I suggested converting the servo to continuous rotation, not to modify it's gear ratio.
Yes, but since he already tested it, he might have modded it already and since he needs the power at a radius of 8cm, the gear ratio will have to be changed, or it won't have the power to lift the weight.
Although I somehow had got it at 14kg (probably crept in from another post), it is only 10kg, so my calculations was a bit off (it will be about 30% faster).
This modification will allow the servo to produce the same torque and at the same speed that it was originally designed and built to.
Obviously, but since he need 10kg force at 80mm or 80 kgf-cm, it will
need to be geared down - or did you imagine that it would work without a gear reduction?
The modification will allow it to move it's output shaft greater than the common 180 degrees.
Yeah well, modding servos, or the purpose of doing it, aren't exactly secrets.
Not all servos are build for 180° though. Some only goes 90°, some goes 2..3 revs and then there's the continuously rotating types that's made without the end stops from the factory.
Slow is relative.
Consider the life span of a Pansy compared to an Oak Tree.
Who's faster then, a pansy or an oak tree?
Of course slow is relative and (well, I better not go there...
Comparing a geared down servo to any old gearhead motor of almost whatever size able to lift the weight, the servo will be relatively
Comparing it to a killer snail, it would be fast, of course, but since the snail would be quite impractical, I assume the OP can deduct this, if not... Lucky I gave him the numbers, making him able to judge for himself, right?
The OP has not replied with a time constraint yet.
He hasn't provided details with the required height to lift the load either, which will affect time to lift.
Precisely... Like I didn't said that he shouldn't use a servo, I just told him the likely speed he'd get.
Apparently you chose to consider it a personal insult - well, that's really your problem and I don't see how that is helping the OP.
