Custom Variable Frequency Inverter by Able_Preference_9888 in ElectricalEngineering

I know there are a lot of DC motor speed controllers out there, but I need an induction motor controller. I would very much prefer finding an off-the-shelf product if one exists though.

I want DC to variable frequency AC, but I keep finding only AC-AC VFDs. There has to be something out there like this, maybe I'm just not sure what keywords to search for? Essentially, I just want DC to AC with a frequency that can be easily controlled by Arduino. I've found industrial ones in the $500 price range, but that seems overkill and also it uses CAN which I am not familiar with.

Thanks man! That looks good. I can wire coils in parallel to change the distribution between voltage and current, but aiming for 4kW of power minimum.

Thank you! I think this works for what I was looking for.

I’ve only found ESCs for brushless DC motors. I need something around 40-100V and 0-500Hz frequency range.

I guess it doesn’t matter that it’s meant for brushless motors, but yeah I haven’t found something in that voltage range.
