Hi, I just burnt out my aliexpress linear actuator on my 30' ~4000kg yacht. It was a 12V 800N 20mm/s actuator. It was working nicely for a while (~15 mins) but the conditions were a bit rough and the boat was experiencing a bit of weather helm. I think it is a duty cycle problem. My actuator is rated to 25% duty cycle and in these conditions with the actuator being quite slow it was constantly making corrections
I'm looking to replace it and have found one that is 12V, 400N and 52mm/s with the thought that if the corrections are faster then less time the motor is moving between them and 400N still seems quite a reasonable amount of force? https://www.aliexpress.com/item/1005006225654918.html Interested on any opinions on whether or not that may solve my problem.
I also wondered whether people have experimented with the parameter "servo.period" as I guess that would effectively help manage duty cycle, but not sure at what cost to efficiency of steering corrections?
