2960rpm motor at 3800 rpm
2960rpm motor at 3800 rpm
(OP)
We Use 2960 rpm Motor(50Hz) to operate at 3800 rpm.
I apply VVVF(Inverter) on Motor(50HZ cetrifugal Motor) of multistage volute Pump in R/O Desalination Facility.
To get Performance of Pump, We must apply 63 Hz to 50 Hz Motor.
Operating RPM is higher than RPM on Motor Nameplate.
( rpm of 50 Hz motor : 2960 / Real Operating rpm of motor : about 3800)
I want to know problem in that operating condition.
Plaese, reply my question. thanks for your attention.

Running at 63hz should cause no problems to your motor, as far as the bearings go..It will obviously shorten the regreasing intervals if this is done,,or the bearing life!!
This said..you must make sure that running the pump that much faster isnt going to overload the motor!!

I have not had experience with such a large change in RPM from nameplate ratings but I know I would be contacting the manufacturer on this one to get their input.
