I have been told the way to determine wether a motor is spinning clockwise or counter clockwise is to look at it from the back of the motor ( the opposite side of the output shaft). Is this correct? I apologize i'm not in the correct section of this forum. I also noticed iI cannot delete it to put it in the "general discussion" section.

Rizer, my experience is just the opposite. Look at the end of the shaft for direction(VFSE). If the motor is double shafted, look at the end with the leads(VFLE). Some manufacturers might use the opposite of this, but this is the only way I've seen them.

The motors I've ordered have been tagged cw or ccw on the shaft end. Its my experience that you look at the shaft from the shaft end to determine rotation. My experience is strickly fractional hp if that makes a difference?

I believe NEMA Standard MG1 used to define rotation of small- and medium-sized motors and generators as “viewed [ODE] opposite the drive end” but MG1-2002(condensed) seems quiet on the matter. IIRC, NEMA standards never defined a particular rotation for a given phase sequence.
