Abstract
The stator for an electrical machine comprises a laminated magnetic circuit 1 having a plurality of teeth delimiting longitudinally oriented slots, electrically conductive wires 2 being disposed in the slots, and winding heads 3 at the ends of the stator. An outer sheath 4 forms part of the final motor. The stator includes a composition 6 for impregnating the winding heads, of which the filler has a large particle size, and a slot-impregnating composition 8, containing a filler of smaller particle size.
