Electronically commuted electric motor and method for production thereof
TLDR
In this paper, an electronically commuted electric motor comprises an inner stator (18) and an outer rotor (24), separated by an air gap (23), and a circuit board (68) provided with recesses (58, 70, 72') is arranged on the inner stators.Abstract:
An electronically commuted electric motor comprises an inner stator (18) and an outer rotor (24), separated by an air gap (23). A circuit board (68) provided with recesses (58', 70', 72') is arranged on the inner stator (18). The inner stator (18) has a lamination bundle (22), provided with a winding arrangement (60; 86, 88), the connections of which are at least partly embodied as wire sections (86E, 88E, 90). The lamination bundle (22) of the inner stator (18) is at least partly covered by an insulation layer (20) made from a thermally-stable plastic. Support elements (58; 70, 72) are embodied thereon, extending from the inner stator (18) in the direction of the circuit board (68) which serve for the fixing of the wire sections (86E, 88E, 90) of the winding arrangement (86, 88). Said support elements (58, 70, 72) with the wire sections arranged thereon are each arranged in a corresponding recess (58', 70', 72') of the circuit board (68) and soldered to the same therein.read more
