Trinity of Power - COBALT-IRON SOLUTIONS FOR HIGH-PERFORMANCE MOTORS

COBALT-IRON LAMINATION STACKS TO IMPROVE ELECTRIC MOTOR PERFORMANCE

AS A FULL-RANGE SUPPLIER of magnetic solutions, VAC combines material knowledge with manufacturing expertise. Our vertical integration enables precise harmonization of every individual step of the process. The advantages are obvious: Since VAC controls every step from material production and manufacturing of parts to the assembly of complete components such as rotors or stators, individual customer requirements are taken into account in every step of the process.


OUR CUSTOMERS' ADVANTAGE:
Customers enjoy a comprehensive network of support from material science through process, to final stator and rotor assembly. A customer tailored focus to maximize performance, reduce cost and scrap, in a holistic supplier-partner relationship.

Benefits

  • Very high saturation polarization of 2.3 T
  • Low coercivity down to 35 A/m (VACOFLUX 48)
  • Very high yield strength up to 800 MPa (VACODUR S Plus)
