A configuration is such that the lead terminal has a lead protruding portion protruding from a contact with the regulator holder, and the IC regulator is positioned by the lead protruding portion being fitted into the lead opposing portion of the regulator holder.

A system for transferring current between a rotating element and a fixed element, comprising—a support in the general shape of a sheet (10) comprising a conductive portion (11) electrically connected to the fixed element, —a brush holder (20) mounted on the support (10) and supporting a brush (30) that is pushed into contact against the rotating element, —electrical connection means (42) for connecting the conductive portion (11) of the support to a cable (40) that is joined to the brush (30), wherein a resistive element (12) is situated between the brush (30) and the conductive portion (11) of the support (10) and prevents current from flowing directly between the conductive portion and the brush.

An electric motor, in particular a separately excited synchronous motor, has a rotor shaft with at least one slip ring and at least one electrically conductive contact element, in particular a carbon brush, which bears against the slip ring and is accommodated in a channel-like guide formed in a housing and extending radially with respect to the rotor shaft and which carbon brush is radially tensioned against the slip ring by means of a spring element, wherein a roller is provided which is tensioned laterally against the contact element via a further spring element and via which the contact element is tensioned against a wall of the guide.

The present disclosure describes an electrical machine. The Electrical machine includes a stator, a rotor, a winding fitted to the rotor, and an apparatus for supplying electrical energy to the winding. The apparatus includes a slip ring and a brush assembly including a brush holder and a brush. The slip ring and the brush assembly are arranged in a housing. An annular gap is disposed between the slip ring and the housing. The housing is fluidically substantially sealed in relation to an exterior, and a flow path of air is routed through the housing in a closed arrangement. The housing includes a housing part fluidically connected to the annular gap via a first flow opening and a second flow opening. A flow section of the flow path is routed through the housing part, and leads from the first flow opening to the second flow opening.

An alternator includes a housing and a rotary shaft. The alternator includes one or more brushes supported by the housing. The alternator includes a slip ring assembly coupled to the rotary shaft for rotating with the rotary shaft. The slip ring assembly includes one or more slip rings. The one or more slip rings include a body portion defining an outer surface. The one or more slip rings also include an oxide layer disposed on the outer surface of the body portion. The oxide layer is non-uniform. The oxide layer is formed on account of a thermal oxidation process of the one or more slip rings during an operation of the alternator. Further, the thermal oxidation process for formation of the oxide layer initiates when an operating temperature of one or more components of the alternator lies within a predetermined temperature threshold range.

A brush holder for holding at least two brushes for a sliding contact arrangement, comprising an intermediate element and two contact elements for electrically contacting at least one of the brushes, the contact elements being arranged on two opposite sides of the intermediate element and the intermediate element having a receptacle extending through the opposite sides for a rotating shaft.

A slip ring assembly includes a housing having a stator that rotatably supports a rotor. The rotor includes conductive disks that are electrically connected to respective conductors extending through a rotor shaft. The stator includes brushes that slidably and electrically engage the conductive disks. The one or more brushes are electrically connected to stator conductors extending at least partially through the stator. Electrical pathways are defined and extend from the stator conductors, the brushes, the conductive disks, and the respective conductors in the shaft. A smart board is connected to the stator and includes electronic components configured to monitor operation of the slip ring assembly and provide signals to an external source. The smart board is electrically connected to, and powered by, electrical power that is present and available on the stator conductors.

An electric machine for a vehicle, in particular for a utility vehicle, includes a rotor mounted rotatably on a shaft and a stator surrounding the rotor, at least one device of the electric machine located in at least one pressure chamber which is subjected at least intermittently to an overpressure which is elevated with respect to the ambient pressure. The over pressure in at least one pressure chamber protects against ingress of water.

The present invention provides a motor generator, and the motor generator comprises a permeability structure, a bearing, a hollow rotating shaft, a ringed clip and a rotatable guiding structure. The permeability structure comprises a primary permeability unit and a secondary permeability unit wherein the second permeability unit is stacked with the first permeability unit along an axial air-gap to form a symmetrical structure having a hollow shaft. The bearing is disposed inside the hollow shaft of the permeability structure. The hollow rotating shaft is passed through the hollow shaft of the permeability structure and disposed at another side of the bearing with respect to the permeability structure. The ringed clip is used for fixing the bearing and the hollow rotating shaft. The rotatable guiding structure is disposed inside the hollow rotating shaft for providing power source and transmitting signals.

A controller integrated rotating electrical machine is designed to minimize adverse thermal effects on a control device. The controller device includes switching modules, a control circuit, and a casing. The switching modules are disposed inside the casing at a distance from a rear housing. The control circuit is disposed in the casing and located in front of the switching modules at a distance from the rear housing and the switching modules. In other words, the control circuit is arranged away from the switching modules which are a heat source when operating, thereby eliminating adverse thermal effects on the control circuit.
