Ferrite Ring Magnet OD70xID32x15mm

Ferrite Ring Magnet OD70×ID32×15mm is a ceramic permanent magnet designed with a 70 mm outer diameter, 32 mm inner diameter, and 15 mm thickness for rotary magnetic field applications.
Manufactured from strontium ferrite through pressing and sintering processes, providing stable magnetic properties and corrosion resistance without additional coating.
The ring structure supports axial magnetization and can be mounted directly onto shafts or rotor assemblies for efficient magnetic field generation.

The Ferrite Ring Magnet OD70×ID32×15mm generates a continuous magnetic field around the ring structure, supporting stable magnetic flux output during rotor rotation in motors and generator assemblies.
The ring geometry helps distribute magnetic flux evenly across the magnetic circuit, reducing localized flux variation and contributing to more uniform torque generation during operation.
Manufactured from strontium ferrite with high coercivity, the magnet maintains magnetic field strength under repeated rotational cycles and normal motor operating conditions, helping reduce the risk of magnetic degradation over time.
The integrated ring structure provides concentric alignment with shafts and rotor components, supporting long-term operation in electric motors, generators, and other rotary magnetic systems.

We provide customized outer diameter, inner diameter, and thickness according to motor, generator, and magnetic coupling assembly requirements. Ring magnet dimensions can be adjusted to match shaft sizes, rotor structures, and installation constraints.

Axial magnetization, multi-pole magnetization, and customized pole arrangements are available based on magnetic circuit design requirements. Different magnetization patterns can be configured to support specific magnetic field distribution and motor operating conditions.

Production can be carried out according to customer drawings, technical specifications, or existing samples. Sample development, dimensional verification, and batch manufacturing are supported for both prototype projects and long-term production programs.

Ferrite ring magnets are commonly used in electric motors, generators, magnetic couplings, and rotary magnetic systems where a circular magnetic field is required around a shaft or rotor assembly.

What do OD70×ID32×15mm dimensions mean?

OD70 refers to the 70 mm outer diameter, ID32 refers to the 32 mm inner diameter, and 15 mm is the magnet thickness. These dimensions determine assembly fit, shaft compatibility, and magnetic circuit design.
