compacore® for the next level in electric motors

Manufactured using the premium electrical steel of voestalpine with a new, full-surface bonding process, compacore® lamination stacks guarantee improved electromagnetic and motor properties. Economical large-scale production is a further plus. compacore® full-faced bonded lamination stacks are the solution when high efficiency is in demand. Take advantage of improved design and layout to make the most of compacore® lamination stacks:

Higher efficiency

By reducing thermal loss caused by unwanted electromagnetic fields and vibrations, the motor's efficiency increases.

Better thermal management

The full-faced bonding ensures complete insulation and reduces interlaminar iron losses. It also provides best axial heat transfer. There is no metallic contact between the laminations, thus hot spots can be eliminated.

Increased vehicle range

Reduced iron losses ensure highest energy efficiency and increase the vehicle range for battery-powered mobile applications. 

Quieter motors

The full-faced bonding improves the vibration characteristics, resulting in a quieter moto.

Enhanced resilience

The bonded lamination stack forms a compact monoblock. This provides higher mechanical resilience during assembly and operation.

More design freedom

As a result of the full-faced bonding, there are no joining locations that need to be considered in the component design. Diameters can be reduced, resulting in increased design freedom.

Machinable

The stacks can be processed by mechanical machining. For example, rotors can be easily balanced in this way, making balancing discs obsolete.

Downsizing & weight reduction

Design freedom and machinability allow designers to eliminate components, reduce the dimensions and lower the weight of the motor.

Efficient serial production

The innovative baked self-bonding varnish and inline manufacturing ensure excellent reproducibility for small and large-scale production series.
