High-precision multi-pole magnet rotors for EPS (Electric Power Steering) and steering angle sensing.
Steering Angle Magnet Rotors is most relevant when best for steering system manufacturers needing high-pole-count rotors with strict dimensional and magnetic runout controls. Typical solution programs include EPS motor sensors, Steering angle sensors (SAS), and Torque and angle sensor modules, so the early review should confirm multi-pole magnetization accuracy and phase shift.
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 pitch error (Controlled to minimize angle calculation jitter), because in EPS systems, uneven magnetic poles cause steering feel issues and angle miscalculation.
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.
| Evaluation Metric | Typical Range | Buyer Relevance |
|---|---|---|
| Pole pitch error | Controlled to minimize angle calculation jitter | In EPS systems, uneven magnetic poles cause steering feel issues and angle miscalculation. |
| Validation handoff | Operating temperature, vibration, media exposure, and lifetime requirement | It connects Steering Angle Magnet Rotors design intent to sample approval, lot inspection, and production sourcing decisions. |
Yes, injection molding allows for thin-wall, large-diameter rings that would be too fragile if made from sintered magnets.
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.
