Abstract
A rotor for an externally excited synchronous machine. The rotor includes rotor windings arranged on a rotor shaft, a balancing ring, and a rectifier electrically connected to the rotor windings. On the balancing ring, a rotary transformer rotor of a rotary transformer with a secondary coil is arranged. The rotary transformer rotor projects from the balancing ring in an axial direction.

A rotor for an externally excited synchronous machine, comprising:
- rotor windings arranged on a rotor shaft,
- a balancing ring,
- a rectifier electrically connected to the rotor windings,
- wherein on the balancing ring a rotary transformer rotor of a rotary transformer with a secondary coil is arranged, the rotary transformer rotor projects from the balancing ring in an axial direction;
- and
- wherein the rectifier is arranged radially within the balancing ring and supports itself on a radial step of the balancing ring or on an inner lateral surface of the balancing ring.
An externally excited synchronous machine, comprising an electrically energisable rotor, the rotor including:
- a rotor shaft including rotor windings arranged thereon,
- a balancing ring,
- a rectifier electrically connected to the rotor windings,
- a rotary transformer arranged on the balancing ring and including a rotary transformer rotor with a secondary coil arranged on the rotary transformer rotor, wherein the rotary transformer rotor projects from the balancing ring in an axial direction;
- a rotary transformer stator with a primary coil and a transformer core of a magnetic core material;
- and
- wherein the transformer core comprises an inner ring, an outer ring and a stator bridge connecting the inner ring and the outer ring in each case on a face-end, wherein the primary coil is arranged in a recess on the inner ring, and wherein between the inner ring and the outer ring an annular recess is arranged.
