JPH054761U - Rotating electric machine stator core retainer cover plate - Google Patents

Abstract

(57) [Summary] [Purpose] Do not let the air flow in the exhaust chamber pass through to the intake chamber. [Structure] A stator core 1, a stator clamper 2, and a closing plate 8 that closes the space between the stator frames 4. [Effect] It is easy to attach the cover plate and the time can be shortened.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to the leakage of wind from a gap in the structure of a rotating electric machine.

[0002]

[Prior Art]

 FIG. 2 shows the structure of a conventional stator core end portion. In the figure, 1 is a stator core, 2 is a stator clamper, 3 is a stator coil, 4 is a stator frame, and 5 is a cover plate made of a steel plate.

Next, the operation will be described. As the rotor 6 rotates and operates, the fan 7 rotates to generate a wind flow. The wind passes through the stator coil 3 and the stator core 1 and cools them to the outside.

[0004]

[Problems to be solved by the device]

 Since the end portion of the conventional stator core is configured as described above, when the steel plate cover plate is attached, a gap is formed so that the vibration of the stator core is not transmitted to the stator frame. Therefore, there was a problem that it took a lot of time to adjust the clearance.

The present invention has been made in order to solve such a problem, and can be mounted without adjusting the clearance, and the problem can be solved.

[0006]

[Means for Solving the Problems]

 The present invention uses a flexible molded article for the covering plate.

[0007]

[Action]

 In this invention, the cover plate absorbs the vibration from the stator core and makes it difficult to transmit the vibration to the stator frame.

[0008]

【Example】

 Example 1. FIG. 3 shows an embodiment of this invention. Items 1 to 4 are exactly the same as the above conventional device. Reference numeral 8 is an occlusion plate which requires flexibility.

When the rotor 6 rotates and operates, the fan 7 turns around to generate a wind flow. The wind passes through the stator coil 3 and the stator core 1 and cools them, respectively, and then goes out. At that time, the wind in the exhaust chamber does not flow into the intake chamber due to the flexible closing plate.

[0010]

[Effect of the device]

 As described above, since the cover plate is made of a flexible material, there is no need to adjust the clearance when installing the cover plate, and the work time is shortened.
