Descrizione del progetto
Nuovi motori sincroni per veicoli elettrici
I cambiamenti climatici hanno creato una maggiore necessità di innovazione in vari settori, compreso quello automobilistico. Molte aziende stanno cercando di soddisfare questa esigenza sviluppando e fabbricando automobili elettriche. Tuttavia, il processo di produzione rimane inefficiente e dannoso per l’ambiente. Il progetto HEFT, finanziato dall’UE, invertirà questa tendenza introducendo un rivoluzionario motore sincrono per automobili elettriche, che sarà riciclabile, efficiente in termini di costi e richiederà meno materiali, producendo meno emissioni e creando nuove economie circolari europee. HEFT è un progetto di ricerca che riunisce le competenze di università, centri di ricerca e aziende in materia di motori elettrici, materiali avanzati e circolarità, dalla ricerca di base allo sviluppo e alla sperimentazione di nuovi materiali e componenti.
Obiettivo
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.
