i realy don't think there would be a problem do to the fact that the rutex drives says it uses hall inputs and the encoder has the inputs and the motor is your typical 3 phase AC(dc is interchangable for the most part) brushless motor. and the bridge can handle 34amps cont. drive is rated for 20 amps 100v.
the only thing I can see being a problem is the 100v limit (which is what the motor is rated for). There was another thread about the geckos not running at the max level do to problems with BEMF and voltage spikes and whatnot. I would assume that the rutex drives would have similar problems running at max voltage as well. But I don't know.
One would hope that the rating is a usuable number. personaly I believe if you state something should be run at 80% of rating then you overrated your product by 20%.
