VESC | What kind of control is BLDC?



I am trying to figure out the difference in control between BLDC or FOC on the VESC. FOC is obviously field-oriented control, however is BLDC some sort of scalar control?


Trapezoidal commutation, in sensorless mode I think the rotor position is estimated by sensing the zero crossing of back EMF.
Here’s an interesting video of the technique:
