Multi-Pole Magnetization

Magnetization planning for multi-pole rings, sensor rotors, encoded magnets, and custom magnetic field profiles.

Best Fit For:Best for engineering teams where magnetic field shape is the product function, not just a material property.

Capability Highlights

Radial, diametrical, axial, and multi-pole pattern review
Fixture and inspection approach tied to the final sensor or motor function
Magnetic acceptance criteria defined before sample release

Typical Engagement Scope

Sensor rotors
Stepper motor magnet rings
Encoder magnets
Valve motor rotors

Execution Focus

Pole count, sensing radius, phase alignment, and reference marks
Flux mapping, gauss inspection, and functional test strategy
Magnetization fixture feasibility for molded geometry

Program Evaluation Matrix

Program Metric	Typical Range	Procurement Value
Pole-to-datum alignment	Project-defined reference angle or mechanical key	Assembly teams need the magnetic pattern aligned with a physical datum to avoid calibration drift.

RFQ Preparation Checklist

2D/3D drawing, material target, magnetic pattern, and sensing datum
Operating temperature, vibration, media exposure, and lifetime requirement
Sample quantity, tooling target, annual forecast, destination, and PPAP needs
Pole count, magnetization direction, reference angle, and flux inspection method

Risk and Mitigation

Brittle sintered magnet carried into a vibration-critical assembly: Review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety.
Magnetic pattern accepted without measurable criteria: Define flux density, pole count, angle error, sensing radius, concentricity, and inspection method before sample tooling.

Buyer FAQ

Do you need a magnetic map for quotation?

A full map is helpful but not always required. At minimum, provide pole count, magnetization direction, sensor air gap, and any curve or angle-error target.
