Al yours are good questions, better to ask then fry something. The Transformer obviously needs to be rated higher power then the power drawn by the motor. Due to Power Factor VA instead of Watts is often labeled but regardless due to heat losses and inefficiency so long as the transformer is rated say at least 15% to 20% higher then your motor at full load, you should be fine. Your transformer is likely an isolation transformer NOT an Auto Transformer but should work as you have indicated as step down or step up.
Best I recall but its been yearssssssssss lol: You first compute the Maximum Continuous Current,,,,,,,,Size the conductors to have a Minimum ampacity of 125% of the MCC, size the overcurrent protection to protect the conductors, provide thermal overload protection for the motor. Back when and where I practiced a disconnect means was required within sight and within 50 feet and I often specified a Combination Starter which did BOTH.
I guess your motor isnt dual voltage (wiring diagram and number of wires under the cover is where to look) because it would be so much simpler grrrrrrrr

It was on one such Saturday in the early 1940's when Sam was 16 years old that he ended up in Dennison, Kansas to watch a demonstration of a new tractor being put on by a local dealer.
