Abstract:
The invention relates to a motor, especially an electronically commuted direct current motor, comprising a stator (2), designed as a hollow body, in which a rotor is fixed so as to be rotatably mounted, and a motor housing (20) which accommodates the stator/rotor unit. According to the invention, receptacles (8 to 18) for fastening elements (22) are provided on the stator (2), by means of which fastening elements the stator (2) is screwed to the motor housing (20).
Abstract:
The invention relates to an electric machine, comprising a rotor (8; 50; 76) and a stator (9; 29; 77), wherein the rotor (8; 50; 76) and/or the stator (9; 29; 77) comprise at least one laminated core (2; 11; 32; 72) having a substantially rectangular cross-section, wherein the laminated core (2; 11; 32; 72) comprises a sheet metal strip (1), wherein the sheet metal strip (1) is wound in a coil shape.
Abstract:
The invention relates to a winding tooth (3) for an electric machine with a tooth stem (4) and a tooth tip (5), which is arranged at one end of the tooth stem (4) with respect to a direction of extent (E) of the tooth stem (4) and which protrudes beyond the tooth stem (4) in a tooth tip direction (U) perpendicular to the direction of extent (E), wherein the tooth tip (5) is tapered at at least one end with respect to a transversal direction (Z), which runs perpendicular to the direction of extent (E) and perpendicular to the tooth tip direction (U), in which the tooth tip (5) protrudes.
Abstract:
The invention relates to an electronically commutated electric motor comprising a stator encompassing a rotor (20), the stator comprising a plurality of branches (A, B, C), each comprising at least one pair of coils (S1, S2; S3, S4; S5, S6), the coils of said pair of coils being adjacently disposed on the circumference of the stator and wound in opposite directions.
Abstract:
The invention relates to a device for retaining a machine component (3), in particular a stator, in a housing (2, 13) of an electric machine, wherein a pressure element (20) is provided in the housing (2, 13) in order to press the machine component (3) with a force against a stop (31).
Abstract:
An electrical machine (100) comprises a housing (110), a stator (200) arranged in the housing and a conical spring washer (300), which holds the stator (200) in its installed position by means of a predetermined axial spring force (FA). In this case, the conical spring washer (300) comprises an annular base body (310), which is attached to a housing inner wall (110) by means of an attachment device (330), as well as a number of spring structures (320) which extend from the annular base body (310) in the direction of the stator (200) and support the stator (200) axially.
Abstract:
The invention relates to an electric machine, comprising a stator (2), a rotor (3), a split cage (4), which separates a wet region (5) from a dry region (6), control electronics (9) and an interconnection element (7, 8), which produces an electrical contact between the stator (2) and the control electronics (9), wherein the rotor (3) is arranged in the wet region (5), wherein the interconnection element (7, 8) is surrounded at least partially by an insulating element (10), and wherein the insulating element (10) divides the dry region (6) into a first subregion (60), in which the stator (2) is arranged, and a second subregion (61), in which the control electronics (9) are arranged.
Abstract:
Known pole plates for electric machines are designed from sheet metal stacks or laminated stacks. The sheets are stamped out of a sheet metal strip and processed individually or as a combined stack of sheets. However, the stamping process requires a high weight of material. The aim of the invention is to drastically reduce said weight of material. The invention therefore proposes a pole plate or stator laminations that is or are constructed of several flat layers of metal (1). To achieve bundles of metal layers (1) that are packed in screw form, a metal strip (2) is wound around a support body (3), in particular a dome, said strip being formed into a screw (8) by edge winding rolls. The support body (3) is then removed leaving the metal layers (1) packed in screw form. One application of the invention is for engines with an air gap winding, specifically supercharger engines.
