Production/Industrialization
Materials & Processes
Form Litz Winding (copper winding technology)
Patented winding technology for traction motors with copper fill density up to 65%, reduces e-motor losses by up to 25% and can be produced on existing hairpin winding lines.
Copper
Material for windings (Form Litz Wire, hairpin) in electric traction motors.
Iron
Material for stator and rotor designs; material usage is reduced by the winding technology.
Rare earth metals
Used in permanent magnet synchronous motors (PSM); quantity used is reduced by the design.
Power semiconductors (IGBT, SiC, GaN)
Compatible semiconductor technologies for the 3-level 800-volt inverter topology of the HV Multi-Level Inverter.
