Title:
永久磁石をクランプ及びロックし、傾斜した集中磁束磁石を用いて回転電気機械内の冷却を改善する装置及び方法
Document Type and Number:
Japanese Patent JP2010534459
Kind Code:
A
Abstract:
Permanent magnets are mounted within an electrical machine in a pitched saw-tooth pattern around the rotor shaft. This focused flux configuration provides for improved magnet mounting strength without resort to bonding or taping; provides improved rotor and stator cooling by access to the axial generator air flow; and provides for a simpler and more easily manufactured design. A laminated version of this basic structure provides for reduced surface losses and self-heating.
