Multipole Ring Technology

Multipole Rings can be sintered into a truly radial geometry by using a special technology. This replaces the costly and labor-intensive method of gluing arcs, bread loaves, or rectangular segments onto a rotor shaft.

This new technology improves the uniformity of magnetic flux, which increases motor efficiency and torque. Other benefits include ease of assembly, superior mechanical properties, better magnetic qualities, and elimination of the re-work associated with chipped discrete magnets.

These multipole rings are revolutionizing the permanent magnet space for synchronous motors, stepping motors and DC brushless motors widely used in automotive, computers, electronics, etc.
