PROBLEM TO BE SOLVED: To obtain a stator capable of reducing the surface loss of a rotor without deteriorating the workability of a winding for an armature coil because the reduction of the surface loss of the rotor and the workability of the winding for the armature coil cannot coexist in conventional stators. SOLUTION: The stator has a plurality of stator teeth sections 9 having extending sections extending in the axial direction of a cylinder from a cylindrical outer frame 9a while projecting in the shaft central direction of the cylinder. The stator teeth sections 9 are mounted so as to straightly project as broad thickness in the direction orthogonal to the surfaces of the extending sections is left as it is fixed broad thickness towards a shaft center, and magnetic stays 7 installed so as to project in the direction of the adjacent stator Ts sections 9 from both surface sides of the extending sections on the front end sides of the stator teeth sections 9 are set up on the front end sides of the stator teeth sections.
