Abstract
The present invention relates to a stator for a linear motor by staggered core lamination which can facilitate insulation and assembly of a stator core, can freely set an interval of an opening of the stator core, and can reduce loss of the motor by decreasing a magnetic flux density of the core. The stator for the linear motor includes a stator coil formed by winding and insulating a coil at a cylindrical shape, a vertical unit consisting of a thin plate material, and having a predetermined width and length, a horizontal unit curved and extended in a right angle at one end portion of the vertical unit, and a plurality of core strips having pole parts gradually extended at an edge portion of the horizontal unit, and forming an inverted triangle shape, an inside edge portion of the vertical unit of the core strip being connected to an outer circumferential surface of the stator coil, an inside edge portion of the horizontal unit being connected to upper and lower surfaces of the stator coil, or alternately connected therewith having a predetermined interval, and laminated in a radial shape, edge portions of the pole parts of the core strips being connected to one another, and forming an inner circumferential surface, outside end portions of the vertical units forming an outer circumferential surface.
