The success of the electric vehicle depends on two factors: range and performance. Carpenter Technology provides the advanced soft magnetic alloys and stack production capabilities required to build smaller, lighter, and more efficient traction motors. Our materials allow engineers to increase torque density and reduce core losses, directly extending battery life and driving consumer preference.

Enabled by high-saturation soft magnetic alloys.
Lower AC core losses for maximum battery efficiency.
From proprietary alloy melt to precision-bonded lamination stacks.
High-efficiency alloys that reduce energy waste through heat, allowing every kilowatt-hour of battery life to go further.
High-induction materials that enable higher torque at lower speeds, improving vehicle acceleration and towing capacity.
Superior magnetic properties allow for smaller motor footprints, reducing overall vehicle weight and increasing design flexibility.
Alloys with low coercive force that generate less internal heat, simplifying the cooling requirements of the electric powertrain.

The highest induction in the industry, allowing for smaller, more torque-dense electric motors.
Precision-rolled strip down to 0.05 mm to minimize eddy current losses at high frequencies.
Alloys optimized to withstand the high centrifugal stresses of high-RPM rotors.
roprietary insulation and bonding techniques that maximize stack integrity and electromagnetic performance.
We provide the "Magic in the Machine"—the materials that transform electricity into motion with minimal loss.
The traction motor is the most critical component of the EV powertrain. Our Hiperco® alloys allow for higher flux density, enabling motors that are lighter and more efficient than those using conventional silicon steel.
