Abstract
A built-in permanent magnet motor structure combining W-type installation and a squirrel-cage type adopts built-in type 'W'-shaped magnetic steels distributed evenly. A magnetic-insulation magnetic bridge is disposed at each corner connecting position of the 'W'-shaped magnetic steels, the magnetic steels are integrally evenly distributed, a plurality of winding wires are evenly arranged on the outer circles of the magnetic steels and are evenly distributed along the outer circumferences. By adopting technique of combining W-type installation and a squirrel-cage type, the structure greatly reduces magnetic leakage coefficient, requires no magnetic insulation on a rotary shaft, has easily-controlled pole arc coefficient, high mechanical strength of a rotor lamination punching machine and simple technique, a permanent magnet is difficult to deform after installation, and magnetic flow within same polar distance is provided by connecting two adjacent magnetic poles in parallel, thereby obtaining more magnetic flux.
