Hi Mike99,
I am pretty sure that motor is a brushed DC PM motor, so it has 2 terminals for the armature. All you have to do is reverse the polarity on the 2 terminals and it will rotate reverse direction.
The motor may have a preferred direction of rotation dealing with a fan or brush angle. But it will reverse simply by switching the positive and negative at the terminals. You may want to check with the manufacturer to be sure there are no other issues.
