just want to check if you guys would agree with this:
got a direct coupled centrifugal fan to a motor powered by a VFD.
fan rated speed is 1785 RPM and full load motor speed is 1775 rpm. Vendor says the torque produced by the fan at rated fan speed is much less than the motor's full load torque, so the motor will actually run at a higher speed than its full load speed of 1775 RPM.
is that accurate? do some of you guys have experience with this type of situation?
Thanks!
