Does anyone know the top speed at 5v for the “DC 6V 100RPM 3mm Shaft Mini Metal Gearwheel Gear Motor N20 Geared Motor”
As far as I know, the no load speed is 30 RPM.
A motor’s output speed is proportional to the input voltage. Increasing the voltage causes the motor to operate at a higher speed. However, the motor’s speed will also be affected by the motor’s design and the load.
