hi, i'm new to the forum but i'm looking to build a healthy motor controller with more than enough power to do whatever needs to be done. I'm running a warp7 dc series motor on an electric snowmobile conversion, and need a new motor controller. ideally i'd like to run as much as 400 volts to the motor controller, and then limit that to a max of 170 volts out to the motor. i haven't yet read all of the pages here but i'm sure someone has talked about this already, if one of you could kindly point me in the right direction. i guess what i'm asking is what all would i have to change in order to operate the controller with a 400V max instead of 144. to me it seems like this would mostly be a change in the power board of the controller, by switching to components that can handle a higher voltage.
