ADHESIVELY BONDED CYLINDRICAL MAGNETS COMPRISING ANNULAR COILS, AND METHOD OF MANUFACTURE THEREOF

摘要

In a solenoid magnet assembly, and a method for manufacture thereof, the magnet assembly includes a number of concentrically aligned coils, each including a winding impregnated with a resin. Each coil is mechanically restrained so as to hold the coils in fixed relative positions relative to each other when forming the magnet assembly. The mechanical restraint can be formed by annular support sections bonded to the respective coils, lugs bonded to the respective coils, or by lugs that are at least partially embedded in a crust formed on a radially outer surface of the respective windings.

1. A solenoidal magnet assembly comprising:
a plurality of concentrically aligned coils, each comprising a winding impregnated with a resin; each coil being adhesively bonded by a radially outer surface of the resin to a corresponding annular support section; a mechanical restraint acting on the annular support sections, that holds the annular support sections in fixed relative positions to form the magnet assembly; and spacers positioned between the annular support sections, wherein axial spacing between coils is defined by the axial length of the annular support sections and of the intervening spacers.
