Title:
MAGNETIC-GEARED ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/070366
Kind Code:
A1
Abstract:
A magnetic-geared electric machine according to the present invention comprises: a stator; a pole piece rotor that includes a pole piece which is disposed further inward in the radial direction than the stator and a pole piece coupling part which is coupled to an end part of the pole piece on one side in the axial direction; a magnet rotor that is disposed further inward in the radial direction than the pole piece; a housing that accommodates the stator, the pole piece rotor, and the magnet rotor; a first bearing that is coupled to the housing and the pole piece coupling part; and a fan that is for sending cooling air to the first bearing and that causes the cooling air to flow to said one side from the other side in the axial direction in an outer air gap, which is formed between the stator and the pole piece, and in an inner air gap, which is formed between the pole piece and the magnet rotor. At least part of the first bearing is positioned further outward in the radial direction than the inner circumferential surface of the pole piece and further inward in the radial direction than the stator.
