Methods and systems are provided for a winch including a motor and a contactor assembly positioned within a same housing. In one example, the contactor assembly is coupled to the motor and includes two or more coils spaced apart from one another within a contactor housing of the contactor assembly and a brush assembly including a plurality of brushes surrounding a rotational axis of the motor and arranged axially to the motor armature.

A motor includes a housing, a back cover, a brush card, a brush, and a connector member. The back cover includes a first rear wall portion and a first peripheral wall portion. The first peripheral wall portion includes a through-hole and a cut-out. The through-hole vertically penetrates through the first peripheral wall portion at or near a lower end portion of the first peripheral wall portion. The cut-out is disposed farther on an upper side than the through-hole. The connector member is fitted into the cut-out. An outer surface of the connector member is provided with a flow path groove that extends in both peripheral and axial directions. The motor includes a flow path surface on an inner surface of the back cover. The flow path surface continues from a portion that opposes the flow path groove on a lower side of the flow path groove to the through-hole.

A DC motor includes: a brush configured to be connectable with the commutator; a first terminal attached to the brush; a second terminal disposed at a position away from the first terminal, the second terminal being configured to be connectable with an external terminal; a bracket to which the first terminal and the second terminal are attached; and a positive temperature coefficient (PTC) thermistor disposed between the first terminal and the second terminal, the PTC thermistor including a first electrode bonded to the first terminal and a second electrode bonded to the second terminal, wherein the PTC thermistor is a surface-mount type thermistor in which the first electrode and the second electrode are exposed on one surface side and wherein, on the one surface side of the PTC thermistor, the first electrode faces the first terminal and the second electrode faces the second terminal.

An end cap assembly for an electric motor has an end cap body and at least two motor terminals. The end cap body has at least two holding structures for respectively holding the at least two motor terminals, each holding structure having at least one holder and a through slot. Each motor terminal has a base portion, a terminal portion and at least one mounting portion. The at least one mounting portion is mounted to the at least one holder of a corresponding holding structure. The terminal portion is inserted in the through slot to electrically connect to a male terminal of an external power supply plug. The terminal portion and the at least one mounting portion integrally extend from the base portion.

An induction motor or generator assembly for converting either of an electrical input or rotating work input to a mechanical/rotating work or electrical output. An outer annular arrayed component is rotatable in a first direction and includes a plurality of magnets arranged in a circumferentially extending and inwardly facing fashion according to a first perimeter array, the outer component further incorporating a rotating shaft projecting from a central location. An inner concentrically arrayed and reverse rotating component exhibits a plurality of outwardly facing and circumferentially spaced array of coil-subassemblies opposing the magnetic elements, such that a gap separates the coil-subassemblies from the magnets. The coil sub-assemblies each include a plurality of concentrically arrayed coils configured within a platform support of the inner component. A fixed commutator has a plurality of annular extending and individually insulated segments, a similar plurality of outer rotating brushes in continuous contact with the commutator segments.

Methods and systems are provided for a winch including a motor and a contactor assembly coupled around the motor. In one example, the contactor assembly includes an outer casing with a planar, inner end wall. Additionally, the contactor assembly includes a plurality of angled inner surfaces disposed adjacent to the cylindrical housing of the motor.

A motor includes a cylindrical rotor housing that contains a rotor, a brush holder mounted to an opening of the rotor housing, an end plate, having an electrically conductive part, which holds the brush holder in between the end plate and the rotor housing, and a grounding mechanism that realizes a ground connection to both a part of wiring led to a brush, provided in the brush holder, and the end plate. The grounding mechanism is provided in a region where the brush holder faces the end plate.

A drive system with a plurality of electromotive drives, specifically servo drives, the electronics of which are interconnected or connectable by way of a hybrid bridge. The hybrid bridge has a hybrid cable and a plug-in connector on the cable termination side for power conduction and data transmission. There is provided a drive of this type and a hybrid bridge of this type.

Brush holder support plate (1) for an electric engine comprises a central through-hole (2) for the engine manifold and guide elements (10) for receiving brush holders (20) in sliding connection on the plate. The plate allows the brush holder to be mounted on the plate, engaging same in the direction running from the edge (1e) of the plate towards the central through-hole (2). The plate comprises a non-return stop (11) for each brush holder (20) after the latter has been mounted in sliding connection on the plate, the stop being elastically retractable. The brush holders (20) have a base shaped so as to be received in sliding connection in the guide elements (10) of the plate (1). They have a recess in the base of same suitable for being engaged by the corresponding non-return stop (11) of the plate (1).
