[TowerTalk] rotating tower or stack : rpm

[Richard Riley]

Hi guys,

my previous post (reference soft-start and frequency regulation of motor on a rotating tower) drew no responses :( :(...
...so I'll try it from another angle.  I'm about to erect 102ft of 20inch- to- a-side, triangular rotating tower (loaded with 12-15m boomed monobanders from 40-10) on a 3 phase motor, with a projected speed of 1rpm..and am concerned about the potential for start/stop stress.

You have a large stack or a rotating tower.

How fast does it rotate?

Have you employed a soft-start-stop system to prevent mechanical shock?

If so, what did you choose?

Your input appreciated!
