Document Type and Number:
WIPO Patent Application WO/2023/095964
Kind Code:
A1
Abstract:
The present invention provides a technology in which a cooling structure for efficient cooling of a permanent magnet motor to be employed in a turbo blower is presented, so that the motor efficiency of a turbo blower permanent magnet motor can be increased. A plurality of outside air inlets provided in the motor casing of the turbo blower are formed at a position between a closing ring and one side of a stator and close to the closing ring, have a circular hole shape with the same diameter, and are formed at equal intervals in the same concentric circle around the outer circumferential surface of the motor casing.
