An electronically commutated motor has a rotor () that is rotatable about an axis (D), and it has a stator arrangement () 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 () arranged on edge. The latter are arranged in an insulating part (). Each of these busbars () has a central portion (), a first end portion () and a second end portion (). These busbars () are insulated from one another and are nested into one another in a manner that minimizes relative displacement thereof.

Electronically commutated motor with nested radially stepped busbars

An electric motor has a rotor () rotatable around a rotation axis () and has a stator () arranged around said rotor (), which stator is equipped with poles (to). Each pole has an individual winding (to), and the latter together form a winding arrangement () that serves to generate a rotating field. Arranged approximately concentrically with the rotation axis () is an arrangement having electrical connection elements (U, V, W, U', V&#x2032;, W&#x2032;). The latter are equipped with mounting elements (VW, U&#x2032;, V&#x2032;) to each of which an associated end of an individual winding is mechanically and electrically connected. A connection arrangement () has a plurality of conductors () each of which is connected, by means of a welded connection (), to the connection elements of the stator in order to electrically interconnect them in a predetermined fashion.
