With motor voltages in many e-mobility applications effectively doubling from the 400V region to 800V or more, one of the issues that arises is preventing breakdown of the insulation within the motor slots, the key stressor being partial discharges. Italian insulation specialist Coveme has developed processing improvements to DuPont Nomex dielectric material capable of withstanding such discharges – improvements that allow the material to be applied at scale by existing production machinery. The company has also launched a new humidity resistant Nomex material for battery cell and module spacers, writes Peter Donaldson. Read more…
