部から支持部材を通じて侵入し、超電導コイルの存在す
る液体ヘリウム温度部に熱か侵入することになる。When a superconducting coil is used as a coil in the stator section of a superconducting motor, a large force is generated in the superconducting coil when the motor is started. For this purpose, this superconducting coil must be supported and fixed to the superconducting motor case in some way, but since this superconducting motor case exists in a room temperature space, it is impossible for the superconducting coil to enter from the room temperature part of the superconducting motor case through the support member. However, heat will enter the liquid helium temperature area where the superconducting coil is located.

か知られている。In order to maintain the superconducting state of the superconducting coil, it is necessary to prevent the invading heat from reaching the liquid helium temperature section. Furthermore, it is necessary to prevent heat from entering the liquid helium temperature area because a huge amount of energy is required to discharge the heat that has entered the cryogenic region to the room temperature space. Conventionally, as a technology for maintaining a superconducting state, a so-called cryostat is generally known, which is a structure in which a liquid nitrogen tank surrounds and insulates a liquid helium tank in which a superconducting coil is immersed.

する。In this way, the superconducting maintaining temperature section, for example, the liquid helium temperature section, is surrounded by the intermediate temperature section, for example, the liquid nitrogen temperature section, and in the present invention, the superconducting maintaining temperature section and the surrounding intermediate temperature section have an insulating structure. This part is called the cryo part. In order to support this cryo section, there is a problem of heat intrusion from the outside through the support member. In addition, in order to support and fix this cryo section, the thin cylindrical partition wall that separates the rotor and stator is weak in strength and has a small thermal capacity (and since it is located extremely close to the superconducting coil, Therefore, the present invention securely supports and fixes the cryo section to the case of a superconducting motor, makes its assembly easy, and also prevents intrusion from the outside by using the supporting member. An object of the present invention is to provide a superconducting motor that prevents heat from reaching a superconducting temperature section.
