Sounds like a daft method if you ask me - unless your motor is very low
rpm.
is daft but cheaper, I have no money to buy a dynamometer
You do not need to buy a dynamometer...
Just mount the motor so that the casing can rotate a bit. Fix an arm on the
mount that sticks out to one side, hang weights or a spring on it. Torque =
force (in Newtons) x distance (in meters).
