Brushless motor controller

Hi, I am trying to locate a brushless motor driver with sensing capabilities. I have been having a hard time location something that would meet our needs. We are currently using a custom made controller but it lacks sensing.

It needs to be able to handle ~800W and 100V. The typical voltage is however about ~65V. It also must be light weight and contain some kind of sensing.

I have been able to find some industrial controllers that meet most of these specs, but as it is industrial they are over built and much to heavy.

I would appreciate any help in finding a controller that would meet our needs.

EDIT: I should mention that I am using DC voltage, not 3 phase or AC.

Thanks in advance!

i, don't know of any off the top of my head but you can try to google what you are looking for or you can try here
