Coil for producing magnetic field, e.g. for motor or generator, has reinforcement insert enclosing superconducting winding and enclosed in plastics

摘要

The coil has a superconducting winding (12) encapsulated in plastics. One winding end (19) allows connection of an electrical wire (15). The connection comprises an electrical connection piece (30) with a foot region (31) which is connected flat against the winding end and with a head region (32) for connecting the wire. The foot region is partially covered in the radial direction by a reinforcement insert (14) which encloses the winding and is encapsulated in the plastics.
