Rotary Motors for Precision Positioning – What to Choose When?
shows the resulting torque/speed characteristics. Fig. 4 Torque/speed characteristic of a DC motor with idle speed, nominal operating point, starting torque, short-term, and long-term range. 2.2.1 Continuous [...] Output DC motors can provide the highest torque output at 0 rpm (standstill) while torque output drops to zero at their top rpm. Between these extremes, the torque/speed curve characterizes the performance [...] time constant of the winding, torque overload shown in multiples of the nominal torque. Higher loads result in increased motor losses due to the proportionality of torque and current, leading to higher
