CW / CCW Electric Motors

Typically, in my experience, it's stated CW or CCW facing the shaft.

I'm not saying you're right or wrong, but I have seen it stated both ways.

I have seen it stated both ways also, but the vast majority of times it is stated, "facing shaft."

The standard is as viewed from drive end in India

Indian Standard IS 325 Annexure B (Information to be given at the stage of enquiry and placement of order)

Clause 13 states : "Direction of rotation Viewing from Drive End"

It should be as viewed from the shaft. That's the standard way in the US. Europeans used to do it reverse, but I think they've all standardized now.

Usually, we will base on the motor driving shaft for the direction to specified as CW or CCW rotation as the driving shaft is that one that drive the load.

Normally the specification dictates this. IEC specification specifies from the shaft of the motor. Not too familiar with Nema specifications, so I'm not sure what they specify.

I don't normally revert to theology since Chris and Moose take a dim view, but I went to scripture for this. McMaster-Carr consistently says, "...CW as viewed from shaft end...", or "...CW as viewed from lead end..." Almost always, it's from shaft.

Now, the hard part is figuring out how to spec it when it has a shaft on both ends.

Thank you all for your input. Shaft end it is.

DC motors go's buy the outher end

It doesn't matter with a DC motor because their rotation is determined by how you connect it to the power source.

Not necessarilty true. You can reverse the direction of a DC motor without accessing the feed connections by reversing the armature leads.

As to direction, I have always seen it to be referended from the load end.

it differs from make to make
