trying to understand torque.
thought it was the vfd. it was a two speed motor. torque seems to be more a product of the motor instead of the vfd.
When I hooked it up to low speed, it didn't stall at 22rpm at the saw blade. 30:1 gear box ratio. aka 44hz.
wired at high speed, 22rpm at saw blade is 22hz and stalls.
customer wants to run saw at 10rpm, but it stalls. He still thinks it the vfd. I think it the motor, but think he may be partially correct.
the vfd set to constant torque. the vfd is a 10hp vfd. the motor is 3.5hp. so the vfd should be more than capable. have the cli turn up to 20amps. and the torque boost maxed out.
