Hi Guys
Needing some help here, I am possibly going to need to source a three phase starter in the very near future. Only problem is the machine that the starter is attached to is ancient.
To give you the scope of the issue, my dad has a old table saw in his work shop and it has a three phase motor to power it. When we try to start it the hold on contact doesn't hold so it stays on.
Now I have two main theories and one of them is the contactors/starter is knackered and needs replaced, the other is there is a issue with one of the phases, now I have had a quick look and see to see if I can spot any potential causes initially I thought it was needing a clean out due to sawdust build up, so I done that as well as made sure all connections were tightened and the contactor was moving freely and all was fine. No signs of any damage to any parts everythign looks good.
That is where I decided to stop and put everything back together, I am not messing around with 3 phase when I don't know much about it, I can do most of the theory and that but in practise I prefer to have a qualified electrician with me when I need to do these sort of things.
I don't have any model numbers as of yet as I couldn't get any. I will try and get some in the next few days, don't think it matters much really as with Christmas being next week I doubt we will need to use it and also doubt we will get our spark up of his backside to have a look as he is now off for Christmas he has strictly stated that if anyone bothers him this Christmas he won't be happy.
Also what other issues could cause the contactor not to hold on? I kind of thought the cold could play a part but in the past years we have been colder and it has worked, really for this time of year the workshop is warm.
