Hi,
I am wanting to measure the torque produced by motor under a dynamic. The only constraints i have is that the power supply is DC, the motor needs to be able to supply around 1Nm of torque and i want to keep a reasonably constant speed of around 80-100 rpm...
I am current using a simple brushed dc 12v Drill motor fitted with a speed control. i am measuring the current and voltage and by calibration i have found a relationship between power and torque..
i have been told that a brush less DC could be better option as the speed can be controlled more accurately and torque computed more easily??
Or has anyone seen motor packages with a load cells fitted to the stators so that torque can be directly measured???
i am pretty new to all this sort of stuff so any help will be appreciated.. even if you could just point me towards some good shops or websites to check out.
i am purely looking for the simplest and most robust solution, cost is not too much of an issue.
Thanks, willy
