Abstract

An electronically commutated motor has a rotor (34) that is rotatable about an axis (D), and it has a stator arrangement (30) in which is provided a number, evenly divisible by three, of salient stator poles that are wound with winding strands, associated with which, for the connection thereof, are busbars (44, 46, 48) arranged on edge. The latter are arranged in an insulating part (42). Each of these busbars (44, 46, 48) has a central portion (78), a first end portion (90) and a second end portion (56). These busbars (44, 46, 48) are insulated from one another and are nested into one another in a manner that minimizes relative displacement thereof.
