Non-oriented electrical steel is a special steel used in the manufacture of electrical equipment such as motors, transformers and generators. Its main features are low magnetic permeability and high resistivity, which can effectively reduce eddy current loss and Joule heat loss. In this article, we will discuss the development and product characteristics of non-oriented electrical steel.

Development history of non-oriented electrical steel

Non grain oriented electrical steel originated in the early 20th century. At that time, with the development of the electrical industry, the efficiency requirements for power equipment were getting higher and higher. However, the motors and transformers of the time used ordinary steel and were therefore inefficient. In order to solve this problem, scientists began to study special electrical steels. The original electrical steel is grain-oriented electrical steel, its magnetization direction is fixed, so strict orientation and processing are required in the manufacturing process. But this kind of steel has great limitations, such as iron loss, noise and vibration are prone to problems.

With the continuous development of science and technology, non-oriented electrical steel has gradually been widely used. Non-oriented electrical steel can be placed freely in motors and transformers without directional processing, so it can better reduce iron loss, noise and vibration problems. At present, non-oriented electrical steel has become the main material of motors and transformers, and is widely used in the fields of automobiles, electric power, industry and home appliances.

Cold rolled Non oriented electrical steel


Non-oriented electrical steel has the following characteristics:

Low iron loss

The hysteresis loop area of non-oriented electrical steel is small, and the iron loss is reduced. This reduces heat generation, extends equipment life, and improves equipment efficiency.

Low noise

Non-oriented electrical steel has a smoother surface that reduces hysteresis and core noise. At the same time, the thickness of the non-oriented electrical steel is relatively thin, which can reduce air noise and eddy current noise.

High strength

Non-oriented electrical steel has high strength, which can improve the mechanical strength and stability of equipment. At the same time, non-oriented electrical steel has high hardness and can effectively resist deformation and wear.

Excellent processing performance

Non-oriented electrical steel has good processing performance and can better meet the requirements of different equipment.
