Eliminating Mechanical Parasites: Achieving Over 95% System Efficiency Through Streamlined Drive Assemblies

An e-axle does not lose efficiency in one dramatic event. Energy is consumed through gear mesh, bearing drag, seal friction, oil churning, rotor losses, inverter switching, and thermal-management demand. These “mechanical parasites” become especially important at light load, where fixed losses represent a larger share of the input power. Achieving more than 95% system […]
