Aeroperm - Stator Cores
REDUCE CORE LOSSES BY UP TO 97% WITH AEROPERM
ELECTRIC STEEL
AEROPERM
MORE WORK. LESS HEAT.
Aeroperm® is a 2.0 T nanocrystalline stator core material designed to reduce the losses that limit high performance electric motors. The simulations above show how replacing conventional iron silicon steel with Aeroperm® can lower heat generation inside the motor, improving efficiency without increasing motor size. For vehicle and UAV platforms, this creates more usable energy for range, endurance, payload and system level cost reduction.
MATERIAL PROPERTIES
Aeroperm® stator cores combine high magnetic saturation with low core loss, giving motor designers a larger efficiency envelope without sacrificing magnetic performance.Compared with conventional electric steel and other high saturation soft magnetic materials, Aeroperm® maintains 2.0 T magnetic polarisation while significantly reducing losses. For stator core applications, this means more usable power, less waste heat and greater design freedom for compact, high-efficiency electric motors.
ENGINEERED FOR HIGH-EFFICIENCY STATOR CORES
Aeroperm® is designed to give motor engineers the magnetic performance of conventional non-oriented electric steel with substantially lower core losses.
With a 2.0 T saturation magnetic polarisation, Aeroperm® maintains the high flux capability required for compact, high-power-density electric machines. Its 0.024 mm lamination thickness helps reduce frequency-dependent losses, making it especially valuable in high-speed, high-efficiency, and thermally constrained motor designs.
For automotive powertrains, this supports improved drive-cycle efficiency, lower heat generation, and reduced cooling demand. For UAV and advanced electric propulsion systems, the same material advantage can be used to increase endurance, payload capacity or onboard power availability.
DIRECT REPLACEMENT OR CLEAN SHEET DESIGN
The contour plots below compare a simulated EV traction motor with its original electric steel stator core and with Aeroperm® used as a direct replacement. The blue points show WLTP3 drive cycle operating conditions. In this simulation, Aeroperm® reduced WLTP3 drive cycle energy consumption by 3.5%, with >10% gains estimated when the motor and drivetrain are optimised around the material.
