First post, found this site looking for info on a vfd, my question is can a vfd speed up, say for instance a 1725 motor to higher rpm's?
Thanks

 

Yes, a VFD can raise a motor rpm higher than the nameplate. However you can only go so far, the more above nameplate speed the more torque decreases.

 

You really need to get a good spec sheet for the motor. The VFD will likely try to increase voltage proportionally with frequency, so you need to be sure the motor can take it. The nameplate will provide nominal values but won't usually tell you the max voltage/frequency it can handle.

 

Yes, a VFD (Variable Frequency Drive) can increase the speed of a 1725 RPM motor by adjusting the frequency of the power supplied to the motor. However, keep in mind that there are limitations to how high the speed can go without affecting the motor's performance or lifespan. Always check the motor’s specifications for maximum safe RPM.

Generally the maximum voltage the VFD can output is the line voltage and the motor would be rated for that, maximum frequency should be checked.
