially rectilinear. The cross sectional shape of the stator wires preferably is quadrilateral, square or rectangular shaped. Each stator segment may comprise a housing element connecting with adjacent stator segments to form circular cylindrical housing. The SRM preferably has three pairs of stator segments. A method of forming a segment in a SRM is also claimed.
