摘要： A slip ring unit for an electrically excited rotor of a rotary dynamo-electric machine includes an electrical terminal which protrudes axially from an end face of the slip ring unit and having a contact point and a circumferential slip contact surface electrically connected to the electrical terminal. Disposed adjacent to the slip contact surface is an insulation element, with end plates axially retaining the circumferential slip contact surface and the insulation element. An electrically insulated support element is arranged on an end face of the slip ring unit and has a cross section which substantially matches a cross section of the slip ring unit. The support element axially surrounds the electrical terminal and radially supports the electrical terminal.

摘要： An electric motor having an armature which includes a coating of thermally conductive plastic applied in a conventional injection molding process. The armature also includes a fan which is integrally formed from the thermally conductive plastic applied to the armature. This completely eliminates the need to apply one or more coatings of a trickle resin to the armature. It also eliminates the need to separately form and secure a fan by a suitable adhesive to the armature, which together significantly simplifies the manufacturing and cost of the armature. The plastic coating also better fills the spaces between the magnet wires, thus promoting even more efficient cooling and better holding of the magnet wires stationary relative to one another. The thermally conductive plastic coating may be mixed with other suitable materials to provide a density approximately equal to the magnet wires. This eliminates the need to balance the armature after the injection molding step.
