Claims

[Scope of Claim for Utility Model Registration] 1. In a motor core in which a laminated core yoke and a laminated core having salient poles are wound, the lamination direction of the core is substantially perpendicular to the lamination direction of the yoke, and concentrated winding is applied at both ends. A motor core comprising a laminated salient pole core provided with a recess for accommodating a coil end portion in order to reduce the portion of the coil end portion protruding from a yoke end face. 2. In a rotary motor core in which a wire is wound around a laminated core yoke and a laminated core having salient poles, the stacking direction of the cylindrical laminated core yoke and the core attached to the inner diameter of the yoke is approximately perpendicular to the stacking direction of the yoke. A motor iron core comprising a laminated salient pole core with a recess provided at both ends to house the coil end in order to reduce the portion where the end part of the concentratedly wound coil protrudes from the end face of the yoke. 3. In a linear motor core in which wires are wound around a laminated core having salient poles, a laminated C-shaped core is fixed to the center of the C-shaped core, and the lamination direction is approximately perpendicular to the lamination direction of the C-shaped core. , a motor core comprising a laminated salient pole core with recesses provided on both sides to accommodate the coil ends in order to reduce the portion of the end portions of the concentratedly wound coil protruding from the end face of the core.
