Document Type and Number:
WIPO Patent Application WO/2023/236871
Kind Code:
A1
Abstract:
The present application relates to a motor and a flying device. The motor comprises a stator, a rotor, and a heat dissipation apparatus. The rotor is sleeved outside the stator, and the rotor is provided with an accommodating space for accommodating the stator; the rotor has a first end and a second end that are opposite to each other, and the accommodating space forms a first opening at the first end. The heat dissipation apparatus is disposed in the accommodating space and located on the side of the stator close to the first opening; the heat dissipation apparatus comprises a mounting member, a first fan, and a second fan; the mounting member is arranged outside the first fan in a surrounding mode, the first fan is connected to the rotor by means of the mounting member, the second fan penetrates through the first fan and is connected to the first fan, and the flow directions of airflows guided by the first fan and the second fan during rotation are the same. The first fan and the second fan of the motor respectively perform heat dissipation on different regions in the motor, thereby improving the heat dissipation efficiency of the motor.
