PROBLEM TO BE SOLVED: To provide a motor less in the aged deterioration of the insulation performance of a stator winding and high in efficiency and reliability. SOLUTION: A divided core 1 is formed by laminating electromagnetic steel plates whose pole tooth units are divided in the circumferential direction, and a slot insulating plate 2 that insulates an opening of a pole tooth 1a is sandwiched by an end insulator 5 that individually insulates both ends and subjected to insulation treatment. Weather-resistance synthetic rubber (such as NBR) is used for an insulating body 4 having elasticity, and on the slot insulating plate 2 wound with a winding 3 of the pole tooth 1a, the rubber is adhered and fixed so as to be thick at the center of the lamination direction of the divided core 1, and thin at its both ends in advance. After that, stator pieces are formed by being wound with the winding 3 so as to be orthogonal to the pole tooth 1a while aligning the winding, and a stator is formed by connecting the pieces after annularly coupling them a prescribed number of times.
