One question I still have is if steppers can both spin and step, why do both steppers and BLDC motors exist? I seems the stepper is more versatile.
Steppers are not nearly as efficient and have horrible power to weight ratio. They also cost more for a given power. You pay a lot in cost, size, weight and power for the very fine control they give you. The conventional BLDC is what makes electric vehicles possible, even electric aircraft.
