The support further comprises a plurality of engagement means () formed between the teeth arranged to receive additional teeth () having wire windings mounted thereon. Preferably the engagement means are provided between adjacent teeth. The support and integral teeth provide a rigid structure while the spacing provided by using additional teeth makes it easier to wind coils.
