One-stop-shop for laminations and stacks

We’re here to support your stator and rotor stack needs, from prototype to serial production. Our range of lamination, heat treatment, bonding, and assembly techniques are optimized for quality and process yields for scalability. Our team implements the best production method for your product given the unique performance requirements, design maturity, and volume demands based upon our expansive process datasets and experience.

Stator and Rotor Stacks

Iron cobalt alloy stacks require specific knowledge about materials and stack processing technologies to create high-quality best-in-class stator and rotor stack responses. Improper processing can significantly compromise performance.

Carpenter Technology’s expertise in specialized materials and stack processing ensures the highest performance stator and rotor stacks for our customers. Our engineers have a deep understanding of metallurgical structure-magnetic property relationships and expertise in various processing technologies. Without expert processing, iron cobalt stator and rotor stacks will perform only marginally better than standard electrical steel. Our Hiperco® alloys and stack manufacturing methods for dimensional control, high-strength, and tailored magnetic properties support the most demanding motor design requirements and production tolerances, ultimately resulting in superior motor responses.

From tooling and stamping to annealing, insulation, bonding, and quality testing, Carpenter Electrification offers a simplified supply chain and short lead times for prototypes and mass production.

FEATURES
