摘要： A method for producing an electric motor provided with a stator core configured by laminating a required number of annular electromagnetic steel sheets having a plurality of tooth portions on an inner periphery thereof. The circumferential widths of the tooth portions become gradually narrower in a stepwise fashion toward an uppermost surface and an undermost surface of the plurality of laminated electromagnetic steel sheets, whereby the shoulder portions on both sides in a circumferential direction of the tooth portions smoothly change. A flexible, planar insulating member is provided having a first portion of a shape similar to a planar shape of said electromagnetic steel sheet, and further comprising flexible ear portions at positions corresponding to shoulder portions on both sides in a circumferential direction of the tooth portions. A coil is wound around the flexible planar insulating member and the respective tooth portions, including the ear portions of said insulating member interposed between the coil winding and the tooth portion, to thereby deform the flexible ear portions to conform the shape of the shoulder portions.

摘要： A carrier for coils of an electric machine includes a rotation-symmetrical carrier stack having laminations with axial slots which are configured to receive a wire of the coils. Adjacent ones of the slots are separated from one another by a slot wall. The carrier stack has circular end faces and is formed with slot openings for the slots. Electrically insulating material is applied upon at least the slot walls of at least one of the end faces to cover the slot walls at their end face and to electrically insulate the slot walls.

摘要： An external rotor motor includes: a shaft, an insulator and a core. The insulator is coupled with an outer peripheral surface of the shaft, the core is arranged on an outer periphery of the insulator, and the insulator is formed between the shaft and the core, so that no electrically conductive route can be formed between the core and the shaft. A rotor has a housing rotatably coupling with the shaft, with an inner peripheral wall of the housing having a permanent magnet module.

摘要： A stator of a brushless motor may include a core; a bobbin including a pair of side surfaces, an inner wall, and an outer wall; a conductor wire wound by being overlapped in plural layers; and a resin layer covering the bobbin and the conductor wire. A profile of the conductor wire may become larger towards an outer circumferential side of the stator. Among portions of the conductor wire arranged along a rotary axis direction of a rotor on at least one side surface included in the pair of side surfaces and located on an innermost circumferential side of the stator in the respective plural layers, a portion of the conductor wire exposed to the resin layer and separated from the inner wall and the outer wall may be tilted from an inner circumferential side of the stator toward the outer circumferential side of the stator.
