    Help. This is my first time to build a sensored bldc motor controller. What considerations should i take when building a bldc motor controller? I used AN957 as a reference for my sensored bldc controller. Please give some feedback and suggestions regarding my circuit below. My dspic33f outputs PWM and passes through the driver circuit then goes to the motor. The hall sensor output now goes to the dspic. I used 2 switches for starting the motor and the other switch for direction and a potentiometer to vary the duty cycle.

    The Ir2110 won't work well for this. You need a driver with a charge pump so you can run the motor at all speeds.

    It will work perfectly fine! I have used this type of gate drive in motor drives and it has worked perfectly fine.
