I have made a lot of videos on DIY treadmill motor power supplies and subsequently have had lots of questions and comments asking where to purchase specific parts. In this video I go over the parts needed for the 3 most common types of treadmill power supplies. If you are looking for information and schematics on how to hook all of this up you will need to look at my other videos. This is just the components needed. Links to these parts through Amazon are below.

Not being an electrical engineer I do not have any specs on the motor choke, what I can do however is offer you some guidelines. First of all bigger is better. I have several motor chokes ranging from the size of a tennis ball to the size of a soft ball and the bigger they are the better they work. Second the wire for the choke needs to be a minimum of 16 awg. If the wire is not that big or better it will not have the amperage capacity to allow the motor to work properly. Amperage is the most important spec. A lot of the chokes available on line are rated in mA. there are 1000 mA in an amp. Treadmill motors are rated in amps so most chokes available on line are several hundred times too small. Third they are not available on Amazon at least not inexpensively, there are a few privet sellers on Amazon selling used parts for big bucks but the available chokes on amazon are too small because they are not designed for a motor even though they look correct in the picture they are way too small. 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 wires, a transformer will have 3 or more. Also before I started doing videos chokes on eBay could be had for $25 or less shipped but now that more people are looking for them (due to my videos) the eBay sellers have raised their prices quite a bit. Your best bet might be the DIY option out of a Microwave transformer. Please let me know if I can be of further assistance.
