Any rotating motor is actually an AC machine. A DC motor or generator
has a commutator that switches the terminals at the appropriate point
through a rotation, thus either converting the alternating current to
DC, or vice-versa. If you had current of a single polarity, you would
be unable to produce a changing magnetic field. So no, a DC generator
is going to be subject to the same limitations as an AC motor (or
'generator'.)
