Morning all,
We switched from using the traditional DT/DV motors with the new ones (DR). But we are experiencing higher currents. We tried two scenarios:
1- Direct connection to power lines, with no load, currents close to the rated...
2-With VFD, when we go low with frequency to around 15Hz, the currents exceed the nominal and still, the motor is running with no loads.
We used to use motors of the same size, with the same VFD (old DT/DV), the currents where much lower...
Anyone experiencing such behavior with SEW DR motors?
PS: It's not just one motor, we tested several motors.
I thank you in advance,
