PROBLEM TO BE SOLVED: To provide a motor which has a structure capable of reducing the manufacturing costs, and also, which can make a high safety ratio of the insulation to a high voltage and a high space factor in a slot of an exciting coil compatible. SOLUTION: In the concentrated winding type motor in which the rotational force is generated by exciting a magnetic pole by energizing the exciting coil 8 wound around the teeth 7 of a stator iron core 3 arranged in a frame 4, bolt holes 6 for mounting the motor are provided to the frame 4, and at the same time, the frame 4 and the stator iron core 3 are molded in an integral structure with magnetic powder.
