Patent ID: 8262971

Claim:
A method for centering and retaining a molded end coil in a magnet former which includes a circumferentially extending oversleeve for retaining the end coil in position, a radially outer surface of the end coil being of lesser diameter than a radially inner surface of the oversleeve, said method comprising the steps of: (a) centering the end coil on the former by passing a spigot through a bore of the end coil and into an end of a bore of the magnet former to locate the molded end coil within the oversleeve, leaving a gap between the radially outer surface of the end coil and the radially inner surface of the oversleeve; (b) retaining the end coil in position against an axially adjacent surface of the former by applying an axial force to the end coil in the direction of the former; (c) filling the gap with a hardening material along at least part of its axial length; (d) causing or allowing the hardening material to harden, thereby to securely and accurately retain the end coil onto the former; and (e) removing the spigot.
