    Hello, This is my first post, I did not see a get acquainted or introduce forum.
    being new, I most likely over looked it.
    If I have made a grievious error PLEASE forgive this unworthy newbie !!!!


    My name is Frodo, I am a plumber, and a tinkerer..I am working on a small project that I need some help on.
    First, I can wire a house, and I have built a 22o controller for a big cray fish pot
    but do not know anything about circuit boards.

    I am attempting to turn a golds gym treadmill in to a tumbler'

    attached are pictures of the board, the motor
    in first picture, I have numbered what i think is power to the board. If i cut #1 cap the board, install a pin/wire

    is this the power for the motor less all the other junk.

    all i want is power..I will buy a potentometer to change speed..

    OR.If any way I can use what I have?
    I also have the control panel.
    WITH a mp-3 player and speakers..I dont need it or want it
    also a NICE fan and motor for the incline power strip 001.JPG treadmill 002.JPG treadmill 001.JPG treadmill 006.JPG treadmill 005.JPG treadmill 004.JPG tread mill 004.JPG tread mill 003.JPG tread mill 002.JPG tread mill 001.JPG
    more on theses freebies later
    Can you guys help me out????

    Is there any numbers on the board, it looks familiar, you should be able to hook power directly up to the board, there were basically two types of control, one is a simple pot, the other a PWM signal from a separate circuit.
    Generally these T.M. boards require zero start position on the pot before the motor will turn.

    The controller is for a DC motor.
    Here is the manual.
    I also have the schematic if needed.

    .
    where is the manual?

    and yes, the schematic if possible Please?


    do you have a use for the fan, mp3 player or the incline motor/actuator

    and all the rest of electronics this has? a led screen ETC

    Not relevant but I cannot help it. :D

    Is your name really "Frodo" o_O. I thought that was made up name for TLOTR.

    Back to topic. If the POT is the control device then you can use the controller to drive the motor.

    Where is the manual Max ?

    yes i was going to control it with a pot

    I googled and found this is the ac/dc converter

    so i guess all i need to do is use that

    If I cut at the red circle, install a wire. is that all i need for power?


    RIFF.....no my name is not Frodo it is a secret, I'll pm

    Here it is.
    Also you want to remove the flywheel if it has one.

    Hate to admit it, but you guys are going to have to dumb it down.

    i am a plumber, not an electrical whiz like you.

    I can do electrical work, but it is wireing a building not a board.

    here is a control I made. My only dabble into electronics

    Ok do you want to remove the treadmill running motor and control the speed separately, you can use the motor speed pcb that came with it, or make your own using a simple light dimmer and a bridge rectifier?

    while i was on the phone, I spotted an old ac/dc convertr i had for a cooler

    i cut the the cigerete lighter end off of it, and the motor is humming like a happy little bird

    to control it. you [​IMG] said a recitifer? is that a recitifer? the 1R 829P ? in the middle of the screen?

    if it is, do i unsolder it. then solder it to the blk wire on the dimmer
    if so..their are 3 stubs ! 2 3 which 2 do i use. 1 and 3 cut 2 off?

    also...would it be between the dimmer and motor? 3d78ddcc89ef683226ccea312e96ed94.jpg

    Your T.M. drive is the better bet for a drive, it is PWM output over a Triac and bridge bridge control which starts to get noisy when you lower the rpm.
    The IR semi's are Mosfets.

    If your going to use the treadmill pcb for speed control, you need to look at the circuit on post#11, which i dont think you have the technical ability to do, no offence!, as it involves pulsed timing from the micro to feed the thyristor bridge rectifier for speed control, if you feel confident to go ahead with this then lets go that way,

    otherwise
    use the light dimmer application i posted.#14

    Where's Samwise Gamjee ? :D
    if you do not have one, you need to find him in AAC. He is always there for Frodo.

    He tried to steal the gold ring and was dispatched with extreme prejudice.

    I think,,doggydave is correct in assessing my abilities. NO offence tak'n.

    truth is the truth, so the dimmer switch is the prudent path to take.

    I finished building it, it runs with out any control.

    I Do not like it with out control finished tumbler 002.JPG

    You have the PWM board I am not sure why you would not try it?
    BTW what is a 220 controller for a cray fish pot? Need that to raise it?
