I want a welding turntable able to turn 500 pound chunks of metal with room to spare. The vertical load with the table horizontal is no problem, it's when I went horizontal with material offset the centerline. ie. saddles, fittings and such, that I smoked the brushes and commutator on the $1800 turntable I had.
I told a vendor what I needed and showed them the speed controller I had, they matched up the motor, BLDC driver and power supply. I assumed matching the speed controller I already had.
I figured when I bought this it would come with wiring schematics, blue wire goes here, green wire goes there type of thing.
I tried hooking it all up , but I'm in over my head. I found a diagram for the controller that shows where to connect the motor to it which is how I was able to run the wires you see in pictures.
The motor to the controller shows yellow, green and blue to U V W, but my motor has yellow green and red. I connected the red to where it shows blue, just because it seems right.
Now I am not sure how to connect the speed controller, I'm stuck. Please help me.
- How would I connect a toggle switch to change directions?
- How do I control speed?
- Would I be better off using a VFD?
PStechPaul has recently suggested I can probably apply voltage from a microcontroller DAC or filtered PWM, which really means nothing to me: still in the same boat, not knowing how to connect it.
A hyperlink was shared in the comments to a distributors' site that has good information on it.
Here is a link to a video of operation.Trying to figure out why my BDLC isn't running in 2 directions
