GEM in-wheel Report Summary

Project ID: 691371

Periodic Reporting for period 1 - GEM in-wheel (GEM in-wheel motor)

Reporting period: 2015-12-01 to 2016-11-30

Summary of the context and overall objectives of the project

The electrification of traffic is one of the main strategic goals in the EU in terms of lowering pollution, noise and traffic emissions. EU citizens commute daily to work and other activities with an average distance of less than 15 km. Personal electric vehicles are the right solution for such daily transportation and significantly improve the quality of urban living. A two-passenger electric car can show an efficiency level around 10 times higher than one with an internal combustion engine, making the emerging class of Light Electric Vehicles (LEV) with three or four wheels increasingly attractive to a wider population. Dedicated propulsion solutions for LEV should satisfy the high requirements regarding quality, performance and safety.

The project GEM in-wheel, which is carried out within the Fast Track to Innovation Program of the European Commission, pursues the industrialization of GEM motors' in-wheel technology. The GEM in-wheel motors are designed for LEV with a disruptive high-performance multiphase architecture and safe low-voltage operation. The project includes the product diversification towards a range of 2 kW to 6 kW. Moreover, the production technology is developed and optimized for cost-efficient production. A thorough market research and product commercialization strategy are prepared to facilitate an efficient market entry of the technology.

Work performed from the beginning of the project to the end of the period covered by the report and main results achieved so far

In the first 12 months of the project, two iterative product development steps were carried out with a prototype series production, a re-design step and the start of the pre-series production. In a parallel action, the supply chain was set up with the manufacturing of all major parts and the pilot assembly line ready for pre-series production 11 months after the project start.
Extensive measures for the preparation of commercialization were implemented with a thorough market research, exhibition on relevant trade fairs as well as presentations and publications on several international conferences.

Progress beyond the state of the art and expected potential impact (including the socio-economic impact and the wider societal implications of the project so far)

The GEM in-wheel motor technology represents a disruptive approach for the propulsion of Light Electric Vehicles. The steps carried out towards a successful industrialization and commercialization comprise iterative production development steps. The currently produced pre-series meets customer needs and is integrated in several OEMs' vehicle development plans, thus facilitating the launch of highly-efficient means of transportation.
