Typically, the arm and the sun gear will each be driven in some direction at some velocity. In many cases, one of these inputs will be zero velocity, i.e., a brake applied to either the arm or the sun, (sun gear/planet gear and planet gear/ring gear) because one gear is used in both gear pairs—the planet gear. For Concepts B and C the center distances of both gear pairs must be equal, thus enabling both planet gears to be connected to one stepped planet gear ….
