Where can I find Laminated sheets for coil core

[kancharla_g]

I need to buy a 'I' shaped CRGO laminated core sheets, is there any website where I can buy online?

Thanks

Welcome to the PF.

I would think they would be pretty easy to find. Have you just tried a Google search? Cores and laminations should hopefully be pretty easy to find. What are the dimensions you are looking for? Can you post the datasheet for the bobbin?

Hi Berkeman,
Thanks for the reply. Google search all selling wholesale min. 1 ton. Please suggest some websites. Do they also do customization according our requirement for hobby projects?

What is the application? What power levels, voltages, etc.? What physical size? You didn't post a link to the bobbin datasheet yet... Or will you be 3-D printing your own bobbins for these hobby projects? Do you have a hand-powered coil winder to wind the bobbins? What gauge wire will you be using?

No manufacturer will be interested in supplying the lamination material for only one transformer.

Is there a new transformer available that will do the job? Why do you not buy that product?

Most people who want an unusual transformer rewind a used transformer core to meet their specifications.
For many applications there are alternatives to laminated cores that are easier to fabricate without special tools.

How much power will your transformer handle, how big will the transformer be?

The thickness of the lamination material will be decided by frequency. You must therefor specify the application.
Will it be for a power supply, for audio or is it a pulse transformer?

A google search returns a lot of links for DIY transformers. Some of them even have calculators. I think you might find more specfic answers there than here on PF.

For a one-off custom transformer I use online laser cutting service, have the laminates cut in thin sheet metal to your own design, it's the fastest and cheapest.

Have you looked on famaga? They sell industrial equipment and might have it.

Can you provide a link into their website showing anything related to transformers and transformer construction? Thanks.

AutomationDirect is also an option, I know they have a lot to offer for electrical engineers. Famaga's a relatively new company that tries to compete with automationdirect.com and in order to acquire customers they have various of discount offers. I don't know much about transformers I just assumed they might have one. Just wanted to be helpful.

 

[berkeman]

Yeah, but transformer parts are pretty specialized. You almost need to go to magnetics-centric companies to find them. Thanks for trying to be helpful, though, and Welcome to the PF.
