Hello, I built this circuit on Proteus to drive a brushless dc motor by using 555 timers in monostable mode I know this is not a efficient way but i am just trying. this actually works by using variable resistors in place of R1 R2 and R3 chancing resistance changes pulse duration but driving with 3 resistor is not a practical way so i wonder if i could make it voltage controlled in single point or is this circuit just a trash which gives noting ? is it works if i just change the power voltage in a specified interval ? Please give me your comments on circuit and please help me. Thank you.
