Title:
MINING EXPLOSION-PROOF THREE-PHASE PERMANENT MAGNET SYNCHRONOUS DRUM
Document Type and Number:
WIPO Patent Application WO/2023/165249
Kind Code:
A1
Abstract:
The present invention relates to the technical field of permanent magnet synchronous drums, and particularly relates to a mining explosion-proof three-phase permanent magnet synchronous drum, comprising a stator assembly and an outer rotor, which is rotationally arranged on an outer peripheral surface of the stator assembly. The stator assembly comprises a stator core, and a bearing housing welding assembly and a bearing housing assembly, which are respectively arranged at two ends of the stator core, wherein wire slots are provided in an outer peripheral wall of the stator core, and the stator core is provided with air channels in an axial direction thereof; the bearing housing assembly is provided with a first vent, and the bearing housing welding assembly is provided with a second vent; and two ends of each air channel are in communication with the first vent and the second vent, respectively. When in use, the air intake amount at one end of the stator assembly is increased by omitting a spindle, such that the cooling of an apparatus is greatly improved, that is, the cooling efficiency is improved, thereby ensuring the cooling stability and reliability of the apparatus, and avoiding the problem of the cooling effect of an existing outer rotor drum being poor due to a central spindle of the outer rotor drum affecting the intake amount of cold air.
