Motor drive

Direct drive for maximum efficiency

  • Direct power transmission

    Centrifugal fans with motor drive are characterized by their particularly efficient and space-saving design.

    In this design, the motor is connected directly to the impeller of the fan so that no additional transmission mechanisms such as belts or couplings are required. This direct power transmission minimizes losses and enables high energy efficiency at constant speeds. In addition, maintenance costs are significantly reduced as there are fewer wearing parts in the system.

    Whether for the ventilation of process air or the supply of fresh air in industrial plants - fans with motor drives are the ideal choice when a reliable and durable solution for consistent operating conditions is required.

  • Advantages of the motor drive
    • High energy efficiency
      Direct power transmission minimizes energy losses and reduces operating costs.
    • Low maintenance effort
      Without belts or clutches, there are fewer wearing parts, which simplifies maintenance and extends the service life.
    • Space-saving design
      The compact design enables flexible installations even where space is limited.
