Have just located a comparative diagram of the two types side by side.
Notably, the curly inductor symbols in the 1000 are the field windings, and the "MOTOR" is the rotor. because of this, if you reverse the polarity of the feed, the magnetic fields of both static field and moving rotor reverse, so the reversals cancel each other out and the machine turns in the same direction, so the machine will turn if fed with AC.
