Presets
A DC motor speeds up until back-EMF balances the applied voltage, giving a first-order step response. Its steady speed drops linearly with load along the speed-torque line: maximum speed at no load, maximum (stall) torque at zero speed. The green dot is the operating point where motor and load torque match.
Data Inspector
No-load speed240 rad/s
Steady speed224 rad/s
Stall torque0.30 N·m
Current draw0.4 A
Reading this result: Light load: speed stays close to the no-load value, since only a small back-EMF drop is needed to supply the torque.
