China Neodymium And Ferrite Magnets Manufacturer & Supplier 
Multi-pole radial ring magnet is a permanent magnet in which multiple N and S poles are distributed circumferentially around a ring-shaped magnet and which is magnetised radially. It has become the mainstream choice for modern electric motors primarily because it provides a more uniform magnetic field distribution. Compared with traditional segmented, assembled magnets, multi-pole radial magnetisation ensures a more stable magnetic field within the motor, helping to improve operational efficiency and reduce torque fluctuations (torque ripple in segmented magnets typically ranges from 8% to 12%, whereas that in monolithic multi-pole ring magnets is only 3% to 5%), resulting in smoother and quieter motor operation.
The integrated ring structure also minimises assembly errors associated with joining multiple magnetic segments, making installation not only more convenient but also improving product consistency and reliability. Under high-speed rotation conditions, the monolithic ring magnet offers superior stability and is less prone to issues such as loosening or displacement of the magnets, making it particularly suitable for high-speed motors.

Multi-pole radial ring magnets also help motors achieve higher power density and a smaller footprint. For the same dimensions, they deliver superior electromagnetic performance, enabling motors to be lighter, smaller and more efficient; consequently, they are widely used in new energy vehicles, power tools, drones, fans, water pumps, robots and other fields.
As a specialist manufacturer of motor magnets, Carichi can customise multi-pole radial ring magnets to meet customer requirements in terms of size, material, number of poles and magnetisation method (internal or external).
