FROM PROTOTYPE TO SERIAL PRODUCTION

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.

Hiperco alloys also work as flux concentrators in electromagnetic pole pieces for different high flux applications, such as audio voice coils and medical radiology. These alloys are also used in actuators, specialty transformers, magnetic bearing applications.

Laminations

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.

We offer a full range of capabilities, including progressive stamping, compound stamping, notch stamping, laser cutting and EDM. With over a decade of sourcing, qualifying, and supplying laminations, we provide the market with over five million laminations per year. All products are managed per our Carpenter Technology quality control system to ensure best-in-class stack performance.
