May your Christmas be an opportunity to stay with your loved ones, experiencing moments full of Serenity.

Dema Staff wishes you a Happy Christmas and a 2018 full of satisfaction.

Our offices will be closed from 23rd December 2017 to 7th January 2018. 


As a prompt answer to the growing relationships and cooperation in the USA, Dema decided to take part at the CWIEME in Chicago from 4th to 6th October.

We are really pleased to meet our American Customers, but also our  international contacts and new ones. So please come to our booth to have a look at our last technology evolutions.

We will be at your disposal at Stand F13 in the Hall A.


How is changing the manufacturing pro­cess of electric motors?

Dema is developing the answers to that question concerning the ambit of the rotor and stator laminations and stack handling.

Dema is currently developing research & development projects in 3 areas:

Loose laminations handling to move them from the blanking press

Full automatic Backlack production lines to produce Backlack rotors, stators and single poles

High speed control process to check interlocked stacks directly downstream of the blanking press

Any smart invention can be improved: Dema presents the Electric “ShaftCut” Machine

The notching process is one of the cheapest methods to grant the interference between shaft and lamination stack and / or shaft  and commutator. Dema has designed and developed a machine whose name is “E-ShaftCut” that could be stand-alone or integrated in line. This machine is a full automatic station for cutting rotor shafts by an electric press.

The main purpose is to guaranty a high repeatability of shaft / lamination stack and of shaft / commutator coupling process.

The use of the electric press increases the process stability; when the coupling changes due to the components tolerance variations the machine reacts automatically.

This big advantage has to be added to the other advantages of the basic hydraulic machine: cheaper shaft cost and reduction of the scrap armatures produced.

The final result on using the E-ShaftCut Machine is to guaranty process quality, high reliability and easy configuration and setting.

Please, ask us more about “E-ShaftCut” Machine!


Dema is carrying on a european project of R&D. The project name is Spark, programm Horizon 2020.

Horizon 2020 has the political backing of Europe’s leaders and the Members of the European Parliament. They agreed that research is an investment in our future and so put it at the heart of the EU’s blueprint for smart, sustainable and inclusive growth and jobs.By coupling research and innovation, Horizon 2020 is helping to achieve this with its emphasis on excellent science, industrial leadership and tackling societal challenges. The goal is to ensure Europe produces world-class science, removes barriers to innovation and makes it easier for the public and private sectors to work together in delivering innovation. Horizon 2020 is open to everyone, with a simple structure that reduces red tape and time so participants can focus on what is really important. This approach makes sure new projects get off the ground quickly – and achieve results faster. The EU Framework Programme for Research and Innovation will be complemented by further measures to complete and further develop the European Research Area. These measures will aim at breaking down barriers to create a genuine single market for knowledge, research and innovation.

Dema is focused on development of technologies needed for the use of Backlack laminations: Backlack, T-poles (automatic production), bonding process, specific tools, T-poles winding, stacks final assembling, post processing activities and quality control. The phase 1 of the project is already achieved, so Dema is now already working on phase 2.
