In addition to the axial magnetization, radial magnetization, thickness magnetization, and multi-pole magnetization that we often hear about magnets (magnetic steel), there are also internal magnetization and external magnetization. What are internal magnetization and external magnetization? Woolen cloth? Next, this article will introduce the meaning of internal magnetization and external magnetization and their advantages and disadvantages.
What is internal magnetization and external magnetization?
The shape of the inner magnetized and outer magnetized magnets is mainly arc-shaped, ring, and most of them are radially magnetized. If the inner magnetization is used, the inner arc or inner circle of the arc-shaped or ring-shaped magnet has strong magnetism, and the outer magnetized magnet has strong magnetic properties. The outer arc or outer circular surface has strong magnetic properties, and is mostly used in DC motors, sensors and other fields.
What are the advantages and disadvantages of internal magnetization and external magnetization?
The disadvantage of radial outer magnetization is that the magnetic field is required to be large and there are many windings. The advantage is good heat dissipation.
The disadvantage of radial inward magnetization is that the winding is limited and the heat dissipation is not very good. The advantage is that it is easy to charge and saturate, and the structure is simple.
The above is the meaning advantages and disadvantages of internal magnetization and external magnetization introduced to you by courage, the manufacturer of motor magnetic ring. If you have motor magnet procurement, engineering or procurement friends who ask for samples or questions, please contact the online customer service on the website to serve you.
