How is this different from other high voltage PWM current designs?

Yes they are designed by my friend Graham; I have seen
them work with a rare earth 2.amps nema 23 motors
I have 4 and combined with the constant current drivers
that he also designed I measured 280 rpm and this motors
have a 7/8 diameter pulley and I could not stop the motors at that speed and
burned my fingers, the imput
voltage is max 32v and when I was trying them the voltage was 30v , I was
waiting to see if the constant current drivers would work with the former
driver cards
before contacting the list about them

mariano
