A brushless motor requires a motor controller, and for most of us, this means cheap Electronic Speed Controllers (ESC) from a warehouse in China. [Ben] had a better idea: build his own ESC.
By implementing proper control algorithms (such as field-oriented control) on an ARM7 processor-based MCU, three-phase brushless motors ... Would the motor be a Permanent magnet Synchronous motor, the ...
a big help for troubleshooting your circuit. Once you’ve seen the videos after the break you’ll probably come to the conclusion that this is an impractical way to use a brushless motor.
