Market scale analysis of high speed motor stator rotor industry
The stator and rotor account for 30% of the output value of the motor.
From the perspective of the output value of the motor, although the motor has many specifications and types, the structure is roughly the same, including the stator, the rotor, the end cover, the bearing cover, the bearing, the junction box, the lifting ring, the hood and the cooling fan. As the core component, the fixed rotor accounts for nearly 30% of the total output value of the motor components.
Data show that in 2012-2018, China's high-speed motor manufacturing industry sales revenue growth trend, but the growth rate has slowed down. In 2012, the sales revenue of the high-speed motor manufacturing industry was 2.27 billion yuan; in 2018, the sales revenue of the high-speed motor manufacturing industry was 3.631 billion yuan, a year-on-year increase of 5.92%, and the compound annual growth rate in 2012-2018 was 8.14%.
According to the calculation of the output value of the stator and the rotor in the motor component 30%, the sales revenue of the high-speed motor stator and rotor industry can be roughly estimated. In 2012, the sales revenue of high-speed motor stator and rotor industry was about 681 million yuan; by 2018, sales revenue was close to 1.1 billion yuan, reaching 1.089 billion yuan.
Analysis of development trend of stator rotor technology
The development goal of the stator and rotor chip and core production technology is to continuously improve the conversion efficiency of electric energy and mechanical energy through the research and improvement of the basic materials and the improvement of the production technology, while reducing the material consumption and improving the production efficiency. Therefore, the development trend of high-speed motor stator and rotor technology is mainly reflected in the research and development of basic materials, mold design and manufacturing, improvement of processing technology and improvement of production equipment level.
