Multipole ring magnets feature precisely distributed alternating magnetic poles along their circumference. As a type of annular magnet widely used in electric motor applications, they are specifically designed for modern motors pursuing high efficiency, precision, and power density - such as Brushless DC Motors (BLDC) and Permanent Magnet Synchronous Motors (PMSM) – as well as high-resolution rotational position/speed sensors. They have become the preferred choice for servo motors in power tools, Electric Power Steering (EPS) systems, and other advanced motion-control applications.
