PROBLEM TO BE SOLVED: To provide a core applied with windings in which a torque generated at the coil end can be utilized effectively, while relaxing the magnetic saturation of the tees portion. SOLUTION: The core comprises a core section 10 having a yoke portion 11, a tees portion 12, and a tees end 13 and being constituted, by laminating a plurality of sheets of magnetic plate; an auxiliary magnetic core 20 having a tees laminating direction end face extension 20A, extending from the vicinity of the tees end to the root of the tees portion along the lamination direction end face of the tees portion 12, a laminating direction extension 20B for extending from the vicinity of the tees end of the tees lamination direction end face extension 20A to the outside of lamination direction; and a tees lamination direction side face extension 20C, extending from the tees lamination direction end face extension 20A, along the lamination direction end face of the tees portion 12 and attached to the core section 10; and a winding applied to the tees portion 12 of the core section 10, the tees lamination direction end face extension 20A of the auxiliary magnetic core 20 and the tees laminating direction side face extension 20C.
