Lamination Stacks
Lamination stacks are packages using single laminations separated by electrical insulating layers to surpress eddy current losses during dynamic magnetic load.
VACOFLUX® X1
High performance combined with low weight is a key feature of motors built with this new low-cobalt-content alloy. Typically, motors can be realised that have a 20 to 30 % higher power density than with electrical steel.
9 to 27 % Cobalt-Iron
VACOFLUX grades with low cobalt content have been developed to offer an attractive price level for clearly defined applications.
