www.nrel.govA significant fraction of the electricity is consumed by medium-voltage, high -power electric motor drives, which are used in chemical, oil, gas, mining, and manufacturing industries (Wolk 2014). Medium-voltage motor drives are usually defined as those with voltages between 2 kilovolts (kV) and 15 kV and powers between 0.2 megawatt and 40 ...

library.e.abb.comVoltage reflections and common mode voltages, caused by any inverter topology, are a real concern for medium voltage motors. They cause excessive stress to a standard motor insulation and create harmful bearing currents, both with potentially disastrous consequences. Furthermore, the motor is subjected to additional harmonic heating generated ...

controltrends.orgVariable speed AC drives will maintain a constant volts/hertz relationship from 0 - 60 Hertz. For a 460 motor this ratio is 7.6 volts/Hz. To calculate this ratio divide the motor voltage by 60 Hz. At low frequencies the volt-age will be low, as the frequency increases the voltage will increase. (Note: this ratio may be varied somewhat
THE FUNDAMENTALS OF AC ELECTRIC INDUCTION MOTOR …
www.enginuitysystems.com208-230/460 V motor will have degraded performance at 208 V. Another common misconception is to request a motor rated at network voltage, for example, at 480 V. The NEMA standard is 460 V. The voltage rating assumes that there is voltage drop from the network to the motor terminals. Thus, the 460 V motor is appropriate on a 480 V network.

www.rockymountainbaldor.comFor example, a motor with a 1.0 service factor cannot be expected to handle more than its nameplate hp on a continuous basis. A motor with a 1.15 service factor can be expected to safely handle infrequent loads to 15% past it’s rated horsepower. A 10 hp motor could run at 11.5hp. A downside is a hot motor with a shorter expected life
