Treadmill Motor Control

I have a Horizon T101-04 treadmill that has a control problem. The motor is definitely good. I suspect that the motor control board is good, and the control panel board is bad. The control will not reset or go into diagnostic mode. I want to replace either the control panel board or the entire control system. The motor is 90V DC. For amperage, the motor label says "19A S6 25%" which has no meaning that I understand, other than perhaps that the maximum amperage is 19. The label says "APMS" rather than "AMPS", and I wonder if the "S6" is supposed to be "SC" for "stall current." All of the characters on the label are very legible. To replace the entire set of controls, I can use an industrial DC motor control, but how much horsepower does the control actually need to be able to provide? I don't think that the one on the treadmill actually provides 19A, and is probably close to 1 HP or so in its capability.  To replace the control panel with something else and keep the existing motor control, what do I need? Do I need some type of complex driver circuit? Does it need feed back from tach sensor to do a good job of keeping the speed steady?  If it will work well, I want a simple control set up like a KB Electronics KBMD-240D to which I will add a safety cut-off switch with a lanyard.

Treadmill Motor Controller

HI, I would like to make a very simple controller my treadmill's Motor. Its MoBo went bad and I dont wanna fork over $200 for a new one. The motor works fine. I just want to make a very basic DC Motor speed controller. I know just a simple Pot or other variable resistor wont do.Will it? I've been messing around with Electronics since I was 9 so I'm not afraid to solder up some circuits even if its a complicated one. Im looking to spend around $50. Thanks.

How to use a potentiometer with this treadmill motor and speed controller?

Hi everyone I found this forum after doing a lot of searching on controlling the speed on a treadmill motor without using the big bulky digital display unit that sits on top of the treadmill. I bought a really nice Nordic Track for 10 dollars on Craigslist and I thought I would be able to figure out how to do this but apparently I was wrong. I have seen a lot of material regarding the MC-60 speed controller unit but nothing about the speed controller that came on the treadmill that I bought which was the MC-2100 Rev B. I will attach a couple of pictures of the board and specifically the wires coming from the display unit that go into the board. I have a 5k pot but I really dont know what to do with it and I am afraid to just start experimenting because I dont want to burn up the motor or the board. I would be happy to post any other pictures or add any other information that might be of help if anyone asks for it. Of course I would like to turn this little project into a lathe if I can ever get everything sorted out. btw the motor is a 2.25 hp cont duty. If the potentiometer wont work, I would love to hear about other ideas to be able to control the speed using this board and motor. Thanks everyone

Bike Powered Dog Treadmill

There are some days which my husky and I are unable to run outside. For those days, I use my exercise bike. But my husky is out of her mind with boredom if she cannot run. While I use my bike, I am wishing that it could power a treadmill for her to run on. I am aware that dog-powered (manual) and electric dog treadmills are available for purchase. I have visited sites that give instructions on how to make a dog-powered treadmill. And I know that a regular treadmill for humans can be used for dogs (with training). But I have a few reasons for leaning towards the idea of a bike-powered dog treadmill: 1) We workout together. Dog-powered treadmills usually require that the dog be constantly motivated to run, whether it be vocal cheering or physical nudges (or both). I do not think I will be able to exercise alongside her if I must stop to do this. 2) I do not want to use more electricity than I have to. We are all trying to save energy for whatever reason. So electric treadmills are a bit much. I am mechanically inclined, but I cannot produce plans of this scale. I am hoping that I do not need to do anything more than soldering or welding. Incorporating manufactured parts would be ideal. Any and all (practical, safe, and realistic) help would be greatly appreciated! Thank you, everyone! P.S. The use of any bike will do for this project. It does not have to be an exercise bike, though that would be nice as well.

P.M. D.C. Motor for Treadmill

Hi I am working on an Image 15.0 R Treadmill. As soon as you start it , it shuts down as if the circuit has been interrupted. I unhooked the drive belt so that there was no resistance to it and it does the same still. The speed sensor seems to be working okay so I pulled the controller (board) and tried re-flowing it. as I flip the treadmills switch on not starting the treadmill-just turning the power on the motor runs for about 3 seconds. Because the cover is off while I am working on it I can see that during that 3 second window the motor has a spark (bolt) from one of the bolts to the post (I think stater) the one that if the motor were disassembled the part spinning inside the copper wind. I don't remember what it's called (armature?) Anyway this arching does not re-occur unless I completely unhook the board once more and re-assemble. After re-flow the motor still just begins to load (start) bumps about 1/2 a rotation and stops. I read an article here that Iceng had commented about bringing his P.M. D.C. Motor model # c335483304 back to life......it is the exact motor....my girlfriend has been on me about fixing her treadmill so here I am. Anything would be of great interest and help to me. Thanks a million in advance. Troy

Simple (I hope) Treadmill Incline indicator

Hi,  I have an older treadmill that has a button to control the incline, but doesn't display the incline. I have a treadmill program app on my iPhone that guides me through a exercise session by telling me to set the speed and incline many times throughout the 30 minutes I am on the treadmill.  I would like to build something to display the incline as I adjust it.  I have just enough memory from all my childhood Radio Shack projects learning to not be afraid to attempt this and also the vast knowledge of the internet :) I have already calculated and marked the incline differences on the frame of the treadmill near my feet but I can't really see it well. I figure a small LED display would work best. I can visualize running wires up and down the frame to the LED display to an arm that will move with the treadmill while hitting contacts. I am sure I can get this to work but it sure seems like a lot of wires so I feel I am missing something. If anyone has any suggestions about an easy way to do this or can draw me a diagram of what I would need, I would be forever grateful. Thanks, Cindy in Indy

How does the emergency shut off work on a LifeFitness treadmill? Answered

First let me say that  I DON'T want to defeat the system.  If I or anyone else  trips, stumbles, passes out, or whatever,  I WANT  the thing to shut down.  I don't want anyone using the machine without  being clipped in to the shut-off.  LifeFitness has a good system in which nothing moves unless the emergency shut off is in place. I'm asking for the obvious reason, the string and clip with the little magnet(?) thing  is lost.  If this is a fast and easy thing to put together, I'd rather do that than order one from the company.   If you know but aren't comfortable putting the information out in public,  please PM me.
