bldc motor
hi !
Yes, you should be able to run your BLDC with a controller. Since you don't have position sensors, you'll need a sensorless one, or an open loop one, and you'll need to tune it.
If you are using a uC, you can directly implement code to control the motor (with a 3 phase FET bridge and FET drivers), but it'll take you a while if you're not familiar with motor control. Fun project though.
You could also hack a HDD motor controller...
Good luck !
