Abstract:
An axial field rotary energy device (31) can include a housing (203). A rotor (33) can be mounted inside the housing. The rotor can include an axis (35) of rotation and a magnet (37). A stator (41) can be mounted inside the housing coaxial with the rotor. The stator can include a printed circuit board (PCB) (45) having a PCB layer (47) with a trace (49) that is electrically conductive. The trace can include radial traces (150) that extend in a radial direction relative to the axis and end turn traces (148) that extend between the radial traces. The trace can include slits (321) that extend through at least some portions of the trace.
Abstract:
The invention relates to a method and a rotor for producing a short winding head (6), in which conductor sections (5) of a rotor winding, emerging on the front side from the base body (2) of a rotor (1), are bent in the direction of a commutator (7). The conductor ends (14, 15) of the conductor sections (51, 52), which are aligned parallel to the axis, are placed in a second inner radial position from an original first outer radial position. Conductor sections (51) leading to the conductor ends (14) are bent over a bending edge (11) of a bending ring (10) placed on the front side on a base body (2) and are aligned at least approximately parallel to the front side (4) of the base body (2).
Abstract:
A method of manufacturing a motor for a power tool includes providing an armature configured to be coupled to a shaft. The armature includes a yoke and a first tooth and a second tooth that extend radially outward from the yoke to define a slot between the first tooth and the second tooth. Each of the first tooth and the second tooth include an inner end adjacent the yoke and an outer end opposite the inner end. The method further includes coupling a first wire guide member to the outer end of the first tooth, coupling a second wire guide member to the outer end of the second tooth, winding wire into the slot, after winding wire into the slot, compressing the wire radially into the slot, uncoupling the first wire guide member from the first tooth, and uncoupling the second wire guide member from the second tooth.
Abstract:
Ein Wicklungsträger (1) weist eine um eine Symmetrieachse (3) umlaufende, nach radial außen offene Wicklungsnut (2) mit einem radial innen angeordneten Nutgrund (4) auf. Auf den Nutgrund (4) wird eine erste Windungslage (8) eines Wicklungsdrahtes (7) gewickelt wird, auf die jeweils unmittelbar zuvor gewickelte Windungslage (8,9) weitere Windungslagen (9,10). Zumindest beim Wickeln der weiteren Windungslagen (9,10) wird jeweils mindestens eine Windung (14) der jeweiligen weiteren Windungslage (9,10) von einem ersten Windungsleger (12) und werden die jeweils übrigen Windungen (14) der jeweiligen weiteren Windungslage (9,10) von einem zweiten Windungsleger (13) gewickelt. Dadurch verlaufen sowohl die erste Windung (14) als auch die letzte Windung (14) der Wicklung (6) in der radial äußersten Windungslage (10).
Abstract:
A stator (2) for use in a slotless electric motor (1), particularly an electronically commutated motor, has a winding body (21) in the form of a hollow cylinder, consisting of three or more coils (26), and having a working section (15) located between two winding heads (23, 23') at two longitudinal ends of the winding body (21), and a cylindrical stator lamination stack (22), close-fittingly encompassing said working section (15) of the winding body (21). The two winding heads (23) consist of the longitudinal ends (28) of the three or more coils (26). They positively lock the stator lamination stack (22) along a longitudinal axis (19) of the winding body (21). The two winding heads (23) have the shape of a circular flange with an inner radius (rwh) essentially equal to an inner radius (rws) of the 10 working section (15) of the winding body (21).

Abstract:
Изобретение относится к области электротехники в части электрических машин. Способ намотки фазных обмоток статора многополюсной электрической машины заключается в том, что провод фазной многополюсной обмотки укладывают в пазы между зубами магнитопровода статора, поочередно слева и справа огибая каждый зуб магнитопровода статора последовательно сначала в прямом, затем в обратном направлении, таким образом формируя вокруг каждого зуба магнитопровода статора виток, состоящий из двух половин. Выводы начала и конца фазной обмотки перекрещивают между собой на зубе магнитопровода статора.
