The tags esc (113 questions) and speedcontroller (89 questions) are essentially the same thing, and both poorly named (cryptic or unhyphenated). I propose that they should be merged/synonymized, perhaps to something like speed-controller or motor-controller, but in any case there should not be two tags.
I'm bringing this up on meta because they both have a substantial number of questions, and neither one is a good name for a mere synonym proposal, so it seems worth moderator action. (I have been trying to remove controller, an ambiguous tag whose own excerpt says it shouldn't be used, and a significant fraction of its uses are about motor controllers.)
Caveats:
The speedcontroller excerpt claims that it could be used e.g. for devices which control fuel flow to an engine. This seems unlikely to be useful or used.
It might make sense to make further distinctions:
- brushless motor controllers vs. brushed motor controllers (we already have brushed-dc-motor and brushless-dc-motor, which could be taken as supporting the distinction or as that we should use those tags instead)
- digital/PWM control vs. various more specialized/simplified things
and arguably esc might mean one of those, but I don't think it is consistently used that way, and I think there should be a tag that suits all-kinds-of-motor-controllers since they have common elements.
