Corrosion-aware molded magnetic targets for resolver, encoder, and position feedback systems where coatings add process risk.
Coating-Free Resolver Magnet Targets is most relevant when best for sensor and drivetrain teams trying to avoid coating failure, edge chips, or glued target assemblies. Typical solution programs include Resolver targets, Absolute encoder magnets, and Position feedback discs, so the early review should confirm corrosion exposure, coating restriction, and resin barrier assumptions.
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 sensing-radius flux profile (Buyer-defined Bx, By, Bz, or angle output curve), because resolver and encoder magnets must be judged by the field at the sensor, not by the magnet part alone.
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 coating-free reliability target and magnetic pattern accepted without measurable criteria before moving from prototypes to repeat production.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Sensing-radius flux profile | Buyer-defined Bx, By, Bz, or angle output curve | Resolver and encoder magnets must be judged by the field at the sensor, not by the magnet part alone. |
| Coating-free reliability target | Humidity, salt, media, or sealed-housing condition by project | Removing coating only helps if the compound and assembly environment are matched. |
No. Coating-free designs still need material, resin, humidity, media exposure, and functional magnetic validation agreed during RFQ.
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.
