Abstract

PURPOSE:To obtain a stator which is excellent in working property at the time of production and can effectively radiated the generated heat of a stator winding, by sealing insulation liquid to be heat medium in a space section in a stator frame so that said liquid may be provided in contact with the stator core and stator winding. CONSTITUTION:A stator core 1 is wound up with a stator winding 2, and the stator for a canned motor is provided with a can 6 arranged at the inner diameter section of the winding and with a stator frame 3 outside the can, and insulation liquid 7 for heat medium is sealed so that said liquid may be provided in contact with the stator core 1 and stator winding 2 in the stator frame 3. So far as the insulation liquid 7 is concerned, fluoric inert liquid or the like which is excellent in electric insulating property and thermal conductivity is effective. As a result, the liquid 7 is gasified with the generated heat of the stator winding 2, and after the radiation in an upper space 9, the cycle for the gasification is repeated, thereby said liquid is excellent in radiation effect, and in working property because labor only for sealing the liquid is required.

Conventionally, as shown in Japanese Patent Publication No. 52-13603, this glaze has been used for stator windings and stator cores.
Some stator frames are filled with resin to harden the stator frame, but the above-mentioned resin is expensive, and the heat curing during the filling is 8
Is there a lot of trouble in IM construction, such as recognition? However, the present invention has problems such as poor productivity, and the above-mentioned stator windings being heated, causing the can to form and causing an electric VJ locking accident. [Summary of the Invention] This invention 1) Insulating liquid as a VC heat medium in the stator frame? Compared to encapsulating VC, manufacturing workability is improved, and L,
