Vehicle technology supplier BorgWarner has developed its HVH250 electric motor and eGearDrive transmission for inclusion in the FUSO eCanter truck, the world’s first series-produced all-electric light-duty truck.
“For several years, BorgWarner’s engineers worked closely with FUSO on this milestone project,” said Dr Stefan Demmerle, president at BorgWarner PowerDrive Systems. “We are excited to offer our efficient, eco-friendly technologies as FUSO paves the way for powerful and sustainable commercial vehicle mobility.”
The Tier 1 supplier claims that the scalable HVH250 electric motors deliver industry-leading torque and power density. Instead of conventional round wire windings, BorgWarner’s HVH250 electric motor uses precision-formed rectangular wires and multiple layers of interlocking hairpins.
This patented high-voltage hairpin (HVH) technology enables the HVH250 motor to produce up to 425Nm of torque and 300kW of power at 700V.
With a compact, low-weight design and highly efficient gear train, BorgWarner’s eGearDrive transmission is designed to use less battery energy, therefore extending battery-powered driving range.
Additionally, as well as handling input speeds of up to 14,000rpm, the technology offers a range of gear reduction ratios for optimal acceleration for a variety of motor sizes.
