A permanent magnet type AC low-velocity synchronous motor comprises a stator having a first small-toothed unit plate which is formed on an inner surface thereof with radial teeth, a unit AC coil, and a second small-toothed unit plate which is formed on an inner surface thereof with radial teeth, the first small-toothed unit plate, the unit AC coil, the second small-toothed unit plate defining one phase and being sequentially inserted into a case to be coupled one with another; and a rotor having a first pair of core plates which are mounted around a rotating shaft, have the same length as the first and second small-toothed unit plates and are formed on outer surfaces thereof with radial teeth such that the radial teeth of the first pair of core plates correspond to the radial teeth of the first and second small-toothed unit plates, respectively, and a first permanent magnet which is positioned between the first pair of core plates thereby to correspond to the unit AC coil and has the same length as the unit AC coil, the first pair of core plates and the first permanent magnet defining another phase, the rotor further having a second pair of core plates and a second permanent magnet which are disposed adjacent to the first pair of core plates and the first permanent magnet so as to afford starting power, the first and second pair of core plates having a phase difference therebetween. |
