Polar anisotropic ring magnets find a compelling application in power tools, primarily due to their ability to generate a high flux density despite their compact size. This characteristic makes them well-suited for power tool applications where space is limited. Unlike their radially oriented counterparts, polar anisotropic ring magnets exhibit a higher flux density, resulting in enhanced performance. Notably, the magnetic flux density on the outer diameter surface of these multipole ring magnets follows a sine wave pattern without the need for a magnetic shaft. This unique feature contributes to improved motor efficiency and reduced material weight, making them an advantageous choice for power tool design and manufacturing.
