Title:
BRUSHLESS DIRECT-CURRENT ELECTRIC MOTOR
Document Type and Number:
WIPO Patent Application WO/2024/061103
Kind Code:
A1
Abstract:
The present invention relates to the technical field of electric motors, and particularly relates to a brushless direct-current electric motor. The brushless direct-current electric motor comprises a brushless direct-current electric motor body (10), and a heat dissipation cover (20) arranged corresponding to a heat dissipation air outlet of the brushless direct-current electric motor body (10), wherein a plurality of air guide plates (21) are arranged at the end portion of the heat dissipation cover (20) that extends outwards in a radial direction; the air guide plates (21) are sequentially arranged at intervals in a circumferential direction; the air guide plates (21) are offset by an acute angle in the same direction in the radial direction of the heat dissipation cover; and an air guide port is formed by means of two adjacent air guide plates (21). In the present invention, the plurality of air guide plates are arranged at the end portion of the heat dissipation cover that extends outwards in the radial direction, the air guide plates are sequentially arranged at intervals in the circumferential direction and are offset by an acute angle in the same direction in the radial direction of the heat dissipation cover, and one air guide port is formed by means of two adjacent air guide plates, thereby greatly improving the heat dissipation efficiency, prolonging the service life of the brushless direct-current electric motor and improving the performance thereof.
