How do brushless motors make torque?? (Episode 5)

Описание к видео How do brushless motors make torque?? (Episode 5)

This week we discuss how motors sense position, how the hall effect works, and how brushless motors produce torque. Like, comment, and subscribe if ur into it.

Foot Notes:
Not all BLDC motors have hall sensors, in fact many that are not used for traction applications do not (drones come to mind). Controllers just generate a rotating magnetic field and let the rotor do its thing. Position can also be sensed from the BEMF so if steady state rotor position is not important hall sensing will be omitted. However, for position control, or torque control this is the standard/minimum.
