Servo Size
« on: March 26, 2017, 08:53:18 AM »
Can someone please explain what rules manufacturers use to dimension servo's with regard to height.

For instance the Tower Pro Mg16R are list as 29x11.2x29 on many sites however if you thought the servo would fit say between two ribs say 30mm apart then you would be wrong.  The height is actually 37.2m.

So the first dimension can be assumed to be the width (less fixings) the second is the thickness and the third who only knows.

This Tower Pro site seems to have dimensions on the drawing that agree with your measurements, so no idea why they are published differently elsewhere (even in their own summary data):-

A lot of the time they only seem to take the height measurement to the top of the servo case before the output shaft, so they can often be quite a bit taller than you think.

For those who use HK, dimension A is the dimension between the servo base and the top of the splines. Beware this is not the dimenion with the arm installed so you ned to add on at least another couple of mm's.
