Calculation of Current Unbalance Factor for Induction Motor under the Unbalanced Voltages

불평형 전압 인가시 유도전동기 전류 불평형율 계산

The current unbalance occurs in an induction motor with the supply of unbalanced voltage. Existence of an current unbalance occurs by various problems at the time of driving by in crease of the noise not to mention output decrease of a motor by increase of a loss. We confirmed how current unbalance occurred by a voltage unbalance because a slip came to change by the driving situation of a subordinate as for the induction motor. We confirmed that case to run to a low slip in a ratio of the same voltage unbalance rate brought a high current unbalance rate.
