Mike, One problem I see with your drawing is that L2 constantly supplies power to the motor. I am good with single phase wiring but 3 phase I havent done much only a few car lifts, compressors, tire machines. Here is a picture gallery about three phase contactor wiring diagram complete with the description of the image, please find the image you need. Some small motors have that built-in to the motor itself. His motor is similar to the one you show except the start switch is connected to the start Cap and allows current to flow thru the run cap.

But i love my readers, as i am a student and struggling- for learning. We start by bringing in the 2 power leads to L1 and L2 on the contactor. It will draw very little current. The classic method of reversing a three-phase motor is a mechanically interlocked pair of three pole contactors.
If this is the case, then one can use two poles on a three pole disconnect or drum switch to provide the incoming 240 volt line. Here I have shown the forward reverse motor control diagram for 3 phase motor. Now if you have any question and have any suggestion then you can use the below comments box.

In a single phase 110 device, it might be ok to break the live pole and leave the neutral connected. Thanx Sikandar for the valuable information.
Because the other end of the start circuit is tied to the centertap on the run winding, it effectively swaps the current direction in the start winding. This is how Springer Controls does it in our. Quite glad I did so. I also published post about motor starter working you can see on below links. Many people looking for info about three phase contactor wiring diagram and definitely one of these is you, is not it? I just got carried away re greasing.
