Summary--The main problem in the design of an incremental motion system is the heating of the motor which results from the start/stop type of operation. The question answered in this paper is how to select the components for this system and how to use them in order to minimize the operating temperature of the motor. In the analysis of the control selection, the optimal control was determined which minimizes the energy dissipation. It is shown how a triangular velocity profile, obtained using Bang-Bang control, corresponds to an efficiency of 0.75, whereas a slight change to trapezoidal velocity, increases the efficiency to 0.89 when compared with the optimal control. The optimal gear ratio will differ from the "inertial match" due to the presence of constant load torque. For a capstan drive, the inertia of the capstan must be much smaller than that of the motor, and not "inertially matched".
