Reference numeral 4 denotes a stator core, and reference numeral 5 denotes a coil wound around the stator core 4. As shown in this figure,
Generally, a method of inserting and fixing the stator core 4 into the inner peripheral surface 1A of the steel plate frame 1 by press fitting is used.

Is a cooling fin mounted on the outer periphery of the steel plate frame 1 by welding or the like, 4 is a stator core, 5 is a coil wound around the stator core 4, 7 is a load side bracket, 8 is a non-load side bracket, 9 is a bearing. The rotor 10 is a rotor part, and is supported by the load side bracket 7, the non-load side bracket 8, and the bearing 9. Also, a steel plate frame 1,
The load-side bracket 7 and the non-load-side bracket 8 are integrally fixed from the non-load side with bolts or the like. Reference numeral 11 denotes a fan coupled to the rotor 10, and 12 denotes a cover for protecting the fan 11. The wind from the fan 11 rotating together with the rotor 10 during operation of the rotating electric machine cools the outer periphery of the steel plate frame 1.

The rotating electric machine has a mechanism for applying a predetermined alternating current to a coil 5 wound around the stator core 4 and generating a torque by the generated rotating magnetic field. The coil 5 is a heating element, and the temperature rises. . Most of the heat generated inside the rotating electric machine is radiated to the outside from the stator core 4 through the steel frame 1, so that the heat conduction between the steel frame 1 and the stator core 4 improves the heat radiation to the outside. It will affect the evil.

[0005]

Here, in the above prior art, due to the following items, a slight gap is generated between the fitting portion between the inner peripheral surface of the steel plate frame and the outer peripheral surface of the stator core.

You can't do that.

First, as shown in FIG. 8, the stator core 4 is generally manufactured by stacking a required number of thin iron plates cut to a thickness of about 0.5 mm. For this reason, since the outer peripheral surface 4A of the stator core 4 is not smooth and has a very slight step, when the stator core 4 is inserted into the steel plate frame 1, the inner peripheral surface 1A of the steel plate frame 1 A gap 12 is formed between the outer peripheral surfaces 4A of the stator core 4.

Next, as shown in FIG. 9, cooling fins 2 and mounting feet 3 for improving cooling performance are generally attached to the outer peripheral surface of the steel plate frame 1 by welding or the like.
The welded portion of the inner peripheral surface 1A of the steel plate frame 1 after welding is deformed due to thermal distortion to become a convex portion, and when viewed over the entire circumference, it becomes not a circumferential surface but a very slightly uneven state. Therefore, when the stator core 4 is inserted into the steel frame 1 after winding the coil 5, a gap 13 is formed between the inner peripheral surface 1 </ b> A of the steel frame 1 and the outer peripheral surface 4 </ b> A of the stator core 4. .
