BorgWarner’s electric motor and eGearDrive transmission propel all-electric Fuso eCanter trucks
BorgWarner announced that it supplied its HVH250 electric motor and eGearDrive transmission for the initial launch of the Fuso eCanter truck, what is considered to be the world’s first series-produced all-electric light-duty truck. According to Fuso, more than 200 third-generation units are being tested in urban areas. BorgWarner’s scalable HVH250 electric motors are designed to deliver industry-leading torque and power density. With a compact, low-weight design and efficient gear train, BorgWarner’s eGearDrive transmission is intended to use less battery energy, extending battery-powered driving range.
“For several years, BorgWarner’s engineers worked closely with Fuso on this milestone project,” said Dr. Stefan Demmerle, President and General Manager, 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.”
Instead of conventional round wire windings, the HVH250 electric motor uses rectangular wires and multiple layers of interlocking “hairpins.” This patented high-voltage hairpin (HVH) technology enables the HVH250 motor to produce up to 425 N·m of torque and 300 kW of power at 700 V. Featuring a compact design for easy integration, the HVH250 electric motor reportedly delivers efficiency of over 95% and provides better continuous power compared with competitive models. BorgWarner’s family of HVH electric motors is designed for flexibility, offering scalable torque and output for a range of light- to heavy-duty applications.
The eGearDrive transmission’s compact, low-weight design and efficient gear train reportedly achieves high-torque capacity yet uses less battery energy. In addition to handling high input speeds of up to 14,000 rpm, the technology offers a range of gear reduction ratios for optimal acceleration for a variety of motor sizes. An optional electronically actuated park lock system is available. Approximately 99% of the materials used in the eGearDrive transmission are recyclable.
