Update...So I have the drive motor, controller, throttle, battery etc all on the bench and it seems to be working well. I am waiting on the controllers for the two deck blade motors still. More on that later... i have a question on the fuse (don't have one yet). Not being familiar with these...

I'll check the resistance. Man, should I bust out the ol' oscilloscope? Now you're all thinking, "you have a 'scope and it's in the closet? WTH is wrong with you?" 😄🤣 I used to build valve guitar amps.

Thx for the link. Cheaper there. I'll order a couple. I just want to set the speed to around 2800 rpm, and then forget it.

Ok I think I found a controller that would work, what do you guys think of this one? I would get two, one for each of the 40V ryobi motors: https://www.ebay.com/itm/DC-6-50V-3-Phases-Brushless-Motor-Controller-No-Hall-BLDC-PWM-PLC-Driver-Board/253794933276?hash=item3b175b5a1c:g:~rsAAOSwLXFctH63...

I didn't see one without hall sensor. The wires are probably 14-gauge ? The wires in background are for my drive motor controller which are probably about 8-gauge? I think 22gauge wire can handle 10A so the thickness is likely more for resistance vs amp load? The ryobi controllers I saw have 8A...

Thanks for the input. Appreciated. The ebay photos for 40v ryobi motor controller shows the controller's labels with 8A or 10A printed on them. While they are only $15 I'll look around a bit more. I can spend a bit more than that for two controllers. Just want them to work well and not burn up...

So here's a link to ebay for a three phase controller 6-60v...

5Ah batter for 35m run time so since self propelled and that uses some juice probably about 5-7A draw tops?

I did look at part replacement pdf and tried to find the motor specs on the internet but I had no luck.

They supposedly came out of a ryobi 20inch electric self propelled walk behind single blade mower. Seems to be only one model. Yes it looks like three wires and the ad says brushless...

The motors have zero markings on them but I know the electric mower made by ryobi is 40v. Not sure still if they are brushless or brushed. I assume brushed since the OEM would likely cheap out every other could. Heres a pic, they just arrived. Yes I know there's some unknowns which is why I am...

So I'm not sure what specifically to look for in a controller, I see they are somewhat inexpensive: https://www.amazon.com/gp/product/B086JYJDYN/?tag=pfamazon01-20 If I were to buy two controllers for the two 40vdc motos used for the two mower blades, what should I look for?

The controller for them says 2500/2800 RPM on it. The markings are minimal, chinese stuff...unfortunately.

I don't have the motors yet, I got two used motors from ebay that used to be in Ryobi 20inch electric mowers to run the blade. I don't know if they are brushed or brushless. I assume RPM, there is a controller on ebay?

Ok so then I could get a second controller to control the two identical 40vdc motors. I suppose that should be fine since they are the same, yes?
