that's a slow one. most standard motors are 1450 rpm only way to reduce it is a smaller pulley on the motor. that's providing the current one on isn't 2 small and u can reduce its sizeYeah plate says 380-440. Wouldn’t a single phase motor would run at higher rpm? the original motor runs at 950.
How much are they?Or get a vfd that steps up the voltage, so 240v in, 440v out. I have a couple of aliexpress.com ones
