Compared with the traditional electric excitation motor, the permanent magnet motor has obvious advantages such as simple structure, reliable operation, small size, light weight, low loss, high power, flexible and diverse motor shapes and sizes. Compared with the permanent magnet motor produced with the traditional NdFeB magnet permanent magnet material, the new permanent magnet motor using the high-performance NdFeB magnet permanent magnet material is smaller in size, lower in loss, and significantly higher in power than the traditional permanent magnet motor.
In the 1840s, British physicist James Joule discovered that iron-based NdFeB magnet materials change their shape when placed in a magnetic field, but retain the same volume. This phenomenon is called "Joule magnetostriction," and in the 175 years since its discovery, all magnets have exhibited this feature.
In the past 10 years, as the post-80s and 90s have gradually become the main labor force in the manufacturing industry, they are no longer willing to engage in a large number of monotonous, repetitive and poor environmental jobs. Labor shortages are frequent, resulting in a rapid rise in labor costs in my country's manufacturing industry. According to statistics, in the past decade, the minimum wage in developed regions such as Beijing, Shanghai, Zhejiang, Guangdong, and Jiangsu has maintained an average annual compound growth of about 10%. The rapid rise in labor costs has spawned an increase in China's demand for industrial robots, which will also bring opportunities for the development of industrial robot power core NdFeB magnets materials.
For a long time, the use of NdFeB magnets is very common. With the change of time, the era of science and technology continues to move forward, and the use of NdFeB magnets has become more and more obvious. Deko NdFeB magnets not only have small size, light weight and strong magnetic properties, but also are the most reasonable and best magnets in this society. The most important raw materials of NdFeB magnets are neodymium metal, pure iron, iron boron alloy and other additives, so NdFeB magnets have such good performance. Although magnets bring us a lot of convenience, they also have certain harms. For example, magnetic electronic products such as keyboards and bank cards will be magnetized by magnets.
Deko Strong NdFeB magnets are devices that convert changes in the magnetic function of active components caused by magnetic fields, currents, stress and strain, temperature, light, etc., into electrical signals, and use this method to view the corresponding physical quantities. It is characterized by non-contact measurement, the viewing signal is hardly affected by the measured object, pollution resistance, strong noise, reliable operation even under very harsh environmental conditions, sturdy and durable, and long life. Because of this, such sensors are used in many aspects from defense, aerospace to the national economy, from medical and health care to the daily life of human beings.
NdFeB magnets are very easy to corrode. Therefore, most finished products need to be plated or coated. Conventional surface treatment includes: nickel plating (nickel copper nickel), zinc plating, aluminum plating, electrophoresis, etc. If working in a closed environment, phosphating can also be used.
