Internal ribs partition the cooling passage in an electric machine case, improving rigidity while simplifying manufacturing core splitting.
Sealing plugs block hot air recirculation and water ingress to prevent screw corrosion in motor vehicle rotating electrical machines.
Insulated copper bars replace bulky cables in radial feedthroughs, enabling high power capacity and safe rapid depressurization.
Segmented engagement parts on the motor main body and casing enable quick fan motor repositioning to mitigate resonance without complex assembly.
