An Improved Big Bang-Big Crunch Algorithm for Estimating Three-Phase Induction Motors Efficiency
Nowadays, the most generated electrical energy is consumed by three-phase induction motors. Thus, in order to carry out preventive measurements and maintenances and eventually employing high-efficiency motors, the efficiency evaluation of induction motors is vital. In this paper, a novel and efficient method based on Improved Big Bang-Big Crunch (I-BB-BC) Algorithm is presented for efficiency e...
متن کاملVibration and Current Monitoring for Fault’s Diagnosis of Induction Motors
In generally, detection and diagnosis of incipient faults is desirable for product quality assurance and improved operational efficiency of induction motors running off the power supply mains. In this paper, the vibration and current of an induction motor are analyzed in order to obtain information for the detection of bearing faults. Significant vibration and current spectrum differences betwe...
متن کاملModitication Factor for Sizing Equation of Electrical Machines-Single and Three Phase Induction Motors(RESEARCH NOTE)
Comparison between the results from the design procedure based upon the value of D2L (volume of iron) and IEC standard used by manufacturers indicates that the basic design equation of electrical machines must be modified by a proper modification factor. This modification factor is evaluated for single- and three-phase induction motors and its variation with motor rating and poles number is obt...
متن کاملEnvelope Analysis on Vibration Signals for Stator Winding Fault Early Detection in 3-Phase Induction Motors
This paper brings up a novel method for detecting induction motor stator winding faults at an early stage. The contribution of the work comes from the delicate handling of motor vibration by applying envelope analysis, which makes it possible to capture electrical short-circuit signature in mechanical signals, even if the magnitude of the fault is fairly incipient. Conventional induction motor ...
متن کاملDirect Torque Control Strategy for Dual Three Phase Induction Motors
In this paper, a comparison between a classic direct torque control (DTC) and a modified (DTC) of a dual three phase induction machine (SPIM) will be introduced. In this work, the SPIM has a dual three phase windings spatially shifted by θ electrical degree wich is equal to 60◦. SPIM drive has 64 inverter switching states which provide higher possibility in selecting space voltage vectors than ...
