Power flow Power flow Force flow describes the path mechanical energy takes within a technical system. describes the path mechanical forces take within a technical system, particularly from the drive to the point of action — where the force is ultimately used. Typically, the force flow runs through several machine elements, such as motors, couplings, gearboxes, shafts, and bearings, before reaching the output. In gearboxes or drive trains, the power flow can branch, change direction, or redirect via gear pairs, reversing gears, or planetary stages. Analyzing the power flow is essential for designing, sizing, and assessing the efficiency of technical systems.
