Definitions

  • the present invention relates to a composite laminated soft magnetic ribbon in which soft magnetic ribbons such as a silicon steel sheet ribbon, an amorphous alloy ribbon, and a nanocrystalline alloy ribbon are laminated.
  • soft magnetic ribbons such as a silicon steel sheet ribbon, an amorphous alloy ribbon, and a nanocrystalline alloy ribbon are laminated.
  • This field relates to the manufacture of cores for transformers, reactors, toroidal cores, bulk laminates, stator cores, rotor cores, magnetic circuits, etc. for motors and generators, using composite laminated soft magnetic ribbons.
  • Amorphous alloy ribbons are produced by rapidly cooling from a molten state, and are in a state in which they do not retain a crystal structure at the atomic level, and do not retain a specific periodic structure when observed with an electron microscope or X-ray diffraction. For this reason, normally, an amorphous alloy ribbon produced in a rapidly cooled state is subjected to strain relief annealing at a temperature lower than the crystallization temperature to further make it soft magnetic before use. Since the amorphous alloy ribbon is produced by rapid cooling from a molten state, the width of the ribbon is approximately 20 cm. At present, the manufacture and use of wide ribbons is limited. Although soft magnetic ribbons with various characteristics can be manufactured from amorphous alloy ribbons, the types that are generally sold are limited.
  • Silicon steel sheet ribbon which is one type of soft magnetic ribbon, has a high saturation magnetic flux density, so the volume and weight of magnetic parts can be reduced.
  • Amorphous alloy ribbons and nanocrystalline alloy ribbons have magnetic properties such as magnetic permeability and iron loss that surpass those of silicon steel sheet ribbons, and their magnetic parts are excellent in energy conservation.
  • Nanocrystalline alloy ribbons have good magnetic properties, including magnetostriction, so they are increasingly being applied to magnetic parts, but their only drawback is that they have low rigidity. If magnetic parts are optimally made from amorphous alloy ribbons, the energy efficiency of transformers and motors can be over 97%, making them suitable for energy conservation. Furthermore, since nanocrystalline alloy ribbons have low magnetostriction, there is a high possibility that restrictions on manufacturing such as processing and molding will be relaxed.
  • Amorphous alloy ribbons and nanocrystalline alloy ribbons generally have a thickness of about 0.03 mm, which is much thinner than silicon steel sheets, so eddy current loss is small, and they are often used by winding and stacking them.
  • each soft magnetic ribbon has advantages and disadvantages in its characteristics, and sufficient performance cannot be obtained even if a magnetic component is constructed by using only one soft magnetic ribbon.
  • Patent Document 1 in order to ensure mechanical strength and rigidity, which are the only drawbacks of the nanocrystalline alloy laminated core, a support member that sandwiches a nonmagnetic material in the lamination direction of the laminated blocks is used.
  • Patent Document 2 as a manufacturing method for a wound core, a part of an amorphous alloy ribbon that can be nanocrystallized is crystallized, and amorphous alloy ribbons with similar shrinkage rates are selected to produce a nanocrystalline alloy thin film with stable characteristics. Stable properties are obtained by selectively nanocrystallizing and heat-treating the bands.
  • an amorphous iron core transformer is manufactured by abutting amorphous alloy ribbons and stacking large, wide amorphous alloy ribbons in such a manner that the abutting surfaces are offset.
  • Patent Document 4 discloses a method in which three rolls of soft magnetic alloy ribbons are pasted together with epoxy resin coating and laminated into one roll, and two types of thermosetting resins with different glass transition temperatures are used to form a laminate of soft magnetic alloy ribbons. It's glued.
  • stator and rotor of a motor are manufactured by punching silicon steel plates and laminating them.
  • Amorphous alloy ribbons and nanocrystalline alloy ribbons are thin and hard, and the life of the punching die is short, and the process of collecting, handling, and stacking the punched ribbons is time-consuming. Not suitable for making.

  • Patent Document 6 a laminate is manufactured by laminating soft magnetic alloy ribbons by adhesion while applying a resin, and bonding them under heat.
  • Non-Patent Document 1 examines the characteristics of a nanocrystalline alloy ribbon applied to the core of a transformer.
  • Non-Patent Document 2 describes a low-loss amorphous core structure configured to maintain the shape of the core by cutting and laminating amorphous metal foil strips and inserting them into a core holding member made of resin.
  • Small nanocrystalline alloy laminated ribbons can be made more rigid by molding, etc., but in order to ensure mechanical strength and rigidity, which is the only drawback of large nanocrystalline alloy laminated ribbons, they must be supported by a transformer core. There is a problem that parts are required. Furthermore, when the nanocrystalline alloy laminated ribbon is used in the core of a motor or generator, noise, vibration, etc. may occur due to deformation due to tensile force or repulsive force caused by external force. Transformers that use amorphous alloy ribbons with high magnetostriction produce a lot of noise. Currently, the maximum width of a ribbon that can be manufactured for both amorphous alloy ribbon and nanocrystalline alloy ribbon is about 20 cm. In order to manufacture large-sized magnetic products, it is necessary to develop a wide composite laminated soft magnetic ribbon. Because nanocrystalline alloy ribbons are heat treated before being laminated, they may become more brittle than before the heat treatment.

Inferior. For this reason, although the volume and weight of magnetic parts increase, from the viewpoint of energy saving, the development of transformers, motors, etc. mainly made of amorphous alloy ribbons and nanocrystalline alloy ribbons is progressing. In order to fabricate a large transformer using a nanocrystalline alloy ribbon, it is necessary to reinforce it with a non-magnetic support material to compensate for its low rigidity.
