The Effect of Steel-Core Choke on the Performance of a Single-Phase Universal Motor

Abstract

This study presents a robust robotic system designed to automate the feeding of lightweight components into appropriate machining centers. These centers utilize single-phase handheld power tools, each equipped with specific cutting implements and powered by a single-phase universal motor with rated power of 1.125 kW operating on AC voltage. A notable characteristic of these universal motors is their power supply through a three-phase converter. The research proposes an experimental methodology to evaluate the impact of incorporating a steel core choke on the performance of each universal motor. An inductance, with specific parameters of 2.32 mH, is connected between the three-phase converter and the single-phase universal motor. This inductance also functions as a positive current feedback mechanism. The system's robustness is enhanced through current and voltage feedback connections to and from the single-phase universal motors, improving the control of each universal electric motor.
