Abstract
A stator according to the prior art is formed out of a laminated stack that is insulated by means of a plastic coating, and stator pole teeth are connected to each other in permeable fashion. A stator (20) according to the invention comprises separate permeable stacks of individual laminations (16) that are held together by means of a plastic coating. The return ring (30) is joined with play on the stack of individual laminations (18, 16, 1) and installed on the stack via bayonet coupling.
Claims13
A stator (20) comprising at least one stack of individual laminations (16) that comprises at least one lamination (1), and an at least partially present plastic coating (22), wherein the stator (20) comprises at least one corn ring (70) that forms a watertight inner channel (27) and extends along a centerline (3), wherein at least one stack of individual laminations (16) is located on the core ring (70), and the at least one stack of individual laminations (16) is held together by means of the plastic coating (22), wherein the core ring (70) is made of plastic and has at least one hook-shaped protection (77) for each stack of individual lamination (16) that extends in the direction of the centerline (3) of the stator (20) on an outer surface of the core ring (70), and the at least one hook-shaped projection (77) at least partially encompasses the stack of individual laminations (16) and forms a positive connection.
A stator (20) comprising at least one stack of individual laminations (16) that comprises at least one lamination (1), and an at least partially present plastic coating (22), wherein the stator (20) comprises at least one core ring (70) that forms a watertight inner channel (27) and extends along a centerline (3), wherein at least one stack of individual laminations (16) is located on the core ring (70), and the at least one stack of individual laminations (16) is held together by means of the plastic coating (22), wherein the core ring (70) has at least one protuberance (74) that extends in the direction of the centerline (3) on an outer surface of the core ring (70), and the protuberance (74) catches in a groove (58) of the stack of individual laminations (16).
