Currently we have a HS-422 servo motor and we are trying to lift 1000 grams (2.2lbs) with it. when we powered it at max voltage and current it was still unable to lift the weight. I am wondering what servo would be capable of lifting this much, with ease. we also have Pololu micro servo controller, it would be nice if the new servo could use this controller also.
Some other things to add, this is being used on a robot for one of my Mech. Engineering courses. we are required to use a NI MyRIO controller to control the robot. we have not been able to use the myrio because we cannot get past lifting the weight in bench testing.
Any and all help will be appreciated!
Thanks!!
Try going up to a HS-645MG
The rotational force (a.k.a “torque”) a servo can provide is given in ounce-inches or Kilogram-centimeters.
The 422 can provide a maximum of 4.1Kg-cm at 6V (3.3Kg-cm at 4.8V)
Using the maximum value however means that it can lift ~1Kg at a distance of 4cm away from the axis of rotation when 6V is applied.
Your power supply also needs to be able to provide between 4.8V to 6V and at least 450mA of current.
The 645MG can provide up to 9.6Kg-cm (more than double the torque of the 422).

Thank you for your timely responses! I will be double checking all of my measurements and loads that could be applied and check back with everyone.
Thanks again for the help and advice!
