Cobalt-iron material increases power density for motor applications

New Products |
Laminations made of cobalt-iron alloys are frequently used in aviation or motor sports as typically 20 to 30 % higher power densities can be achieved compared to electrical steel.

With its new CoFe alloy Vacoflux X1, Vacuumschmelze has succeeded in closing the existing gap between electrical steel and materials with a high cobalt content. The material can increase torque up to 12.5% compared to NO20 material, without rotor adaptation. The new material also supports increased efficiency, reducing copper losses by up to 28 %, according to a recent study cited by the manufacturer. This leads to an increase in the achievable range of the vehicle without having to increase the size of the battery.
