Comment on Why do we still use stepper motors?

BLDC and AC servos maintain full torque at stop too, and have about 2-3× the torque of a stepper of similar size.

Huh, this is true about BLDCs as well? I remember seeing in a video that BLDCs tend to have very poor torque output when stopped and especially when at low speeds, whereas AC motors have a pretty much flat torque curve until they get fairly fast. I’d be interested to know if this is true.
