A method for putting an SSM rotor, having the following steps: arranging the SSM rotor to be potted having upright alignment in a potting mold; introducing a first casting compound from below into the casting mold until a certain pre-fill level is reached, at which the first casting compound extends at least up to the lower end face of the rotor winding; introducing a second potting compound from above into the potting mold, wherein the second potting compound is poured onto the rotor winding and is drawn into the rotor winding; further introducing of the first potting compound from below into the potting mold until a certain final fill level is reached; and curing of the potting compounds.

Method for potting an SSM rotor and SSM rotor having hybrid rotor potting

A method for producing a wire coil. Multiple windings of a ply of the wire coil including an insulated wire are wound onto a coil core of the wire core starting from a first winding up to a last winding. The last winding is hooked in an electrically insulating deflection hook of the wire coil which is fixed with respect to the coil core and the wire is deflected by the deflection hook.

Method for producing a wire coil, corresponding wire coil, and method for producing an electrical machine

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.

Electric motor, in particular a separately excited synchronous motor

An electric machine, including a stator and a rotor shaft having a cooling device, which shaft carries at least one slip ring, which has a lateral surface, which electrically contacts a contact element fixed on the stator, and which is at least partially accommodated in a recess of the rotor shaft, wherein an extension section of the slip ring, which is at least partially accommodated in the recess, extends beyond the lateral surface in one or both axial directions of the rotor shaft.

Electric Machine

Vehicle having a high-voltage battery which has a housing, wherein the housing has a housing floor which is essentially parallel to an underlying surface on which the vehicle is standing or travelling, a housing cover which is arranged spaced apart from the housing floor, housing walls via which the housing floor is connected to the housing cover. The housing has at least one housing structure plate which has a plane of maximum size which is perpendicular with respect to the housing floor and with respect to the housing cover, and an underside which faces the housing floor or is connected thereto, and an upper side which faces the housing cover or is connected thereto. In an interior space of the housing structure plate at least two parallel cooling ducts are provided, through which coolant or a cooling agent flows, and on a first side and a second side, lying opposite the first side, of the housing structure plate at least one electrical storage cell is respectively arranged, in particular a multiplicity of electrical storage cells are respectively arranged, wherein the storage cells each have a positive and a negative connecting pole. At least one connecting pole or both connecting poles of the storage cells is/are connected to the first and/or second side of the housing structure plate in a thermally conductive and electrically insulated fashion.

Vehicle having a high-voltage battery

Spatially mutually close pole components are offset with respect to one another such that their influences on a given harmonic of the vibrations occurring during operation cancel one another as much as possible. The present invention therefore suggests concepts and makes dimensioning proposals by means of which certain harmonic orders of the operating noise can be reduced.
