Industrial sewing machines are amazing, but 10,000 stitches per minute (yes, you read that right) was much more than I could handle. At a fraction of the size of a clutch-style motor It is better balanced, quieter and more easily controlled.On my industrial serger torque isn't a concern, but speed is. However, on my walking foot booth are concerns. At all speeds, but especially low speeds, the torque is vastly improved. I can punch thru nearly anything that I can fit under the foot.The best upgrade I've made for perhaps anything I've ever owned. That is saying a lot, I'm an old guy who has been upgrading stuff since adding RAM to my Atari 400 in the 80's.
