摘要： A reluctance-type motor comprises, for each of its rotor and stator, a core that has a cylindrical ring and a plurality of salient poles protruding from the ring in a radial direction of the ring. Each pole has a bottom width and a top width in a circumferential direction of the core at its bottom and at its top, respectively. The bottom width is sized to be larger than the top width, and the ring has a width sized to be larger than a half of the top width of the pole. The pole may be shaped to have a round corner at the bottom or in a trapezoid in which the bottom width is larger than the top width. The core may have a plurality of thin magnetic plates stacked in an axial direction of the core, each plate has a plurality slits in each protrusion which forms the pole, and each plate has a thickness which is less than 5 times of a maximum width of each slit.
