I have been off the forum for a while. Greetings to all my friends here.
I have two Hitec HS311 RC servos acting in a pan/tilt app. The control move a small circular pcb (110 mm diameter tightly loaded with smd) with a 3G camera, module etc on it.
I see the servos in effect "lock up" when the pcb (and consequently the servos) is powered up. When the power is removed the servos can free wheel. Obviously they are designed like this to holds control surfaces on RC aircraft rigid whilst in flight.
In my app the servos will be continuously powered up for months on end. I cannot detect any heat emanating from them on the test bench. What sort of life span could I expect to get from them in this role? Do the internal motors wear (over heat) even though they are not moving? I thought the windings insulation might break down etc.
Any advice will be appreciated.
