Hi,
I know this isn't a mechanical eng. forum, but I wanted to ask because many of you surely have a lot experience in using servos/motors in your projects.
I have a solar panel screwed onto a shaft which connects directly to a servo motor shaft. How much should the torque rating of the servo be to be able to rotate it ? I mean an estimate of the minimum torque required. The panel weighs 0.8kg plus a few grams for the solar panel holder (made of perspex). No gears are used.
I would need the servo shaft to rotate a total of about 135 degrees, rotating a few degrees every hour for eight hours (It will operate like a stepper, stepping during each hour). The speed of rotation is not important, as long as it rotates. The panel's length is 32cm and height is 18 cm. It is a solar tracker.
There will also be another servo to rotate the round base.
A rough diagram is attached below.
Thanks.
