Document Type and Number:
WIPO Patent Application WO/2021/212323
Kind Code:
A1
Abstract:
A motor (100), a power device (4000) and an unmanned aerial vehicle (1000). The motor (100) comprises a base (10), a stator (30) and a rotor (20). The rotor (20) covers the base (10) and forms an accommodating space (15), and the stator (30) is fixedly connected to the base (10) and is located in the accommodating space (15). The rotor (20) comprises a first cover (21) and a second cover (22). The first cover (21) comprises a top wall (211) and a side wall (212), the side wall (212) is connected to an outer edge of the top wall (211), the side wall (212) is provided with a through hole (213), and the through hole (213) is in communication with the accommodating space (15) and the outside. The second cover (22) comprises a main body (221) and a centrifugal member (222), the main body (221) is connected to the top wall (211), the centrifugal member (222) is connected to the main body (221), and airflow passing through the through hole (213) is generated when the centrifugal member (222) rotates, so that the accommodating space (15) exchanges gas with the outside.
