Abstract

The invention relates to an insulation device (1) for electrically insulating a stator winding (21) of a stator (20) of an electrical machine with respect to a pole piece (22) of this stator (20). The insulation device (1) comprises a plate-like base (2), made of an electrically insulating material, preferably of an electrically insulating plastic, in which a substantially rectangular through-opening (3) is arranged, having two opposite narrow sides (4a, 4b) and two likewise opposite broad sides (5a, 5b). The through hole (3) is used to receive a pole piece of the stator (20). The insulation device comprises a base collar (10) integrally formed on the base, which extends along the two broad and narrow sides (4a, 4b, 5a, 5b) of the through opening (3) and encloses the through opening (3) in sections. The base (2) and the base collar (10) are thus formed in one piece and of the same material. The base collar (10) has in the region of the two narrow sides (4a, 4b) in each case an undercut (7a, 7b) forming a collar opening (6a, 6b). Furthermore, the insulation device comprises a (first) insulation element (7a), which is preferably plate-like in shape and is also separate from the base, for closing one (first) (6a) of the two collar openings (6a, 6b).
