An improved motor control for banknote handling apparatus is described. An improved stacker pusher motor arrangement has a defined cycle of operation. The time it takes the stacker pusher motor to complete a predetermined portion of this cycle is measured. A braking time is computed from the measured time, and a braking control signal dependent thereon is applied to the stacker pusher motor to stop the stacker pusher motor at the appropriate position. An improved banknote transporting arrangement measures the time needed for a banknote to travel from a first point to a second point. A braking time is computed from the measured time and an appropriate braking control signal is applied to stop the banknote at the appropriate position.
