Discover the advantages of Polar-Anisotropic Ring Magnets, a powerful counterpart to radially magnetized ring magnets. Learn how their higher magnetic flux density makes them an ideal choice for enhancing the performance of brushless DC motors.
The Polar-Anisotropic ring magnet is a type of multipole ring magnet that, when compared to radial-anisotropic ring magnets with the same material grade and size, demonstrates a higher magnetic flux density. This key advantage has led motor designers to increasingly opt for this innovative multipole ring magnet over its radially magnetized counterpart in various applications.
The orientation of this type of multipole ring magnet is similar to the arrangement found in a Halbach array, which is why it is also referred to as a “Halbach multipole ring magnet”. This arrangement leads to an enhancement of magnetic flux density (field strength) on one side of the magnet. As a result, its field strength surpasses that of an identical radial-anisotropic (radially magnetized) ring magnet.
