Dovetail Rotor Construction For Permanent-Magnet Motors
Author and Affiliation:
Kintz, Lawrence J., Jr.(Sundstrand Corp.)
Puskas, William J.(Sundstrand Corp.)
Abstract: New way of mounting magnets in permanent-magnet, electronically commutated, brushless dc motors. Magnets wedge shaped, tapering toward center of rotor. Oppositely tapered pole pieces, electron-beam welded to rotor hub, retain magnets against centrifugal force generated by spinning rotor. To avoid excessively long electron-beam welds, pole pieces assembled in segments rather than single long bars.
