Document Type and Number:
Japanese Patent JP2018129893
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an outer rotor type motor and a flying device having high waterproof and dustproof performance.SOLUTION: The outer rotor type motor in which a rotor rotates around a stator includes a stationary support for fixedly supporting the stator in a non-rotatable manner while rotatably supporting a rotation body including a rotor via a bearing. Then, between an open-end side of a cup-shaped rotation body and the fixed support, a bending labyrinth clearance is formed. A water repellent coating film is formed on a portion to be a facing surface forming the labyrinth clearance. A propeller is attached to the rotational output shaft of this outer rotor type motor to make it a driving source of a compact flying device.SELECTED DRAWING: Figure 5
