an issue to OEM’s. • Particularly with the power & torque level delivered. • Economics are a challenge. • YASA clearly has a role in helping to solve those issues.
issues: • Maximise power delivered versus size of electric motor/generator • Cost per kW of generated power delivered • Motors for generating power • Motors for traction • Motors for auxiliary equipment and implements • For the tractor to implement initiative • For hybrid electric solutions • For full electric • Reduced emissions at a reduced operating cost
