By taking advantage of its in-house capability for motors, inverters, gearing, clutches, thermal management, and software solutions, Dana said this is a true integrated system. The new e-transmissions, according to a news release, have “been engineered to provide the highest level of efficiency and performance with maximum startability, gradeability, and road speed.”
Key features include:
Dana high-efficiency motor and integrated inverter system, with silicon carbide technology and MOSFET (power modules, providing peak performance and simplified installation in the vehicle through the elimination of high-voltage phase cables.
An electromechanical actuation system, with patented Dana Graziano clutch design, to maximize shift smoothness and efficiency.
An optimized three-speed system with Ravigneaux gearing designed to seamlessly integrate Dana motor technology, offering maximum power density and productivity without compromise across a wide range of vehicles.
Dana OpenECU platform, leveraged across all Dana e-Propulsion technologies, to deliver next-generation control software, functional safety readiness up to ASIL C, and compliance with the latest vehicle cybersecurity engineering standards.
The Zero-6 currently holds six patents for advanced design, including a unique shifting method and arrangement, exclusive lubrication methods, and a design for manufacturability.
