control of brushless motor and use of ULN2003

[sabrahermassi]

I want to know how to control a brushless motor with a STM32F10 microcontroller ??
Can I use an ULN 2003 with this type of motor or not ??

for driving brushless motor u can not use ULN series ICs. it'll give only -ve (GND) supply to the motor it can't give +ve supply. because it has only open collector output. u need full bridge which can give bot +ve and -ve to motor terminal pins.

u can develop ur own 3ph H-bridge using MOSFET or IGBT. or u can go with readymade IC for BLDC driver for low power rating.
