Hello all I have a motor that is wired for 110 and I would like to make it a 220 but I am no electrition and do not understand the abbreviation they use on the side of the motor
I suspect CW ROT means counter rotation. There are people here more familiar with electrical terms than me. I am sure this will draw some better answers.

Show a picture of the back of the motor where the wires are connected.
According to your plate data, there should be 5 posts (connections.) For 230 volts, connect the blue wire to the #5 post (disconnect from the #3 post.) and the white wire to post #3 (from the #1 post). This will give you 230volt 12 amp clockwise rotation. For counter clockwise rotation (CCW) switch the #2 post with the #4 post wires (red and black.)
Thank you for your reply what you say seems to make sense but I'm still at a loss with wiring it for 220 I hope someone can help me I really need this for a project I'm working on

You will need a 220v outlet. Is that available and can you post a picture? With a picture we can tell you what NEMA code plug is at the wall, which will tell us a little about your available power. You will need a 220v male plug to match the female receptacle in the wall.
Which wall socket do you have according the above chart?
I googled the question
Here is an answer;
CCW or CW Rotation? - Electric motors & generators ...www.eng-tips.com › viewthread
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.

Next to the point where the cord goes into the motor should be a small plate, the terminals 1-5 should be in there, Attach the wires as directed by the label.
L1 and L2 will be where you connect you wires from the panel for 115 L2 would be the neutral (white) wire, for 208-240 the other color besides black or green if white is used a red marker should be used to delineate it, at both ends of the cord......if you wish to do thing correctly.
Black is always L1 and Green is always the chassis ground ...unless your working out of the U.S. or on imported equipment, then Google the wiring color conventions for your locale.
Terminals 1-5 change the internal connections of the motor.
For all practical purposes 220-230 are effectively the same voltage, if its 208 then you will draw a fractional difference in amperage and the motor speed will be marginally off.
208 voltage is the product of having a transformer wired to a wye spec which causes voltage to be a multiplier of 1.73 times any single line to ground voltage. (usually found in three phase). or exceedingly rarely it is the hi leg of a open delta wiring of the transformers.
220, 230, and 240 are the result of wiring a transformer in a delta configuration resulting in additive voltage of any single line to ground.
What all this means 220, 230, 240 wiring will all be the same, for 208, a dedicated motor is the proper solution but it will run on 220- etc.
You may need your spectacles and a magnifying glass to see the delineation on the terminals often they are just proud spots on the plastic insulator and hard to make out.
As to the cord ends ensure you have the proper cord end for the voltage you are working on!! you may have to change the receptacle to get it right but simply rewiring with the cord ends for a different voltage is a recipe for disaster. 115 equipment will not survive a test run at 220, and 220 left plugged into a 115 outlet will die over a few minutes, or repeatedly pop the breaker.
Nothing is foolproof to a sufficiently patient fool!
