That's the normal/traditional advantage of "brushed" motors vs synchronous motors, but the brushed motors have the massive disadvantage of having a mechanical contact (the brushes) that wear off, need to be sealed, etc. The advantage here is that it behaves like a brushed motor, but without the brushes!
