The Effect of Unbalance Supply on the Three- Phase Synchronous Motor Performance in the Laboratory

Abstract

A detrimental worldwide phenomena that affects the output of three-phase synchronous motors is voltage unbalance. There are several ways that a three-phase source voltage can become unbalanced. A motor may be practically impacted by imbalanced instances that vary in several ranges. The goal of this work is to assess the operations using relevant hypotheses. To understand the degree of such modifications, this paper examines balanced and imbalanced situations practically in relation to their mechanical and electrical performance. This performance entails the currents of stator, total harmonics distortion, the speed of the motor, and the efficiency. The experiment was conduct laboratory on three phase synchronous motor.
