A rotor () for an electric machine () with a central rotor axis (A) is specified. The rotor comprises&#x2014;at least one superconducting coil element () with a local winding axis (a), and&#x2014;at least one winding carrier () into which the coil element () is embedded, &#x2014;wherein a cohesive connection is formed between the winding carrier () and the coil element (), &#x2014;wherein the cohesive connection is provided on a connecting surface () which forms only a first partial region of the entire contact surface () between coil element () and winding carrier (). Also specified are a machine with a rotor () of said type and a production method for a rotor () of said type.

Rotor with winding carrier and coil element embedded therein

Various embodiments include a rotor for an electric machine comprising: an electric coil arrangement; and a winding carrier mechanically carrying the coil arrangement and at least partially enclosing the coil arrangement on a radially outer side of the coil arrangement. The rotor includes an inner cavity for circulating a fluid coolant such that the coil arrangement comes into contact with the liquid coolant on its radially inner side as the rotor rotates.
