Measurement of gear DC motor characteristics
· You could also connect a winch to the motor shaft and put a weight on a string and have the motor winch that up. The amount a torque involved is an easy calculation and the current can be measured. You need to take care though that the string cannot coil up on itself. The diameter needs to remain constant. Measure the current when the motor is more or less at constant speed and use a .
