So you have dropped the false arguments against BLDC and admit there are troublesome rates of BDC failures occurring which the EV community should work together to solve?

Seems like that is the case.

Now you command me to design a system for you since your Google button remains broken? Yes sir.

There are many controllers which could be used. What are your desires?
Power?
Small form factor?
Reliability?
extra functions?
low cost?
CAN bus interface?
punch-card interface?

You could be enterprising like Heatpump and build your own. But that would require fixing your google button and using it. Not to mention a little math and some chutzpah. If you want to go the Ebay/salvage route there are plenty of powertec and other industrial controllers out there. If you want a new out-of-the-box EV-ready solution, why not use the Scott?

Again, if you want to learn about controllers, post a question in the controller section. You seem to be implying there aren't controller options for BLDC available which just shows everybody you haven't bothered to research the topic. If you can fix your google button, "BLDC controller" returns 762,000 hits. Might be a good place to start.

Your $10,000 motor is half the problem. There are tens of thousands of BLDC controllers, I want you to select a controller that would match your motor. The problem is there isn't an affordable EV controller that matches it.

Again, WHAT CONTROLLER?

Of what, world hunger? Do you realize how you sound?

Again, it's not "my" motor. I wouldn't use any air-cooled motor unless I got it real cheap on Ebay or something. I have repeatedly told you I only posted the stats because it shows that your argument of low torque is at worse a lie and at best uninformed drivel.

Go back and read my post. I already told you the answer to your question. What is the point of giving you information if you won't even bother to read it?

Jabbing at the reply button is not a great way to learn stuff.

Most people here are happy to share, but not when you act like a mindless bully.

Cheers

I was trying to figure out if he had a valid option for you. As it turns out, he doesn't. The cheapest controllers are currently $6000-7000 and I'm not sure they can hit the required voltage.

So BLDC/AC is off the table for anything above 50kw. (There are issues with the scott drive, not to mention it's untested).

You have the brushed DC recommendations.
