▎ 摘　　要

NOVELTY - Polarization heat-dissipating unit permanent magnet motor comprises motor housing (1), magnetic conductor, motor shaft (3), permanent magnet (4) and rotor (5). The motor shaft is arranged in motor housing. The both ends of motor shaft extends to outside of motor housing. The rotor is installed on outer surface of motor shaft. The stator (6) is fixed on inner wall of motor housing. The rotor is arranged opposite to stator, and permanent magnet is installed on motor shaft. The magnetizer is installed on one side of motor housing, and permanent magnet and rotor are both installed in inner cavity of motor housing. The permanent magnet is arranged between permeable magnet and rotor. The motor casing is provided with cooling water inlet (7) and cooling water outlet (8). The inner wall of motor casing is provided with cooling water channel. USE - Polarization heat-dissipating unit permanent magnet motor. ADVANTAGE - The polarization heat-dissipating unit permanent magnet motor has weak magnetic permeability and strong thermal conductivity, and derives heat generated when motor stator is running. DESCRIPTION OF DRAWING(S) - The drawing shows schematic view of polarization heat-dissipating unit permanent magnet motor.
