Abstract
An electric coil device includes a winding support which is made of an elongated hollow tube that has the shape of a ring such that a higher-order loop of the winding device is formed entirely by the annular shape of the winding support, and a winding which is made of a superconductive conductor and is attached to the winding support. The superconductive conductor is wound in a helical manner about the hollow tube in a plurality of individual windings such that at least one higher-order winding of the entire helix is produced by the annular shape of the winding support. The interior of the hollow tube is designed as a coolant channel for circulating a fluid coolant. A rotor for an electric machine includes at least one such coil device.
