Abstract
Magnet assemblies including a case, a plurality of elongate diametrically magnetized magnets within the case, and damping liquid within the case, and methods of assembling such magnet assemblies.
Claims22
A method of assembling a magnet assembly, comprising:
- positioning a plurality of elongate diametrically magnetized magnets within a first case member including a first end wall and a first side wall portion;
- securing a second case member, including a second end wall and a second side wall portion, to the first case member to form a case defining a central axis and in which the elongate diametrically magnetized magnets are located, by welding the first side wall portion to the second side wall portion, wherein one of the first and second end walls includes a port;
- introducing damping liquid into the case by way of the port;
- and
- sealing the port after the damping liquid into the case has been introduced into the case by way of the port.
