摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.
