Reliability Comparison Between Standard and High Efficiency Induction Motor Using Vector Control Method

Abstract

Recently, the induction motor comprises the majority of all motors utilized in machinery, and the operating efficiencies of these machines greatly impact the overall energy consumption in industry. Current motors are produced with higher efficiency ratings than standard motors, but the decision to replace an existing motor focuses on the actual cost savings that depend on several key points such as operating efficiency, percentage of time at given loads. Owing to the importance of induction motors, this work investigates vector control of a high efficiency induction motor (HEM). Most papers related to control concentrate on flux oriented for solving the problem of voltage and power limitations of two-level inverters. A simulation model is implemented to compare the performance of the first and the second motor. The comparison includes speed performance, torque and current. Through which finally we can declare that, they found results are satisfactory.
