micro-motor development trend
After entering the 21st century, the sustainable development of the world economy faces two key issues: energy and environmental protection. On the one hand, human society is progressing, people's demands for quality of life are getting higher and higher, and environmental awareness is getting stronger and stronger. The special motor is not only widely used in industrial and mining enterprises, but also used in commercial and service industries. In particular, more products enter the family life, so the safety of the motor directly endangers personal and property safety; vibration and noise of the motor, Electromagnetic interference will become a public hazard to pollute the environment; the efficiency of the motor is directly related to energy consumption and harmful gas emissions. Therefore, the requirements for these technical indicators are becoming more and more stringent internationally, which has attracted the attention of the motor industry at home and abroad. Energy-saving research has been carried out in many aspects such as process, materials, electronic components, control circuits and electromagnetic design. The new round of products of Micro-motors will be based on energy-saving and environmental protection. International standards to promote relevant technological advances, such as new motor punching, winding design, ventilation structure improvement and low loss high permeability materials, Research on rare earth permanent magnet materials, noise reduction and vibration reduction technology, power electronics technology, control technology, and reduction of electromagnetic interference technology.
As the trend of economic globalization accelerates, countries pay more attention to the two major issues of energy conservation and environmental protection, international technology exchanges and cooperation are strengthened, and the pace of technological innovation is accelerating. The development trend of micro-motor technology is:
(1) Adopting high and new technology to develop in the direction of electronic;
(2) High efficiency, energy saving and green development;
(3) Development towards high reliability and electromagnetic compatibility;
(4) To low noise, low vibration, low cost, and price development;
(5) Development towards specialization, diversification and intelligence.
In addition, Micro-motors are moving toward modularization, combination, intelligent mechatronics and brushless, iron-free, and permanent magnetization. Especially worthy of attention is the large-scale application of micro-motors, environmental Changes, the traditional electromagnetic principle motor can not fully meet the requirements. The development of micro-motors with non-electromagnetic principles has become an important direction for the development of motors with new results from related disciplines, including new principles and new materials.
