HI,
Is there a board more powerful than a mesa 8i20 for brushless ac motors ?
I need at least 600V / 12A
What mesa answered me :
"only driver 8i20 is for big AC motors from Mesa product
but i no recommend the driver for these"

Thx

The 8i20 is 400V 30A. Your motors will probably run very well at 300V, but at about half the maximum speed (which is rarely a problem for axis motors).

Might work for you.
