    i want to do my projects about designing a dc motor control.i plan to use PWM with half bridge mosfet using PIC..
    but the probs is,i dunno where to start, and i hav only few knowledge about that.
    can someone help me?tell me in details how its works..my DC motor specs is 24v dc,rated current is 10amps,rated speed 2700rpm and is a 180W..

    i wanna use 24v battery..

    Pic can only accepts 5v,so where i need to suppy my 24v battery??
    plzz help me..

    Use 5V for the PIC (an LM7805, LM309, or similar would work), and use that to control a transistor/MOSFET that actually drives the motor.

    so that 24v is goes to the mosfets?
    what type of PIC can is use..that is too many..i dunno which one is better..

    A PIC with just one PWM output is enough for your project. Also, it has to have an ADC as to read a pot and adjust the speed of the motor.
