Servo Motor Maximum Load Torque Testing ,25kg.cm 

I am just learning about servos after a few minutes of googling I think there are some things wrong with this test. The distance the weight is attached on the servo arm matters. At 1cm it might be able to lift 20kg, but at 2cm it would then be 10kg. Also, the torque rating is a stall torque. So the servo can't lift that much weight if you help the weight a few inches off the ground, the servo could keep hold it there.

It's 25 kg-cm of torque. Looking at the bracket on Amazon, the load is no less than 30 mm or 3 cm from the servo pivot point. Max torque occurs when arm is perpendicular to the ground. The 3kg load requires 9 kg-cm to lift and the 5 kg load requires 15 kg-cm. Of course the arm starts out at about 30 degrees from the perpendicular so reduce your available torque by cos(30)=0.866 or by about 15% (1.0-0.866). Hence the 5 kg load now takes over 17 kg-cm to get moving. Of course as someone else pointed out these motors are always OVER-rated by the manufacturer as they quote STALL torque and not RATED torque.Odds are good the servo rated torque is about 1/3rd of the 25 kg or about 9 kg-cm. So now we see why the 3 kg load worked like a charm, the 5 kg not so much.

You must take into account the distance from the pinion to the arm that supports the load, if for example it is 5cm, it would be 25kg*cm/ 5cm, that is to say it would support just the 5kg, in addition your power supply must be good and deliver enough current... Excellent video editing, I loved it

Nice demo. I had no idea a 25kg servo could move so much weight.

20kh meaning nearest to shaft 20kg when it increase the distance potential reduces

Que amperaje requiere ese servomotor para funcionar a su capacidad media?

Hello nice job, this a digital or analog servo ?

This music ia destroying my soul

Awesome demo

Guys I need an urgent answer Does it get the command and the power directly from the arduino with no driver in between????!

What is the working voltage and current required to run this high torque servo motor?

Hold?

i tried working with a 15kg-cm torgue servo and cant lift a 1.5kg cantilever beam at all.. am i doing somethign wrong is it how it is? i would love to know the answer

Mg 995 servo motor needs voltage supply from 4.8 to 7.2 volts, Can I use two 18650 li batteries which give 7.6 volts?

Nice video. Please I want to control about 10 servos, of this kind, I also want to send commands from the arduino board, how do I go about it?

How many kg can that servo lift using pulleys?

Please make vid test servo using external power for more ampere

Does this use the same arduino code as the tower pro servo?

This test is not adequate. You cannot draw enough power from the arduino 5V to power this servo fully, an arduino uno can suply about 500ma at 5v, which is probably 30% of the amperage required. You must also take in to account the lever arm length. 25kg-cm is equivalent to 12.5kg-2cm.

Kodingnya dong

is the the connection only from the arduino? It's working only on 5volts....
