i need dynamometer graph for the hsr-1422cr motorand also does the motor has a self brake mechanism and what is the maximal moment the mechnism can handle.
(i need it for a lift)
These are some good questions you have there. 
We don’t have a dynamometer. The motor does brake when commanded to stop or the speed is decreased. I have no way to measure or quantify the maximum moment. Sorry…
Heellooo… honestly, asking for that kind of specification on a $13 hobby servo needs a reality check.
for a $130 servo maybe, for $1300 servo certainly, but do you really think there is a snowballs chance the people manufacturing a servo selling for $13 retail have even bothered generating this information, much less would consider publishing it if they had just so someone can come back at them and say they were off by 10%? 
Since they are inexpensive, it would probably best if you bought one and tested it under the conditions you expect to use it. This way you would have accurate data to work with.
