Nominal speed is no longer the speed previously agreed on in the supply contract, but typically a deviating, rounded, and generally applicable speed such as 2,900, 1,450, or 980 min–1 (rpm) for a mains frequency of 50 Hz or 3,500, 1,750, 1,180 min–1 (rpm) at 60 Hz.Jul 20, 2016 read more
Nominal speed Nominal speed (nN) is a suitable, rounded speed value for classifying the speed range (see Nominal value). Nominal speed is no longer the speed previously agreed on in the supply contract, but typically a deviating, rounded, and generally applicable speed such as 2,900, 1,450, or 980 min–1 (rpm) for a mains frequency of 50 Hz or 3,500, 1,750, 1,180 min–1 (rpm) at 60 Hz. read more
Nominal speed is given at 5000 RPM. I have a voltage induced due to the prime mover of 494 V. Nominal voltage of the generator is 460 V. According to my textbook, I have to calculate idle speed out of those three values. read more
For example, a pump is designed to deliver its nominal pressure and flow while operating at its nominal speed and power. Actual operating conditions may vary. NiMH and NiCd rechargeable batteries have a nominal voltage of 1.2 V, but will actually supply real voltages ranging from about 1.45 V to 1.0 V during discharge. read more
