Note that other treadmill motor controllers like the MC-60 are self contained All you need is to solder a speed pot onto a MC-60 board I found a non working Gold's Gym 450 treadmill on Craig's list for $10 and it had a MC-2100 motor control board This page describes how I built an external circuit to drive the MC-2100 control board- Hi Mr. Ivan the first circuit has been tested by me and it worked right at the first shot, so it surely works, but all these can be difficult for any newcomer i can understand that. Yes it should work properly for any load below 4000 watts 220V. Mr.Majumdar as you said at the begining "Here's a SIMPLE PWM based motor speed controller circuit which can be used for controlling a treadmill speed right from zero to maximum." Replace the motor controller with the manufacturer-approved replacement part. But before I soldered the components I did a test on a breadboard. But I have a question. Remove the MOSFET, connect an LED from pin3 to ground nine via a 1k resistor. 100 is 100 ohms, you can use lower values than this for the mosfet gate, sounds good : but on ic 2 pin 3 what dose 100 mean ?? Thank you very much for the quick answer. The auto door control design calls for a irf540 mosfet which is rated for 100v source and my motor is 110 with rectified source being around 150v will that be a problem for that mosfet?
