Brad – Thanks so much for the input. The FM50-101 looks like a good solution. With that said, what other components would I need to complete the electrical portion of the swap? You mentioned a starter…do you have any recommendstions? If I were to go this route, is it as simple as wiring the motor to the VFD, and then wiring that to the starter, or is there more to it than that? Are there any references you can point me to that might illustrate the process?

No.. you rip the starter out that is on there now (last two of your pictures above). The VFD provides the motor control and overload protection, so the starter is not used or needed. Couldn’t be easier, and the hardest part is trying to figure out where to mount the VFD. Only other thing required would be some wire and a plug for the wall (eg: an extension cord with the socket part cut off :)

Finally, you mentioned the need to upgrade the electrical for a motor swap. Any chance you could point me in the right direction?

The starter is a safety device… it has a magnetic contactor in it that will prevent the machine from coming back on after a power fail, and provides overload protection to the specific motor it is configured for. Change the motor, and you need to change the starters overload capability – there is a list on the data sheet you pictured above, which specifies what heater(s) you need for specific amperages. Try reading this primer over at the VM site: Magnetic Starters
One other alternative would be to get rid of the existing starter and get a cheaper IEC type starter, which has what I like to call ‘dial-a-amp’ :) Although that would bump up costs a lot more and be inferior to what you have now.
