Document Type and Number:
WIPO Patent Application WO/2023/237106
Kind Code:
A1
Abstract:
Embodiments of the present invention provide a fully-sealed brushless motor for dry and wet applications, a protective structure for a motor, and an installation method. The motor comprises a motor casing body, a motor rotor, a stator core, a moving impeller, an air guide enclosure, a circuit board, and a circuit board end cover; the motor casing body comprises an upper aluminum casing body and a lower aluminum casing body connected together in a sealed manner; the motor rotor is arranged in a space enclosed by the upper aluminum casing body and the lower aluminum casing body, and the motor rotor transmits heat to the upper aluminum casing body and/or the lower aluminum casing body by means of the stator core to undergo heat dissipation; a rotating shaft of the motor rotor sealingly fits with a bearing and extends out from the lower aluminum casing body, the moving impeller is installed at the shaft head of the rotating shaft; the air guide enclosure is installed on the lower aluminum casing body at an outer side of the moving impeller; a gas flow discharged by the moving impeller is blown towards the motor casing body by means of the air guide enclosure, and the heat of the motor casing body is simultaneously taken away; the circuit board is arranged in a space enclosed by the sealingly connected circuit board end cover and upper aluminum casing body, and a lead of the circuit board passes, in a sealed manner, through a lead outlet hole formed in the circuit board end cover and extends outward.
