Magnetization planning for multi-pole rings, sensor rotors, encoded magnets, and custom magnetic field profiles.
Multi-Pole Magnetization is most relevant when best for engineering teams where magnetic field shape is the product function, not just a material property. Typical oem capability programs include Sensor rotors, Stepper motor magnet rings, and Encoder magnets, so the early review should confirm pole count, sensing radius, phase alignment, and reference marks.
Before sample tooling, align on 2D/3D drawing, material target, magnetic pattern, and sensing datum and operating temperature, vibration, media exposure, and lifetime requirement. The first acceptance check is pole-to-datum alignment (Project-defined reference angle or mechanical key), because assembly teams need the magnetic pattern aligned with a physical datum to avoid calibration drift.
The main risk is brittle sintered magnet carried into a vibration-critical assembly; control it by review bonded magnet material and molded geometry when chipping, cracking, or adhesive failure can affect functional safety. Also review validation handoff and magnetic pattern accepted without measurable criteria before moving from prototypes to repeat production.
| 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. |
| Validation handoff | Operating temperature, vibration, media exposure, and lifetime requirement | It connects Multi-Pole Magnetization design intent to sample approval, lot inspection, and production sourcing decisions. |
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.
Include 2D/3D drawing, material target, magnetic pattern, and sensing datum, operating temperature, vibration, media exposure, and lifetime requirement, and sample quantity, tooling target, annual forecast, destination, and PPAP needs. If the part is tied to automotive or safety-critical sensing, also include PPAP, traceability, and magnetic test expectations.
