Balance
« on: August 30, 2007, 04:26:20 PM »
One of my 7.5 KVA ST alternators has had an attempt to balance it at the factory. The balance is rudimentary at best; a hole has been drilled in the fan and a nut and bolt packed out with slivers of core laminations has been attached. However, my other ST alternator has had no obvious balancing done.

1.   If you have an ST alternator – has yours been balanced; how has it been balanced?
2.   At what level of imbalance would it become appropriate to correct it ?
3.   Is there an easy DIY way of determining balance if you do not have something like a lathe or set of spindles to hold the shaft ?

Regards,
Ian

My ST 5 was not ballanced....
Its in need of some serious ballancing....

Trial and error with some clay for a staic ballance seems to be the easiest way for the DIYer ....

It's a Good Life, If You Don't Weaken
