Abstract
A method for bonding a plurality of Nd—Fe—B permanent magnets includes a step of curing the layer of insulating adhesive at an initial temperature of between 20° C. and 250° C. and between 0.1 hr and 24 hr prior to the step of sandwiching. A predetermined clamping pressure of between 0.1 MPa and 10 MPa is then applied to the Nd—Fe—B permanent magnets. The stacked Nd—Fe—B permanent magnet is cured at a predetermined temperature of between 150° C. and 350° C. and between 0.1 hr and 12 hr. A clamping tool apparatus includes at least one of three intermediate guides disposed on the lower plate, in the chamber, spaced from the magnet positioning members, and extends to a proximal end defining a second predetermined distance with the second predetermined distance being less than the first predetermined distance of the magnet positioning members. The upper plate defines a plurality of apertures for receiving the magnet positioning members and the intermediate guides.
