A successful story that bridges the past and future of mobility marks GROB Italy’s participation in the first edition of Coiltech North America, taking place on Wednesday 11 and Thursday 12 June 2025 at the Suburban Collection Showplace in Novi, Michigan, on the outskirts of Detroit.
In what was once the cradle of the American automotive industry, the Italian subsidiary of the global leader in the manufacturing of machine tools and automation systems will showcase technologies developed at its Pianezza facility, near Turin, dedicated to electric motor production lines.
Turin and Detroit, two iconic manufacturing cities, are once again intertwined — this time along the axis of sustainability — as they reinvent their industrial futures following the decline of traditional manufacturing. The setting is Coiltech, the leading exhibition for the Coil Winding sector, focused on technologies for the production of coils for motors and transformers. Since its first edition in Pordenone in 2010, this exemplary model of the Italian exhibition system has expanded to Germany and now North America.
GROB Italy debuts at Coiltech Novi backed by a proven track record that has made it a key reference partner in the international market. It provides comprehensive solutions for the entire electric motor manufacturing process. From feasibility studies to full project development, GROB experts assist companies in creating customized designs with varying levels of automation — from standalone machines to fully tailored production lines, covering all electrification sectors, including automotive.
«For GROB Italy, Coiltech Novi represents a prestigious international showcase — a chance to present our advanced technological solutions to a global audience,» says Maurizio Giammaria, Division Manager Electric Motors at GROB Italy. «The presence of Italian technology in such a competitive sector is a testament to our strength and innovation, proving that Italy can also excel in the high-tech industry.»
GROB Italy develops standalone machines that can be integrated with one another via workpiece transport systems or robotic automation cells. These systems are modular and flexible, allowing for high adaptability to diverse production needs. This setup optimizes workflow, reduces downtime, and ensures that each production phase can be handled independently without interruption.
Additionally, the ability to integrate various machines and systems enables the creation of customized solutions tailored to specific customer requirements, offering a clear competitive edge in the electrification sector.

Italian technologies serving sustainability
The expertise developed in Turin underpins the production lines for electric motors across a wide range of industries — from home automation to industrial applications.
GROB Italy designs and builds lines that accommodate multiple electric motor applications, delivering tailored solutions for any need.
Its technology supports distributed winding stators, coil insertion, and both segmented radial and axial flux motors. GROB also develops production lines for permanent magnet rotors and wound rotors, providing the flexibility needed to meet a variety of specifications.
GROB Italy stands out thanks to several innovative features:
- Patented antitwist technology for stator winding enables more copper to be inserted into the slots, significantly improving motor efficiency compared to competing solutions.
- In rotor production, minimal adhesive usage for fixing permanent magnets reduces manufacturing costs and enhances line flexibility for different rotor types.
- The magnetizer is positioned at the end of the process, allowing the use of non-magnetized magnets for improved cleanliness and reliability.
- Trickling impregnation technology enhances resin penetration into windings via capillarity, ensuring effective insulation.
GROB Italy also offers high customization options in terms of machine count and automation levels, making it suitable for a range of production volumes. Standard solutions can be modified and extended with additional processes to meet specific customer needs, delivering truly tailored manufacturing solutions.
Finally, Coiltech will also showcase other sustainable mobility technologies developed by GROB, such as fuel cell systems. The company is investing in this emerging field to meet growing demand for alternative and eco-friendly energy solutions. Fuel cells are becoming increasingly important in both the automotive and energy sectors, and GROB Italy is at the forefront of providing advanced manufacturing solutions for this evolving and competitive market.
