To make this measure more effective and tailored to the specific context of your company, we recommend that you first perform an overall analysis of your energy situation.

Replacing the hydraulic bending machine and press brake with a servo motor driven system

This measure aims to replace a hydraulic bending machine or press brake operating with a three-phase asynchronous motor, with equivalent technology equipped with a servo motor. The hydraulic system runs continuously, even when the machine is not producing, resulting in significant and unnecessary energy consumption.

Implementing this measure can reduce electricity consumption by more than 30%. It is quite easy to carry out and does not require production shutdown. Although the technology is highly mature, energy cost savings alone may not always be sufficient for a return on investment. However, the lower the machine’s operating frequency, the greater the potential for energy and financial savings. It is therefore recommended to prioritise retrofitting machines with short operating times maximise return on investment.

A servo motor is a motor capable of accurately controlling rotary motion and maintaining a precise position. It can be used to drive different types of pistons, such as hydraulic, spindle or rocker pistons, allowing the equipment’s start-up and operation to be precisely adjusted according to actual needs.

Miscellaneous savings

For the machine equipped with a servo motor, financial savings are mainly achieved through significantly reduced electricity consumption, up to 70% compared to the baseline levels

Apart from energy savings, a machine equipped with a servo motor offers several other advantages:

  • Precise movements and positioning
  • Lower maintenance needs thanks to optimised mechanics
  • Improved control over press speed and position

State subsidy application

State subsidies

Please note: any application for government or non-government subsidies must comply with the “incentive effect”, subject to compliance with the subsidy conditions.
To ensure that the incentive effect of the aid is respected, no binding commitments may be made (acceptance of a quote; advance)

N.B. While several state subsidies cannot be granted for the same project, they can be combined with supplier subsidies

Subsidies from electricity and natural gas suppliers

Since 2015, natural gas and electricity suppliers are required to make energy savings for consumers under the obligation scheme. Since then, energy suppliers have been offering support and advice, as well as subsidy programmes for consumers to implement energy efficiency measures.

The amount of the premium is proportional to the annual energy saving.

The following suppliers offer this service for companies:

N.B. Supplier subsidies can be combined with a state subsidy for the same project
