This paper presents an air-gap torque (AGT)-based method for efficiency estimation of induction motors. A new concept of stator resistance that includes the mechanical losses effect is proposed. This new stator resistance is estimated through a particle swarm optimization approach based on the stator flux equations and minimization of torque error at the rated operation point. Then, the obtained stator resistance is used in the AGT equations to estimate the shaft torque and then the efficiency. Moreover, the rotor speed is estimated using induction motor current signature analysis. Thus, the proposed methodology for induction motor efficiency estimation relies only on line currents, line voltages, and nameplate data, being appropriate for in-service applications. Finally, the simulation and experimental results are presented to validate the proposed method at different load conditions.

“…Eccentricity related faults in rotor cause a consistent air gap that corresponding the unbalanced magnetic force and non-consistent air gap magnetic field which producing the vibration and noise on stator [47][48][49]. Most of the research [50][51][52][53][54] has been published in last years about the vibration and noise on Permanent magnet synchronous (PMS) and DC motors but little research has been done on the eccentricity related fault in rotor to observe the vibroacoustic behavior of IM motors.…”

“…These parameter changes depend upon the severity of the fault and interaction with other parameters. A broad range of survey [34][35][36][37][38][39][40][41][42][43][44] has been done from different researchers and many techniques (e. g. thermal monitoring [50,51], current analysis [47,48], torque monitoring [54,55], noise monitoring [52,53] and vibration analysis [49]) for fault detections has been investigated, but all other techniques except MCSA are required some expensive sensors for monitoring machine condition [20,45]. This is the reason the current monitoring techniques is non-intrusive and also may use for the remote monitoring in the central motor control center.…”

Machine fault diagnosis is a very important topic in industrial systems and deserves further consideration in view of the growing complexity and performance requirements of modern machinery. Currently, manufacturing companies and researchers are making a great attempt to implement efficient fault diagnosis tools. The signal processing is a key step for the machine condition monitoring in complex industrial rotating electrical machines. A number of signal processing techniques have been reported from last two decades conventionally and effectively applied on different rotating machines. Induction motor is the one of widely used in various industrial applications due to small size, low cost and operation with existing power supply. Faults and failure of the induction machine in industry can be the cause of loss of throughput and significant financial losses. As compared with the other faults with the broken rotor bar, it has significant importance because of severity which leads to a serious breakdown of motor. Detection of rotor failure has become significant fault but difficult task in machine fault diagnosis. The aim of this paper is indented to summarizes the fault diagnosis techniques with the purpose of the broken rotor bar fault detection. Keywords: machine fault diagnosis, signal processing technique, induction motor, condition monitoring.

“…Because of the previously mentioned facts, several efficiency estimation methods for in-service induction motors have been proposed. For instance, there are methods based on induction motor slip [7,12], current [13], equivalent circuit [14,15], and air-gap torque [1,[16][17][18][19]. Some of these methods are approached in this work and are explained in the following paragraphs.…”

Induction motors consume a great portion of the generated electrical energy. Moreover, most of them work at underloaded conditions, so they have low efficiencies and waste a lot of energy. Because of this, the efficiency estimation of in-service induction motors is a matter of great importance. This efficiency estimation is usually performed through indirect methods, which do not require invasive measurements of torque or speed. One of these methods is the modified Air-Gap Torque (AGT) method, which only requires voltage and current data, the stator resistance value, and the mechanical losses. This paper approaches the computation of a modified stator resistance including the mechanical losses effect to be applied in the AGT method for torque and efficiency estimation of induction motors. Some improvements are proposed in the computation of this resistance by using a direct method, as well as the possibility to estimate this parameter directly from the nameplate data of the induction motor. The proposed methodology only relies on line voltages, currents, and nameplate data and is not intrusive. The proposed methodology is analyzed through simulation and validated through experimental results with three-phase induction motors. Also, a comparison of methods for in-service induction motors efficiency estimation is presented for the tested motors.
