What Are Wedge Magnets?

In the magnet industry, in addition to the common circular, square, and ring shapes, there is also a relatively special shape called the wedge shape. Many people may find it unfamiliar when they first hear it, but it is actually what we call an arc shape, It can be seen as a part of a ring.

The biggest feature of a wedge magnet is that its shape is not a standard rectangle, and multiple pieces can be pieced together to form a ring. This design is mainly aimed at better fitting the installation position of the motor rotor, making the fit between the magnet and the iron core tighter, while optimizing the magnetic field distribution inside the motor and reducing magnetic field fluctuations.

The illustration shows a neodymium wedge magnet, Most of them need to be made to measure.

In addition to neodymium material, wedge-shaped magnets can also be processed using materials such as ferrite and samarium cobalt, but over 95% of customers choose neodymium.

In permanent magnet motors, wedge-shaped magnets are widely used, especially in some motors that require high performance, such as servo motors, industrial motors, new energy vehicle drive motors, high-performance brushless motors, etc. Compared to ordinary rectangular magnets, wedge magnets can help improve the air gap magnetic density distribution, reduce cogging torque and vibration noise, and enhance the stability of motor operation.

Of course, the processing difficulty of a wedge-shaped magnet will also be higher than that of a regular magnet, as it involves multiple requirements such as dimensional accuracy and curvature, which can affect assembly if not processed properly.

If your company needs to buy this type of wedge-shaped magnet for motors, please provide us with magnet drawings to evaluate the price and delivery time.
