About the 100FN4031
100FN4031 is a base 460 VAC drive that is manufactured by Reliance Electric as part of their FlexPak 3000 series. Using the conversion kit model number 916FK0200, this drive can be converted into the equivalent 230 VAC drive model number 50FN20xx. This drive is non-regenerative and has a horsepower rating of 100 HP. The full load RMS AC line current is 154, and the full load rated DC armature current is 180. The rated field current is 15.
The speed regulation of this drive is 0.01% with a digital encoder. With an analog tachometer, the speed regulation is 1.0%. With armature voltage feedback, the speed regulation is 2.0%. The operating speed range is 1% to the rated speed, which is dependent on the top speed and the digital encoder used. For the speed range, the typical quoted regulation is 200:1. The continuous speed range for force-ventilated motors is 100% of the rated torque down to 5% of the base speed. The service factor capacity is 1.0, and the maximum load is 150% for one minute.
The displacement power factor at the maximum speed is 88.0%. The power module efficiency at 100% speed and 100% load is 99.3%. The power module efficiency at 100% speed and 25% load is 98.5%. The power module efficiency at 25% speed and 100% load is 96.8%. The power module efficiency at 25% speed and 25% load is 94.0%. The drive efficiency with the motor is typically 87.0%.
