with the scalability to move from a semi manual to a fully automated process. This versatility offers customers benefits including the opportunity to work with one partner for all their e-manufacturing needs. is aimed at meeting current and future production scenarios, and can address customers’ “pain points”. Other benefits include the optimised footprint and lean production set-up, real-time process monitoring for enhanced quality assurance, and reduced operational and energy costs. The stator assembly modules were engineered within the company’s centre of excellence of e-motor technology in Shanghai, China, with the key operation stations of wire forming, insertion, widening, twisting, cutting and welding produced in-house by Comau China. The company’s strategy of having a global presence with local roots complements China’s growing e-drive trend while also allowing Comau to quickly respond to worldwide market demand. With its R&D, prototyping, mass production and engineering expertise, Comau can provide tailored solutions to electric vehicle and motor manufacturers on a global scale. Comau’s engineering approach

Comau has launched a hairpin stator technology portfolio covering the entire stator manufacturing process, from hairpin wire forming, insertion to wire widening, twisting, and from laser welding to quality testing and control checks. The expanded offering reinforces the company’s ability to provide turnkey solutions for the entire motor assembly process, from design to execution. It also reflects Comau’s engineering and electrification competencies, having delivered a functional and validated solution within years of developing the initial prototype line. Stators are critical structural and functional elements within electric motors. Their production is a complex process that requires high precision and control levels. stator assembly line is designed to ensure efficient, flexible and accurate end-to end manufacturing of hairpin stators Comau’s fully configurable

This includes batteries in addition to e-motors and e-vehicle assembly solutions. The launch of its proprietary hairpin assembly technology is aimed at helping customers to improve the efficiency and flexibility of their production environment. Comau’s competence spans each stage of the assembly process, from the initial design and integration to optimisation strategies and the delivery of flexible and scalable turnkey production systems. “The newest solution within our robust e-mobility offer meets the growing demand for hairpin stators by automakers around the world,” said Comau CEO Pietro Gorlier. “It also complements our ability to design and implement value-driven electrification solutions that increase manufacturing efficiencies while ensuring the high level of quality and excellence Comau is known for.
