I wanted to convert my wood cutting bandsaw into a metal cutting bandsaw and to do so needed to be able to slow it way down. A treadmill motor give me a huge range of adjustability. Everything was DIY including the power supply and the drive pulley.

The choke in most of my videos is part number 130993. Instead of getting one new I would get a used one. A lot of treadmills come with a choke. Go to eBay and search “treadmill motor choke” BUT know that most people on eBay don’t know what they have and the word "transformer" will also appear in most listings. Problem is a choke and a transformer look almost identical so some listings are for transformers and some are fore chokes because the sellers think they are interchangeable. They are not. They would only be interchangeable if you modify a transformer to work as a choke. (see my DIY choke video) To tell the difference count the wires. A choke will only have 2, a transformer will have 3 or more. Please let me know if I can be of further assistance.
