A brief discussion on the superconducting magnet of tongmao linear motor that affects every aspect of life. There is a common existence in nuclear magnetic resonance, magnetic levitation train, and other hardcore equipment, that is, superconducting magnet. Some people compare superconducting magnet to "bisexual person". On the one hand, it is very tsundere, very picky about temperature, current, magnetic field and other working environment. On the one hand, it is very powerful. Superconducting magnets can generate thousands of times larger magnetic fields than ordinary permanent magnets and conventional wire electromagnets.

The technology related to superconducting magnets not only affects every aspect of people's lives, according to tongmao linear motor small series, is also a frequent winner of various awards. According to statistics, research achievements related to strong magnetic field have won 19 Nobel prizes, including 1 prize for medicine, 5 prizes for chemistry and 13 prizes for physics.

In addition, with MAO linear motor small make up to talk about superconducting magnets in the past life. In 1911, Dutch scientist heike kammerin onnes discovered the superconductivity of mercury and proposed the idea of using superconducting wires to wrap electromagnets. However, due to the limitations of superconducting materials and manufacturing technology, it was not until 1955 that another scientist, g. byntema, made a superconducting magnet made of niobium wire and obtained a magnetic field of 0.7T at 4.2k. In 1961, j. e. kunzler et al. used the Nb3Sn superconducting material to wind a superconducting coil capable of generating a magnetic field close to 9T. More than 50 years later, in 2019, laomei inserted 14.4t HTS interpolation coil into the background magnet of 31.1t water-cooled magnet, and generated a magnetic field intensity of 45.5t in the center of the coil, setting a new world record for steady-state strong magnetic field.

In addition, tongmao linear motor small series would like to say that many practical applications of superconducting magnets coincide with the linear motor, the linear motor is a magnetic levitation train traction device, is also used to drive nuclear magnetic resonance inspection bed for linear motion.

Kunshan tongmao has been continuously improving the efficiency and productivity of the complex manufacturing process for more than ten years. Its products such as tongmao linear motor, linear module, linear sliding table, voice coil motor and voice coil module have been trusted by customers at home and abroad.
