摘要： Although in a conventional permanent magnet type synchronous motor, cogging torque is reduced by displacing permanent magnets of a rotor in a circumferential direction or displacing a stator core in a circumferential direction, since the skew so produced reduces the output of the motor and moreover the winding work of windings cannot be automated to make the resulting motor highly expensive, split cores are provided which solves those problems and enables the winding work of windings to be automated so as to obtain an inexpensive and high-output motor.There are provided a plurality of split cores (100) made up of laminated iron cores each having formed thereon a tooth (6), and a yoke (5) and a pole piece (9) which are made to connect to the tooth (6) at both ends thereof, and arranged and connected together into an annular shape to make up a stator, characterized in that both ends of the yokes (5) and both ends of the pole pieces (9) are displaced in one circumferential direction by laminated iron core from a top laminated layer to a bottom laminated layer of the iron cores of the split cores.
