BRUSHLESS ALTERNATOR WITH STATIONARY SHAFT

摘要

Disclosed herein is a rotor assembly for an electric machine including a stationary shaft (12b), a first bearing (34), a second bearing (34), a first pole segment (18b), a second pole segment (2Ob), a first internal fan (38), and a second internal fan (38). The first bearing (34) is positioned at a first end of the shaft (12b). The second bearing (34) is positioned at a second end of the shaft (34). The first pole segment (18b) is supported by the first bearing (34) and is rotatable about the shaft (12b). The second pole segment (20b) is supported by the second bearing (34) and is rotatable about the shaft (12b). The first internal fan (38) is attached to the first pole segment (18b). And, the second internal fan (38) is attached to the second pole segment (20b).
