do you use hal sensors. how do you start the commutation? do you have to
first spin the field by electronic commutation, or just apply the power to
the coil based on hal sensor data?

I have been working on a drive for brushless servo motors. I just got the
prototype running, and I am impressed by how well it is working,
already. I'm working with a Pittman 4443 motor I got on eBay a while
ago. These would make great motors for small routers and desktop
mills. They are NEMA size 17 but long. Amazingly, the VHDL code for
the drive's CPLD worked first time! I sure didn't expect that! So, I am
already at the step to design a board for it.
