Manually rotating the shaft of
my Anaheim Automation
motor with my fingers isn't making it.
So, I've scrounged up and assembled
some electronic components that I
intend to use to force the BLDC
motor shaft to rotate in lieu of my
If you take a look at the specifications for the BLY17 series of brushless
DC motors, you'll see that every motor
in the family has differing characteristics.
With that, it will be useless for me to
whip up a one-of-a-kind solution for
the motor that is currently sitting on
What if your BLDC motor
application requires a bit more torque
than my example project can offer?
What if you don't want to use a PIC
microcontroller as the motor controller?
I've rattled off only a couple of outside-of-the-box possibilities and I'm sure there
are many more we could expose. Rather
than approach the rest of this project
with a goal of manipulating only the
‘4000, we will assemble a microcontroller-based BLDC motor driver
using motor control building blocks
that can be scaled and applied to other
BLDC motor driver designs, as well as
the ‘4000. Now that you're privy to the
plan, let's get started.
Last time, I alluded to my preference of the PIC18F2431 microcontroller
as the master intelligence for this BLDC
