    I assume that your motor already has commutation circuitry. In that case, you need to build a 'buck' converter and use a PIC with a hardware PWM port to drive the FET. If the motor has a tachometer output, you will need to drive the high side (using a P-channel FET), because most tachometers are ground-referenced.

    Wink How's your turbine ???

    Hi, JetPr

    Long time we didn't hear from you ...

    So, do not loose our good ol' habits ...

    I understand from your post you have a brushless ESC and you need a servo signal generator to drive it without using a R/C set ???

    is it true ??? ...

    sooo ...

    or simply GOOGLE " Servo driver " ... TONS of answers ( W/ 555, 4011, 324 ... Pics, Atmels, Freescale ... )

    IF there is the word "Problem" in your question ...
    certainly the answer is " RTFM " or " RTFDataSheet " !!!
