On the board, it is written "FX-M 94V-0 E302652" but this gives no useful web-search results. However, on a dual-in-line package on the board, there is a sticker that says KB-97290-12. I googled that I got some hits related to my board; for example in this shop, I found a board that is identical to mine (labeled as "Original"), and the one they sell (labeled as "Replacement").

 

Hard to see that 'replacement' fitting n place of original, doesn't appear to have anything like the same connectors...

This is a very similar motor to yours, 180v/4A 1.5HP (1000W)

There are a few 'Treadmill controllers', that's motor controller and display/control unit, on eBay for around 120euro that will work with this motor or similar.

 

Hello,

My treadmill has been sitting around ever since the motor-controller board broke. Since I could not find a replacement for the board, I thought why not build a power supply myself. I do not need fancy speed control; one single speed value is enough for me, probably the value that makes the motor rotates at 75% of its maximum speed.

The label on the motor indicates that it needs a voltage of 180Vdc to operate and draws 4.6A of current. My idea is to have something that turns my house's 220Vac to 180Vdc; and research in the web yielded that a bridge rectifier can do the job. I still haven't dug too much into it because something caught my attention. Quite a few people indicated that a bridge rectifier is likely to blow up when the motor starts because of surge/starting current that far exceeds the normal operating current in intensity. I believe 4.6A is the value of the operating current that the motor draws when already started.

My motor has a label on it saying LifeGear together with values for voltage, current, horse power, and rounds per minutes; and that's it! Not a single word more. LifeGear is the manufacturer of the treadmill. Unfortunately, I could not find the datasheet of the motor anywhere to confirm anything about surge current values.

Finally, my question: Is it possible to have a bridge rectifier to operate my motor at a fixed speed without blowing up?

Cheers,
Amine.

I really really respect how hard everybody is trying to save your life. It is good to know that there are people who will stop us when we have a truly bad idea and even better that we have sense enough to ask first. This is a great forum with fantastic people. I'm also one of those people who knows enough to be dangerous but also enough to know when I should ask advice ahead of time.

 

Someone else might have already recommended this, but : why not diagnose what went wrong with the motor control from its original application?
