LASER CUTTING

Latest generation fiber laser cutting system, 2 KW power, accuracy +/- 0.025 mm, 3000×1500 mm working table.

Ideal for prototyping, small series, special applications and service, fast manufacturing times, no investments in stamping tools.

Thanks to specialized partners we can offer single notching laminations, and/or made with combination laser cutting / single notching.

STACKING

Single laminations are stacked with special tooling, which is designed by our Technical Office with 3D software and manufactured specifically for each project, in order to guarantee the highest quality. Pressing is done by means of tie rods and springs or hydraulic presses, depending on the size and quantity.

WELDING

We are equipped with TIG and MIG welding for stator or rotor stacks.
We can perform soldering or brazing of aluminium or copper bars with end plates for rotor stacks.

BONDING

We use BACKLACK technology for stacks assembly. Each lamination is cut from a pre insulated sheet of electrical steel with a thermosetting polymer; when subjected to a temperature of about 200°C, the polymer reacts and allows their bonding.

If compared to welding or riveting, the advantages of this technology are the following:

No deformation in the stacks;
Better stiffness and stability of rotating stacks;
No vibrations in rotating stacks;
Improved accuracy in the alignment of laminations, improved squareness and flatness of stacks;
Absence of magnetic field disturbance caused by the welding.

TURNING

Turning is performed on request on the assembled stator and rotor stacks, in order to guarantee tight tolerances. Maximum diameter up to 2000 mm.

MACHINING

Mechanical machining is carried out on the assembled stacks.
The products that are usually machined are the following:

Stator stacks;
Stacks for linear motors;
Poles for AC and DC machines.

WINDINGS

Thanks to the cooperation with specialized partners, we can supply stators or single poles complete with windings.

ENGINEERING

We have a Technical Office with highly specialized staff and 3D software (Solid Edge) to design the stacking equipment and all the components that are made internally or in subcontracting.

We are able to carry out REVERSE ENGINEERING, issuing a technical drawing starting from a sample supplied by the customer. This activity is ideal in the case of SERVICE and REPAIR Companies.
