A permanent magnet laminated motor includes two end plates (15,16) arranged in parallel; a rotating shaft (1) rotatably arranged between the two end plates (15,16); n+1 rotor units (11, 12, 13, 14) and n spacer rings (8, 9, 10) alternately fixedly sleeved on outer rims of the rotating shaft (1) and axially compacted; two magnetic conductive rings (6, 7) tightly sleeved at the outer rim of the rotating shaft (1) and tightly attached to the outer side of the outermost two rotor units (11, 14); and n stator units (37, 38, 39) respectively sleeved at the outer rims of the spacer rings (8, 9, 10). An axial air gap (40) is provided between each stator unit (37, 38, 39) and the adjacent rotor unit (11, 12, 13, 14), and the n stator units (37, 38, 39) are axially fixedly connected to the two end plates (15, 16) by installation screw rods (74, 75). |
