It should be noted that the application of different types of magnets in motors is not absolute, and the specific selection should be comprehensively considered according to factors such as the working conditions of the motor, performance requirements, and manufacturing costs.

The design principle of the magnetic coupler is to convert the rotational power of the drive shaft into a magnetic field through the magnetic force, and then act on the magnetic coupler of the driven shaft through the magnetic field, so as to realize the transmission between the two shafts. The magnetic coupling does not require mechanical contact, so it can avoid the wear of traditional mechanical parts such as bearings and seals, and can also prevent liquid or gas leakage. This makes magnetic couplers particularly suitable for applications with high precision, high reliability, and high hygiene.

Magnetic couplers have many advantages, such as no contact, no wear, no friction, good sealing, etc. Therefore, it is widely used in many fields, such as chemical industry, medicine, food, water treatment, semiconductor manufacturing, aerospace and so on.

In general, the design principle of magnetic filter equipment is to generate a magnetic field through magnetic materials to absorb ferromagnetic impurities in the fluid, thereby achieving the filtering effect. These spare parts usually have product characteristics such as high magnetic force, easy cleaning and maintenance, and compact structure, and are suitable for various fluid filtration fields, such as chemical, food, pharmaceutical, etc.
