What are internal magnetization and external magnetization?

The shapes of magnets for internal and external magnetization are mainly arc-shaped, circular in shape, and mostly radially magnetized. For internal magnetization, the inner arc or inner circle of the arc-shaped or annular magnet is strong in magnetism, while for external magnetization, the outer arc or outer circle of the magnet is strong in magnetism. It is commonly used in DC motors, sensors, and other fields.

What are the advantages and disadvantages of internal and external magnetization?

The disadvantage of radial magnetization is that it requires a high magnetic field and requires a lot of winding. The advantage is good heat dissipation.

The disadvantage of radial internal magnetization is limited winding and poor heat dissipation. The advantage is easy saturation and simple structure.

The above is the meaning, advantages and disadvantages of internal and external magnetization introduced to you by the editor of the motor magnetic ring manufacturer.
