| Zusammenfassung: | PROBLEM TO BE SOLVED: To protect enamel coating of an electric wire in a rotor coil end. SOLUTION: In the rotor coil end, a lubrication layer is installed between a coil-pressing rod 4 and an insulating sheet 5 by using a fluororesin tape 9 or the like, and a sliding surface is formed in a part except a field winding 3. Thereby sine the coil-pressing rod 4 slides easily between the lubrication layers, the insulating coating of the wire constituting the field winding 3 can be protected, even if centrifugal force is increased. |
