Novel concept of a low cost, high power density and highly efficient recyclable motor for next generation mass produced electric vehicles

Descripción del proyecto

Nuevos motores síncronos para vehículos eléctricos

El cambio climático ha espoleado la necesidad de una mayor innovación en diferentes sectores como, por ejemplo, el sector automovilístico. Muchas empresas bregan por satisfacer esta necesidad mediante el desarrollo y la producción de automóviles eléctricos. Sin embargo, el proceso de producción sigue siendo ineficiente y perjudicial para el medio ambiente. En el proyecto HEFT, financiado con fondos europeos, se invertirá esta tendencia mediante la introducción de un motor síncrono revolucionario para coches eléctricos, que será reciclable, rentable y requerirá menos materiales, al mismo tiempo que generará menos emisiones y creará nuevas economías circulares europeas. HEFT es un proyecto de investigación que reúne los conocimientos especializados de universidades, centros de investigación y empresas en materia de motores eléctricos, materiales avanzados y circularidad, desde la investigación básica hasta el desarrollo y ensayo de nuevos materiales y componentes.

Objetivo

HEFT considers that an energy efficient rare-earth synchronous motor is the best option for next generation high-power primary axle traction EVs and proposes a set of innovation challenges on electric synchronous motor configuration based on SiC inverters (direct cooling of rotor and stator, advance insulation for high voltage, multibarrier rotor topology, wave windings) and advanced materials (advanced GBD magnets, epoxy for magnet fixation, composite for motor housing, insulation resin).
These innovations will result in a high-efficient and low-cost solution that will be validated on 2 motor topologies, which compared to two main reference automotive IPM commercial motors in Europe (VW ID.3 and FIAT500) will lead to next impacts: >800V, 20% reduction losses, >7 KW/kg and 42kW/l power density, 28% cheaper, 50-66% material savings, including 60% reduction of REE content and >80% REE recyclability rate.
As this solution is still dependent on REE from China, HEFT will be aligned with the ERMA action plan towards a circular economy market of rare earth permanent magnets and suggests: one alternative magnet route (Ce based) and two REE recycled routes together with policies promotion towards the foundation of a European rare earths industry, capable of delivering 20% of EU demand by 2030.
HEFT plans 8 WPs to implement these concepts, where 5 research partners will be essential for developing innovative ideas around the design-to-x approach, while strong companies (GKN, MAGNETI, VYNCOLIT) will ensure that HEFT results have a clear market orientation and fulfil the industry needs.
HEFT plans to organise OEM workshops to ensure wide adoption of HEFT solutions, but also with policymakers to promote regulations towards the EU circular market that would help maintaining the leadership of EU companies, while increasing their competitiveness and job opportunities linked to the new circular business models.
