Looking for a high-torque sensored brushless servo for a prosthetic hand.

Hi all – Thanks for the help in advance.

I am looking for a reversible high-torque continuous brushless sensored servo for a prosthetic hand that I am building. The servo will be turning a leadscrew which will in turn actuate the hand. Currently, I am testing using this servo: https://www.parallax.com/product/900-00360

While it is working, it barely has enough torque to turn the leadscrew, and I am very worried about it burning out. The hand that it is actuating provides resistance on the leadscrew nut via elastic joints. Here is a link to the hand (FlexyHand): https://www.thingiverse.com/thing:242639

I was looking at something like this: https://www.amazon.com/D3-LP-BF07S-brushless-profile-Applicable-Drifting/dp/B014CZBURA/ref=sr_1_5?m=A1SFMAWNL2DGN3&s=toys-and-games&ie=UTF8&qid=1522963819&sr=1-5&keywords=omg&refinements=p_6%3AA1SFMAWNL2DGN3 which provides almost 3 times the torque.

I need the servo to be sensored however because that is how I am able to tell if the hand is opened or closed.

Does anyone know of a servo that may fit my application? I have been searching for a while now and I am not finding anything. The order of relevance for this motor goes reversible/continuous>servo>sensored>high-torque(must be higher than Parallax one linked)>brushless. I am open to any suggestions.

Thanks again!
