Where can I get terminal posts?

[Andrew TinsleyParticipant @andrewtinsley63637]

Hello,I am just converting some Crompton Parkinson 3 phase motors from star to delta.

They only have 3 terminals right now. But having unpicked the star points, I need another 3 connection terminals to convert to delta.

Can I find such beasties? No, probably because I am using the wrong search term! I know I could just use nuts and bolts and bodge the terminals, but I do like the cupped washers that you get with the genuine terminal posts.

I am going to use a larger piece of tufnol plate to get the 6 terminals in, so I may as well do a pukka job.

Thanks,

Andrew.

RS Components would be my first port of call

Not only do they have an excellent search facility, but many products have data-sheets available.

For the sake of political correctness, I should mention that many alternative suppliers are available

Hello Michael,

RS and Farnell were my first port of call. Nothing remotely like the required terminal posts as far as I could see. Thanks for the suggestion.

Digikey has similar.

(Don't know what they are like in the UK but in Canada the (US) company ships from the Canadian side of the border with prices in $CDN. They charge a very nominal $8 flat rate shipping such that, if I order before 8pm one day, I get it by noon the next. I could barely drive to a local store for $8).

Can't you buy a "Scrap" motor and scavenge them? Alternately any Motor rewinders in your area?

Having found a 6 terminal block for £25 inc P&P. I think I will make up some myself. I can't afford £100 to convert 4 motors from star to delta!!!!!!!!!!!!

Thanks all,

Andrew.

Not sure why you need 6 terminals – if it'll be a permanent change over, you only need 3.

When I did something similar I just added an extra ring terminal to each of the 3 posts.

Sorry, Andrew … I thought you were looking for individual ‘terminal posts’ to fill an existing block

I now assume, from your own findings, that it’s something more like these that you want:

… is that correct ?

Hello David and Michael,

I take the point that I don't need six terminals. But I would like to make it easy to go back to star if needed and the modern system for new motors is 6 terminals and 3 links. Much easier to do the deed that way and at least the terminal system is then to a modern "standard".

Michael your link is perfect, a standard six terminal block for less than a fiver. That will do me just fine. Thank you!

Living out in the sticks means a minimum of a 40 mile round trip to the nearest motor rewinder, so mail order wins hands down.

A sincere thanks to everyone for your time and suggestions.

Andrew.
