Brushless AD HOC servo

They will effectively lock due to the high reduction, they are something like 140:1

Winches also use wormgears quite often. The wormgear can turn a larger gear but not vice versa thereby locking in place.

All these cheap car winches use a special variation of a planetary gearbox to get their high reduction. One of the reasons they work so well with brushless motors is that they have loose fitting gears and lots of slop. That means the brushless motor can start turning with no load and the ESC gets sense feedback before the motor needs much torque to turn.
