A permanent magnet laminated motor, comprising: 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 the 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) correspondingly. A same 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) through a plurality of installation screw rods (74, 75). The permanent magnet laminated motor has the advantages that the weight is mitigated, the volume is reduced, and the self-cooling effect is good. Moreover, the utilization rate of the silicon steel sheets is increased, the consumption of structural materials is effectively minimized, and specific power of the motor is far greater than a common cartridge type motor and a disc type motor. |
