Re: Votol EM-200 Controller

Cyclone 18kw vs the new 4000w to QS?
Who has the most torque? It states the Cyclone can max out at 120nm at higher amperage.

Is the qs very underrated?

EMI/RFI Dangerous?

I have made a gokart. Rather powerfull i would say.
It weights around 160-165kg.
700amp and 180volt.

And I have recently been thinking about the EMI/RFI. How dangerous is it to sit so close to such much current rushing trough to the motor siting right behind me?

Best Regards

Thomas :)

Hi I have a question
How do you do if its "locked" or "unlocked"?
Its the factory which can unlock it to 200amp continous. But the warranty is lost then.
