Performance Overview


Options such as slip rings, surge arrestors, exciter housings, induction-free starting resistance and segment stator are available, depending on the location-specific requirements.

Advantages of brushless excitation systems

  • No pollution

    The brushless excitation system does not create any carbon dust pollution.

  • Short downtimes

    The result reduces maintenance expenditure and shortens downtimes.

  • Lower costs

    Reduced costs for spare parts.
