Electric Motor, Circuit Breaker Help PLEASE!

[Snattlerake]

Wifey has one at home with a problem that whenever it wants to it just dies. I have looked it over real well and see no obvious problems. But every time I install the cover back on the circuit board, it acts up again. This tells me it is heat related.

This is definitely powered by an inverter in the machine. 50/60hz nameplate specification doesn't really matter when the input power is being rectified.

I realize that. He asked if it might be from Europe and I was merely pointing out that couldn’t be with it being 60HZ.

What is your "electrician" calling a breaker? Something in the treadmill or in your house electrical box?

I see no breaker. All I see is a three phase motor and a line to Load connection makup box.

Do you have the complete model number and electrical schematic?

He probably means the built in thermal overloads. They're not "resettable" they have to cool down to reset themselves.

Catch 22, if you use a higher value thermistor, you run the risk of damaging the other components. If you run a lower one you won't get the full performance.

You’ll need to place a 220/240 vac Single Phase Input to 240 vac 3 Phase Output Transformer between as 220/240 vac Outlet. 3 Phase Electrical Service in generally used for commercial/industrial applications.

What exactly is it doing or not doing? Does it power on but not drive?

Treadmills typically uses a 3phase motor. I've fixed several over the years. Most were the motor controller.

Edit: Here is the service manual (Or likely close if it isn't a v2) for that treadmill.

Just cut your losses and start using it as it was intended…..clothes hanger. That’s what they all end up as in the end I thought

You win. Mods please lock......

Didn’t realize this was a competition. Just a bunch of people trying to help you out which apparently was a waste of your time as well as mine.

Thanks for all the replies and to the guy who said jsut return it or use it for it's intended purpose as a clothes hanger/storage rack. Probably truth right there.

So, last night I send a big, long email sort of putting them on blast about all this. I think I was partially correct and partially wrong about the info I claimed in my email to them. But anyways, we've had literally about 25 emails going back and forth on an email chain for about the last 3-4 months trying to sold the issues. Finally a guy who's been the main POC on the emails called me to explain things. He said this treadmill IS setup to use standard household 115V power but does need it's own dedicated power outlet. Apparently in the literature it states a dedicated "Nema 5-20P 20A" receptical is required. That may be where I didn't pay attention or whatever. But if what you guys say is true, which I totally believe, that treadmills typically use a VFD "device" and that is what adjusts the power/speed, they never mentioned anything about this feature and would have caused a lot less heartburn on my end. The guy on the phone didn't mention this at all but was 100% positive it would work off 115v plug, probably because of the VFD. He shipped out to me today to an adapter to be able to plug my cord into a 115v outlet that will acept the cord currently on the machine as well as ship out a standard 115v cord that is apparently easily installed on the machine to use inplace of what it came with.

I told him my electrician took the dedicated 220V outlet and converted it to a 110V outlet and the machine ran very slow with what seemed like almost no power. Guy on phone said that if the "chip or board" on the treadmill was damaged from me originally plugging the cord it came with to a 220v outlet he would send out a service tech and replace the board or chip that may have fried.

I may not have stated everything correctly but hope it will be worked out with the new adapter and cord they are shipping to me. Time will tell. And thanks to everyone who chimed in and the breadth of knowledge on her is pretty fantastic.

??? I was the OP not SPDguns.
