Problems solved by technology

[0002] At present, the stator core punching materials of electric motors at home and abroad are all made of cold-rolled silicon steel sheets. The production process of cold-rolled silicon steel sheets is many, the technical requirements are high, and the manufacturing cost is high. After being assembled into the motor core, the loss is relatively large.

Embodiment 1

[0014] An amorphous material with high magnetic permeability and low loss for a motor of the present invention, the amorphous material includes raw materials of 84.7% iron, 0.1% nickel, 0.1% cobalt, 0.01% iron, 0.01% manganese, and 10% boron , 0.04% carbon, 5% silicon, 0.04% phosphorus,

[0015] Amorphous materials use rapid solidification technology. The solidification speed of metals or alloys is very fast. The raw materials are cooled and solidified into thin ribs at a rate of 130°C / S, which is a solid thin strip with a thickness of 0.2mm. The atoms are frozen before they are neatly arranged. Stop, the final atomic arrangement is similar to that of a liquid, which is disordered, which forms an amorphous alloy.

Embodiment 2

[0017] An amorphous material with high magnetic permeability and low loss for a motor of the present invention, the amorphous material includes raw materials of 78% iron, 01% nickel, 0.5% cobalt, 0.1% iron, 0.1% manganese, and 13% boron , 0.2% carbon, 7% silicon, 0.1% phosphorus,

[0018] Amorphous materials use rapid solidification technology. The solidification speed of metals or alloys is very fast. The raw materials are cooled and solidified into thin ribs at a rate of 150°C / S. They are solid thin strips with a thickness of 0.15mm, and the atoms are frozen before they are neatly arranged. Stop, the final atomic arrangement is similar to that of a liquid, which is disordered, which forms an amorphous alloy.

Embodiment 3

[0020] An amorphous material with high magnetic permeability and low loss for a motor of the present invention has a very fast solidification speed of metal or alloy, and the amorphous material includes 70% iron, 2% nickel, 0.6% cobalt, 0.2% corium, 0.2% manganese, 14.7% boron, 0.3% carbon, 10% silicon, 0.2% phosphorus,

[0021] Amorphous materials use rapid solidification technology to cool the raw materials at a rate of 180°C / S and solidify them into thin ribs, which are solid thin strips with a thickness of 0.12mm. The atoms are frozen before they are neatly arranged, and the final atomic arrangement is similar to In liquid, it is disordered and disordered, which forms an amorphous alloy.

[0022] Rapid solidification is the extremely rapid transformation of a metal or alloy from a liquid to a solid state at a much faster cooling rate than in conventional processes. Metals and alloys are required to have a great degree of undercooling when they solidify. In recent years, ...

Abstract

The invention relates to a high-magnetic-permeability and low-loss amorphous material for an engine. The amorphous material comprises iron being 70-85% of raw materials, nickel being 0.1-2% of raw materials, cobalt being 0.1-0.6% of raw materials, chromium being 0.01-0.2% of raw materials, and manganese being 0.01-0.2% of raw materials; and the amorphous material uses a quick condensation technology for cooling and curing the raw materials to a solid thin strip with a thin rib shape and a thickness of 0.12-0.2 mm by the speed of 130-180 DEG C / S to form an amorphous alloy to obtain a finished product. Compared with the prior art, the amorphous material has the following advantages: the amorphous material is excellent in ferromagnetism, can reduce 80% of energy consumption generated by steel rolling, improves the magnetic permeability, reduces the magnetic hysteresis loss and the iron loss of the engine, has such characteristics as short production period, high yield, high mechanical strength and good corrosion resistance, and is an upgrading product of a traditional silicon steel sheet.

Description

technical field [0001] The invention relates to an amorphous material with high magnetic permeability and low loss for electric motors, which is used as stator core punching material for DC motors, AC motors, synchronous motors, asynchronous motors, permanent magnet synchronous motors and generators. Background technique [0002] At present, the stamping material of motor stator core at home and abroad is all made of cold-rolled silicon steel sheet. The production process of cold-rolled silicon steel sheet is many, the technical requirements are high, the manufacturing cost is high, and after being assembled into the motor core, the loss is relatively large. The requirements for the motor in the prior art cannot be met. [0003] Therefore, a new technical solution should be provided to solve the above problems. Contents of the invention [0004] The invention provides an amorphous material with high magnetic permeability and low loss for a motor. [0005] In order to ach...
