摘要：
Split cores comprising laminated iron cores each having formed thereon a tooth, and a yoke and a pole piece which are connected to the tooth at both ends thereof, and arranged and connected together into an annular shape to make a stator. Both ends of the yokes and both ends of the pole pieces are displaced in one circumferential direction by laminated iron core from a top laminated layer of the iron cores of the split cores to a bottom laminated layer of the iron cores or split cores.
