Trapezoidal magnet is a specially shaped permanent magnet, usually made of neodymium-iron-boron material. It has a large end face and a small end face, two sides are beveled, and the overall shape is like a trapezoid in math.
Advantages of the trapezoidal magnet shape;
The trapezoidal, beveled design creates a unique distribution of magnetic field, causing the magnetic lines of force to show a focusing or diverging effect.
Multiple trapezoidal magnets can be perfectly combined to form a circular or toroidal structure, which is particularly suitable for use in rotating equipment such as motors and generators
Trapezoidal structures are also easy to mount and secure, and excel in applications where a specific angular magnetic field is required.
Dimensional drawings of trapezoidal permanent magnets;
General steps for customizing trapezoidal permanent magnets;
1. Determine the basic parameters. Such as the dimensions of the large and small end faces (length and width), magnet height, tilt angle or bevel length, and the desired magnetization direction (axial, radial, or other).
2、Choose the magnet grade. Choose the appropriate NdFeB grade according to the usage environment (e.g. N35-N52), consider the working temperature to choose the appropriate temperature grade (M, H, SH, UH, etc.), and decide whether plating is needed according to the usage environment (nickel-plated, zinc-plated, epoxy, etc.).
3、Drawing drawings. Draw the trapezoidal magnet, indicating the technical requirements.
4、Sample making. Contact magnet manufacturers to make samples for testing and verification.
5、Test and evaluation. Test the samples for magnetic properties and dimensional accuracy.
6、Mass production. After confirming the samples, mass production will be carried out.
