When they say clockwise/ counterclockwise on rotation of the shaft on an electric motor, do they mean looking at the end of the shaft, or looking alongside the motor down the shaft? Putting a new electric motor on a hay elevator today, and I might as well get it right the first time.

facing the output shaft
CCW / LE or CCWLE Counter clockwise from the lead end
CCWSE Counter clockwise from the shaft end
CW Rotation Only Shaft can only rotate in a clockwise position
CW / OLE Clockwise opposite lead end
CWLE Clockwise from the lead end
CWSE Clockwise from the shaft end
Double Shaft / CCWLE Spins counter clockwise on a double shaft from the lead end
Double Shaft / CWSE Spins clockwise on a double shaft from the shaft end
CW / CCW or Reversible Clockwise or counterclockwise
ECW Either clockwise or counterclockwise, connected for clockwise rotation at factory
ECCW Either clockwise or counterclockwise, connected for counterclockwise rotation at factory
Reversing Plug Switching the reversing plug changes the rotation of the shaft
CW or CCW The real meaning of these labels is dependent on the manufacturer.

If the end is not given in the description it is reasonable to assume the rotation is given in SE shaft end.
CW; CWSE; and CCWLE would all be clock wise from the shaft end
CCW; CCWSE; and CWLE would all be counter clock wise from the shaft end.
CW; CWSE; and CCWLE would all be clock wise from the shaft end
CCW; CCWSE; and CWLE would all be counter clock wise from the shaft end.

There is and will be confusion on this. NEMA and IEC specify the same rotation differently. NEMA would say CW from Non-Drive end, IEC would say CCW from drive end. Best practice is to look for an arrow, or wiring info, or specify which end it is viewed from when designating the direction. Jim

Can you get one that's reversible? If wired wrong the first time, then just switch the wiring.
In the immortal words of some very smart guy whose name is lost in the sands of time, "Well, at least we know more now than we do than when we started." I had no idea this would be such a complex issue. So I guess I'll do what I originally planned- plug it in as it was wired from the factory, and if its wrong, switch a couple wires per the directions to get it to go the other way. We'll get those little suckers in the loft yet!

I thought John T would pick up on this one. Come to think of it I haven't seen him here for a while. Probably out motor homing. stan

I know hydraulic motors much better than electric but with hydraulic motors (and pumps) the rotation is always specified looking directly at the end of the shaft with it pointed towards you.
I am pretty sure Baldor motors are from the fan end of the motor. This might be the more common way but I am just guessing.
If you read the plates on the motor (assuming they are there) some specify one way and another will specify just the opposite.
Best is to wire it up and check.

Universal belief is that it is looking at the shaft end , however there are manufacturers that screw this up and cause confusion. Quality motors are marked with arrows.
