Title:
MOTOR COOLING STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2020/122077
Kind Code:
A1
Abstract:
[Problem] To provide a motor cooling structure capable of improving cooling efficiency when cooling a motor that has reached a high temperature. [Solution] In the motor cooling structure equipped with a motor disposed on a board and a propeller rotated by driving of the motor, the propeller is formed by a thermally conductive member and the motor is provided with: a stator having coils disposed therein and formed by a thermally conductive member for transferring the heat generated from the coils to the board; and a rotor having the propeller connected thereto, combined with the stator, having magnets disposed therein to generate a magnetic field between the coils disposed in the stator and the magnets, and formed by a thermally conductive member for transferring the heat generated from the magnets to the propeller. The heat transferred from the rotor to the propeller by the rotation of the propeller is dissipated, and the heat transferred from the stator to the board is dissipated to an air flow generated by the rotation of the propeller.
