Hi,
I'm building a motor stage for university project. It took me a while to realize that what I needed is a what's called UV amplifier.
I Googled on this but were only able to find some very limited info:
ideas/concepts:
http://www.electromate.com/db_suppo...oidal vs. Sinusoidal Brushless Amplifiers.pdf
product:

Basically I have a motion control card with a pair of A/B phase output. It is already with commutation but I will need to lead them towards the amplifier to output 3 phase current to drive a BLDC motor.
I'd like to build it myself, but it looks like even if I want to buy there isn't much available on the market. It could be that I have not looked hard enough, but the one listed above is a PWM output stage. I'm looking for a linear stage.
So in summary, I'd like someone to get me started on this project. The requirement is 1) an amplifier that takes a pair of phase input with commutation; 2) output to drive a 3-phase BLDC motor; 3) the amplifier has to be analog, not PWM.
Thanks in advance,
Jay
