The stator of asynchronous motor is composed of stator core, stator winding and frame. The stator core is a part of the magnetic circuit of the motor, which is used to insert the stator winding and provide the magnetic path.

In recent years, the rapid development of the global new energy vehicle market has made the demand for thin-gauge silicon steel begin to increase, especially the progress of rapid self-bonding coating technology, which has greatly pulled the demand for thin-gauge and ultra-thin/ultra-thin silicon steel in the high-end motor market such as drive motors, high-speed motors, and micro-motors.

Fast self-bonding coated electrical steel core is an inevitable trend in the application of new energy vehicle drive motors and micromotors. Self-bonding coating and fast self-bonding coating process is a new process and new material, mainly used in the production of large generators, high-speed magnetic levitation motor core and new energy vehicle drive motor core.

According to the requirements of Q/GDW11744-2017 National Grid enterprise standard, the construction of UHV power grid project will mainly use high magnetic induction oriented electrical steel (HiB), The grades are 23QG080, 23QG085, 23QG090, 27QG085, 27QG090, 27QG095, 27QG100, 30QG100, or higher.

The microstructure uniformity of hot rolled plate can be improved by adjusting chemical composition, refining casting grain, adjusting hot rolling process and regularization after hot rolling.

2024 is the key sprint year of China's "14th Five-Year Plan". In order to seek progress in stability and continuously stimulate domestic demand, the country has introduced a series of policies to promote the high-quality development of the electrical steel industry, and also bring opportunities and challenges.

Non-oriented silicon steel prices are stable this week, and market traders are shipping normally. However, the amount of terminal purchases is small, and the festive atmosphere is gradually increasing.

Due to the increase in demand for electrical steel in the automotive industry, electrical products have also begun to use more electrical steel. In addition, the industry has also put forward a new requirement: the development of ultra-thin electrical steel products with a thickness of 0.25mm and below.
