The present invention will be explained below based on the illustrated embodiments. An embodiment of the invention is shown in FIGS. 2 and 3. Note that parts that are the same as those in the conventional system are given the same reference numerals, and therefore their explanations will be omitted. In this embodiment, the fixing member is formed of a cylinder 7 that covers the stator coil end 2 on the rotor side through a predetermined gap and is integrated with the ring 4, and this cylinder 7 is fixed to the stator core 1. did. By doing this,
The rotating flow of liquid due to the rotation of the rotor impinges on the cylinder 7, thereby making it possible to obtain a stator coil end support device for a liquid immersed motor that makes it possible to reduce the vibration of the stator coil end 2.

せず、電動機の特性が損なわれることがない。 That is, a cylinder 7 that is integrated with the ring 4 and covers the stator coil end 2 on the rotor side with a predetermined gap is fixed to the stator core 1. and cylinder 7
A hole is provided on the outer peripheral surface of the ring 4 for passing the bind 3 that fixes the ring 4 to the stator coil end 2, the bind 3 is passed through this hole, and the stator coil end 2 is bound, and the bound bind 3 is treated with resin. The ring 4 was fixed to the stator coil end 2. By doing this, the rotating flow of liquid, such as water, caused by the rotation of the rotor hits the cylinder 7 and does not hit the stator coil end 2, making it possible to reduce the vibration of the stator coil end 2 compared to before. . Since it is no longer necessary to fix the ring 4 to the frame with an arm as in the conventional case, not only can the installation area of the stator coil end 2 be reduced, but also the cylinder 7 can be attached to the stator coil end 2 as described above. Since it was provided with a predetermined gap between
Even if the stator coil end 2 vibrates, it does not come into contact with the cylinder 7 and damage the stator coil end 2, and the rotating flow of water no longer hits the stator coil end 2 directly. Wear of the stator coil ends 2 due to rotational flow can be prevented.
Furthermore, since the ring 4 and cylinder 7 are formed from voidless epoxy laminated tubes made of glass cloth, which is a fiber-reinforced plastic, no eddy current loss occurs in the ring 4 and cylinder 7 due to leakage magnetic flux, and the motor properties are not impaired.
