We will be on holiday from 24th December 2016 to the 2nd January 2017.
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.
Please visit us at Coiltech 2016 in Pordenone! We will be pleased to meet you!
Coiltech is an international exhibition dedicated to the Coil&Winding industry. There you will discover the last trends about materials and machineries for the production of electric motors, generators, transformers and winding systems.
Fix an appointment if you need much time with us to speak about a project or simply come there to ask us about our last developments. Single poles selection and assembling, magnets insertion, Backlack automation and new control lines are just a few of the new tendancies that Dema has recently made for its Customers.
Dema stand is Nr B12 in the Hall Nr 9 (just in front of the main entrance). For any further information, please contact us at email@example.com or call us!
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
Be in touch with the future….contact Dema!!!
Dema now can propose to its customers many solutions to assemble the armature.
The classic solutions are:
Both machines can use loose laminations or interlocked stacks.
Recently Dema developed some new stand-alone machines able to assemble end fibers and commutator, that can be integrated downstream the Basic Armature Machine and complete the armature production process:
By today you have the opportunity to improve your armature production process step by step, choosing which production steps you want to make more reliable.
Please contact Dema if you improve your armature production process!!!
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!
Like every year, Dema is waiting for you at the CWIEME Fair in Berlin, the World’s largest international coil winding, insulation and electrical manufacturing exhibition. This is a fix appointment for Dema and also this year from 10th to 12th of May we will be pleased to meet you in our stand.
Our stand is situated in the upper Hall 3.2 and the stand number is D32C39.

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.
Dema wishes to all its Customers and Contacts a MERRY CHRISTMAS and a HAPPY NEW YEAR 2016.
Concerning the optimal exploitation of the material, the sheet metal cost imposes to minimize blanking scraps; this has led to the development of the tendency of producing the stator by assembling its small-size portions, purposely drawn from sheet metal zones otherwise eliminated as scrap. The single poles of a stator lamination are then blanked one by one, to be first assembled in stator poles, called “T Poles”, and successively, assembled to form the stator in its definitive geometry.
Talking about the drastic reduction of the productive process cost, linked with the capability of automating the process itself, it is necessary to take into account that the productive process of “Backlack” stacks needs several stages: handling of single laminations, assembly of stacks , loading and unloading of the equipment used in the thermal cycle, thermal cycle, machining of the produced stacks and final packaging. Hence the choice of the opportune automation is influenced by countless factors.To realize the production cycle, loose lamination stacks must be placed inside proper equipments, to be designed case by case, which, besides determining the quality of the produced stacks , at the same time establish the quantity of used energy. Finally, the choice of the heating and cooling process depends on the choice of the automation degree of the productive process in its whole, which in its turn influences the definition of the necessary equipment.
