terminology for describing direction of rotation
terminology for describing direction of rotation
(OP)
I am buying a TEFC motor and I want to make sure I specify right direction of rotation (in case there is a directional fan...I'm not worried about swapping two leads if needed) in a concise and unambiguous manner.
The best I can come up with:
CCW when viewed from...
[*]motor ODE-to-DE
[*]or motor front-to-back,
[*]or motor-to-pump
[*]or standing at outboard end of motor
Does any of these sound reasonable or better suggestions?
I recall there is very precise terminology for describing horiziontal motor term box location (F1 and F2) but I don't recall NEMA MG1 giving me any clues on standard terminology to define direction of rotation on a horizontal motor.

Please note that the use of Sun as a reference was abandoned when companies started exporting machines to counttrie sout of the Equator.

But I'm left-handed, so YMMV.

dpc - CCW from O.D.E. should be unambiguous as well.
I guess I just made my original descriptions needlessly complicated by interjecting the "to" (ODE - to - DE). There are lots of good ways to say it if I get rid of the to.
By the way, interesting twist to call it "driven end" and "opposite driven end"... I think that is more descriptive than the usual "drive end" and "opposite drive end" which can confuse vibration people that are used to conventions like "driver to driven" for describing orientation from which rotation is viewed.

So, in the northern hemisphere, "Solar Direction" was the same as CW while it wasn't in the southern hemispere.
