Correct me if I'm wrong but I believe they are functioning as intended as they have a specification of 13kgcm at 4.8v and 15kgcm at 6v, and in the video, and I see that the 4kg load is suspended quite far from the actual servo. For example, if you were trying to lift a 2kg weights suspended from a distance of 10cm from the servo head, the servo would have a torque of 1.3kg at 4.8v and 1.5kg at 6v whilst lifting the suspended weights, so it would not be able to pull the servo
No they don't ! As you can see, they do not support 4kg , and can't put that load up. The load is suspended at 1 cm only from the center of rotation of the servo.
@@obordes I see, my bad, but I'm curious as to how the distance the weights are suspended would impact the torque of the servo or if it wouldn't make a difference
@@arhamthowheed9471 The more the weight is far from the rotation point, the less weight can be carried... Torque= Force * Distance, so if you increase distance, Force must be reduced to keep the same torque.
the servo receives a pwm (pulse width modulation system) and works against the load to try and keep it's position. the heavier the load, the harder the motor has to work and the more force is applied on the gears. they keep moving a tiny bit to correct the position. That is what makes the noise, it is normal for servos, it's how they work. Want less noise? buy bldc actuators with decoder, they only cost 30 times more! 🤣
@@obordes littlebit late with my comment, but i found out too that every brand of mg996r has different torques wich are all far out of specs. Cheap brandless mg996r servo's even have different torques within the same brand, or sometimes give out at 2 or 3 kg. And 1 out of 10 brandless servo's you order don't even work at all. sg90 are even worse, sometimes entire batches do nothing, until you resolder the pots...
thank you
what is the maximum current? 6V

why is it so loud, it hums even when it is not working, I have the same sound and I don't like it, how to solve this problem
loud ? What you hear is the noise of gear. Numerical servos are even more noisy.

Wow is this real ?
As real as it can be with 4kg. Not really surprising, most servos are out of specs.
