Abstract: A stator (2) for use in a slotless electric motor (1), particularly an electronically commutated motor, has a winding body (21) in the form of a hollow cylinder, consisting of three or more coils (26), and having a working section (15) located between two winding heads (23, 23') at two longitudinal ends of the winding body (21), and a cylindrical stator lamination stack (22), close-fittingly encompassing said working section (15) of the winding body (21). The two winding heads (23) consist of the longitudinal ends (28) of the three or more coils (26). They positively lock the stator lamination stack (22) along a longitudinal axis (19) of the winding body (21). The two winding heads (23) have the shape of a circular flange with an inner radius (rwh) essentially equal to an inner radius (rws) of the 10 working section (15) of the winding body (21).
