FAN ARRANGEMENT FOR AN ELECTRICAL MACHINE

摘要

The invention relates to a fan arrangement for an electrical machine, comprising a fan (10) that rotates about an axis, with air flowing into the fan (10) in the axial direction and flowing out of the fan (10) in the radial direction. The arrangement further comprises an end shield (12) and a magnet wheel (14). A flow channel (16) is at least partially defined by the end shield (12) and the magnet wheel (14) and the cross-section of flow of the flow channel (16) is substantially constant in the radial direction.
