Slide 4: Seamlessly maintaining higher torque density throughout vehicle operation leads to significant cost savings
Coil Driver is an adaptive electric vehicle traction inverter In essence, the Coil Driver automatically selects between that replaces the standard inverter in electric vehicles. The two modes in a single motor, minimizing the tradeoff faced in patented Coil Driver technology applies coil switching t
Slide 5: Background: recycling of vehicle materials
BACKGROUND For combustion cars, the bulk of vehicle mass is steel and aluminum. Recycling rate for steel and aluminum in the automotive sector exceeds 90%. 10% new material This is because steel, copper and aluminum remain as metal during the recycling process, saving of the energy required to produ
Slide 6: Background: new metals in batteries and magnets are hard to recycle
BACKGROUND As we move toward electrification with the aim to eliminate CO2 emissions, we are adding new metals into the transportation eco system: in the batteries. in the magnets used in the motors. The challenge with these new materials is that they are not very easy to recycle. This is primarily
Slide 7: We don't need to, and arguably shouldn't use neodymium
Copper and iron are metals that can be produced with zero carbon, are infinitely reusable and the only two materials we need to build great electric machines. We don’t need to, and arguably shouldn’t use neodymium. The content of this presentation is proprietary and confidential information of Exro
