Abstract
Official abstract text for this publication.
A fixation system that is structured to secure one or more permanent magnets to a rotor core. The fixation system may include one or more retention wedges that exert an interference or press fit against the permanent magnets to secure the permanent magnets to the rotor core. At least a portion of the retention wedges may be secured within axially extending channels in the rotor core. Additionally, the permanent magnets may be separated from each other by eddy current shields, which may also be retained in position by the retention wedges. The fixation system may also include a magnet pressure or fixation sleeve that exerts a radially inwardly directed force against the magnets and is free from direct contact with the retention wedges. According to certain embodiments, the magnet pressure or fixation sleeve may be shrink fitted onto at least a portion of the rotor core and/or the permanent magnets.
First claim
Opening claim text (preview).
1 . An apparatus comprising: at least one pair of retention wedges positioned adjacent to opposing sides of one or more magnets, the at least one pair of retention wedges secured to a rotor core, the at least one pair of retention wedges exerting a force against opposing sides of the one or more magnets to retain a position of the one or more magnets about the rotor core; and a magnet pressure sleeve positioned radially outwardly of, and against, the one or more magnets and separated from the…
