A core has a plurality of plate-shape core pieces with a magnetic pole tooth and having connecting portions formed at one end and having a first circular arc end surface and having at the other end a second end surface which can mate with the first end surface of an adjoining core piece. The core pieces are arranged in the shape of a strip through the end surfaces to form a first core member and a second core member. The core members are stacked so that the ends of adjoining core pieces in the stacking direction overlap and such that adjoining connecting portions can freely rotate through connecting means to form a ring with the magnetic pole teeth on the inside. A cutout is formed in the corner of the outer side of the core in the second end surface of each core piece.

The magnetic performance, rigidity and mechanical precision of an iron core assembly can be improved. A plurality of plate-shaped core segments are disposed in succession to form a plurality of first and second core members respectively. Edge portions of adjacent core segments of the first and second core members are coupled with each other. The first and second core members are alternately laminated one over another in such a manner that first inter-segment positions each defined between adjacent two first core segments of the first core member are offset from second inter-segment positions each defined between adjacent two second core segments of the second core member in a longitudinal direction of the first and second core members, with those edge portions of the respective first and second core segments which adjoin each other in a laminating direction in which the first and second core members are laminated being overlapped each other. The core segments of the first and second core members are rotated relative to each other through the coupling means so as to form an enclosed or ring-like configuration.

An object of the present invention is to provide a low cost, high performance, thin structure rotary motor for driving medium used in magnetic disk drive unit, optical disk drive unit or the like, in order to improve the productivity of terminating processing and the reliability of the coils. Magnetic materials which are divided to a plurality of blocks or divided corresponding to respective magnetic pole teeth are connected by means of thin portions. The respective magnetic pole teeth are wound continuously with wire without cutting the wire at the positions in which the thin portions are connected. When a stator is assembled, a plurality of blocks or magnetic pole teeth are disposed on a substrate by separating or bending the thin portions.

A deflection yoke includes a hollow funnel-shaped tapered piece, a first set of winding hooks provided on a small-aperture portion of the tapered piece, a second set of winding hooks provided on a large-aperture portion of the tapered piece, and a deflection coil including first through n-th winding bundles. The first winding bundle includes a bundle of conductor wound onto a center winding hook at the center of the first set of winding hooks and onto the second winding hooks. The second winding bundle includes a bundle of conductor wound onto the center winding hook, the winding hooks adjacent thereto on either side, and onto the second winding hooks. The third and subsequent winding bundles include bundles of conductors wound onto the center winding hook, a plurality of winding hooks adjacent thereto on either side, and onto the second winding hooks. The first through n-th winding bundles are wound onto the first set of winding hooks in a same direction, and aligned on the first set of winding hooks. The first through n-th winding bundles are arranged in an order such that the first winding bundle is closest to an end of the small-aperture portion of the tapered piece, and the n-th bundle is farthest from the end of the small-aperture portion of the tapered piece.
