What Matters in EV Motor Rotor Magnet Design
EV motor magnet design starts with the magnetic circuit, rotor structure and operating conditions. We review these inputs for prototypes and production.
Temperature & Demagnetization
Grade selection accounts for magnet temperature, cooling, current loading and demagnetizing fields.
Rotor Fit & Tolerance
Drawing-based machining and inspection help control air gaps, placement and rotor assembly interfaces.
Coating & Corrosion Protection
Coatings are selected for humidity, fluids, corrosion exposure and the chosen assembly process.
Batch Consistency
Dimensional, magnetic and coating checks support prototype correlation and repeatable production.
