John Minchell Posted March 3, 2023 Author Share Posted March 3, 2023 Thanks for all the comments chaps. Looked at continuous rotation servos and also just modifying a standard one. They rotate too slowly and winding in 30m of line would take a few minutes. We want to avoid all specially written software or extra electronics - so a low Kv outrunner controlled with a standard ESC and some time and amp spike sensors and limit switches should do the job. Still looking for a commercially available small cheap low Kv motor though. Don't want the extra complexity of gearboxes. Quote Link to comment Share on other sites More sharing options...
Andy Stephenson Posted March 3, 2023 Share Posted March 3, 2023 I would think that the type of brushless motor used for camera stabilisation would be low KV as they are wound for torque not speed. 1 Quote Link to comment Share on other sites More sharing options...
