WINDING INSULATION ARRANGEMENT FOR AXIAL FLUX MACHINES

摘要

A stator 20 for an axial flux machine such as a motor or generator. The stator includes a stator core 32 having a back plane 24 which in use is disposed perpendicularly about a rotational axis of the machine. A plurality of teeth 26 extend axially from the back plane so as to form winding receiving slots 28 between adjacent teeth. The stator also includes an electrical winding 30 including a plurality of coils 32, each coil being located about a tooth of the stator core and being electrically isolated from the stator tooth by means of an insulating former 34 having a shape which closely conforms to the shape of the stator tooth. The coils 32 are interconnected to form the winding 30. A method of constructing a stator is also disclosed.

1. A stator for an axial flux machine, the stator including:
a stator core having a back plane which in use is disposed perpendicularly about a rotational axis of the machine, and a plurality of teeth extending axially from the back plane and including a free end opposite the backplane, wherein a plurality of winding receiving slots are defined between adjacent teeth; and an electrical winding including a plurality of coils, each coil located about a stator tooth of the plurality of stator teeth and electrically isolated from the stator tooth by means of an insulating former having a shape which closely conforms to the shape of the stator tooth and having side covers configured to at least partially enclose each coil and electrically isolate each coil from side walls of adjacent teeth and/or adjacent coils, the coils interconnected to form the electrical winding.
