The original motor is very loud and vibrated after 1 month it went to south. The new motor sounds much better and it is running very smooth.Motor on mine shook and vibrated from day 1 (same 1440gt). Made the whole lathe vibrate. I took it off and ran it by itself and it was definitely the motor. They replaced mine with the Baldor as well and the whole lathe is exceptional now. Like 10/10 exceptional. Zero regrets ponying up for the Taiwanese machine after motor was replaced.
