It can be easily performed without being disturbed.

The lower end of the slit 21 e of the housing 26 is opposed to the axial end face of the rotor 14. For this reason, moisture in the housing 26 drips down to the rotor 14 through the lower end of the slit 21e.
This prevents the water in 6 from dripping onto the main coil 16 and the auxiliary coil 17 and deteriorating the main coil 16 and the auxiliary coil 17.

It is possible to prevent the water in the main coil 16 and the auxiliary coil 17 from dripping onto the main coil 16 and the auxiliary coil 17 to prevent the main coil 16 and the auxiliary coil 17 from being deteriorated.

Since the width of the slit 21e of the housing 26 and the width of the slit 21g of the terminal block main body 21 in the short direction are set to 1 mm or more, the water in the housing 26 is not affected by the surface tension and the slits 21e and 21g are not affected.

A slit 21g is formed in the terminal block main body 21, and the slit 21e of the housing 26 and the shaft hole 2 are formed.
The space between 1f was communicated with the slit 21g. For this reason,
Since the creeping distance between the connection portions 22b of the conductor plate 22 is further increased, the insulation performance is further improved.

Further, a projection 21c is provided on the bottom surface of the capacitor housing 21b. For this reason, the capacitor storage section 21b
When the urethane resin is injected into the inside, the urethane resin enters the gap between the main body 23a of the capacitor 23 and the bottom of the capacitor housing 21b, and the bottom of the main body 23a is covered with the resin. Therefore, even when moisture penetrates the inner surface of the capacitor housing portion 21b and enters the bottom surface, the main body portion 23a is prevented from getting wet with water, so that the moisture resistance of the capacitor 23 is improved.

Further, since the plurality of protrusions 21c are arranged apart from each other, a gap for resin distribution is formed between the protrusions 21c. Therefore, the urethane resin easily enters the gap between the main body portion 23a of the capacitor 23 and the bottom surface of the capacitor housing portion 21b, so that the bottom surface of the main body portion 23a is securely covered with the resin and the urethane resin injection work is easy. become.

It faces the end face.

According to the above embodiment, since the slit 21h is formed in the bottom plate of the housing 26, the water in the housing 26 drips from the slit 21h. For this reason, since it becomes difficult for water to accumulate in the housing 26,
The tracking resistance between the conductor plates 22 is increased, and the insulation performance is improved.

Further, since the width of the slit 21h in the short direction is set to 1 mm or more, the water in the housing 26 is smoothly dropped from the slit 21h without being affected by the surface tension. For this reason, since it becomes more difficult for water to accumulate in the housing 26, the insulation performance is further improved.

The slit 21h is opposed to the axial end face of the rotor 14. This prevents water from dripping from the slit 21h onto the main coil 16 and the auxiliary coil 17, so that the main coil 16 and the auxiliary coil 1
