Investigation of motor characteristics when connected to a Nola controller
Abstract
Tests performed on Nola-type power factor controllers for induction motors are described. The behavior and efficiency of representative controllers for motors of single phase fractional horsepower and three phase up to 25 horsepower were examined. In so far as possible, normal installation and operating conditions were simulated. The controllers were initially adjusted according to manufacturer's instructions and tests were run under various conditions of load and input voltage to determine their operating characteristics. Most of the controllers tested were purchased at random from representative manufacturers. However, during the period of the investigation, several manufacturers loaned controllers to the project to be tested. Some of the controllers operated reasonally well while others could not be stabilized at all. Operating data were included for those units which were stable and mention was made of those which were not.
