Most of rotor related faults in three-phase induction motors are due to broken rotor bars and end-ring defects. Nowadays Inductions motors are more frequently used with inverters which make the diagnosis process more complicated. Furthermore, some manufacturers of induction machines mount converters (i.e. rectifier and inverter) directly onto the machine, which makes the stator current unattainable for diagnosis. In order to overcome these drawbacks, the authors propose to analyze new motor fault signatures in the supply line current of the inverter. Experimental and simulation results show a total agreement and confirm the effectiveness of the present study.

Experimental investigation of shaft transducerless speed and position control of ac induction and interior permanent magnet motors Goksu, Omer; Hava, Ahmet Masum (2010-01-01) In order to drive AC motors with high efficiency and high motion performance, and to provide accurate speed/position control, motor shaft speed and/or position feedback is required. For this purpose, usually transducers (encoder, tachogenerator, resolver, etc.) are installed on the shaft. However, transducers are not preferred in most of the applications since they increase the cost and decrease the reliability of the drive due to their failure prone structure and connections. In such applications, the spee...
Design optimization of variable frequency driven three-phase induction motors Ertan, B; Leblebicioğlu, Mehmet Kemal; Simsir, B; Hamarat, S; Cekic, A; Pirgaip, M (1998-01-01) An approach to optimize the design of three-phase induction motors for a wide speed range drive is considered. Two operating points in the speed range are taken into consideration. The problem is handled as a constrained optimization problem. An accurate model for the motor in terms of its dimensions has been developed which predicts the motor performance based on about 60 parameters of motor geometry.
Development of a hybrid global optimization algorithm and its application to helicopter rotor structural optimization Bilen, Muhammed Emre; Özgüven, Hasan Nevzat; Department of Mechanical Engineering (2019) Helicopters are notorious for their high vibration levels and the rotor system are the main contributors to the problem. The rotor vibrations can be minimized by optimizing the rotor structure, which require time-consuming high-fidelity solution for vibration predictions. To solve this problem, an effective and efficient global search algorithm called Explorer-Settler Optimization algorithm is developed by combining the advantageous aspects of Particle Swarm Optimization and Nelder-Mead Optimization algorit...
Design, Development and Implementation of Sensorless Digital Control of an Electric Motorization Dida, Abdelkader Hadj; Bourahla, M.; Ertan, Hulusi Bülent; Benghanem, M. (2014-09-24) The most industrial applications use the variation of the torque, speed and/or position in process, for which extremely severe specifications are needed. In the field of the drive of the electric machines, the elimination of the mechanical speed sensor can present an economic interest and improve safety of operation. One thus tries to make fulfill the speed measurement by implementing in a Digital signal processor (DSP) an algorithm of speed estimation using the current and voltage acquisition. Those method...
Line Current Analysis for Bearing fault Detection In Induction Motors Using Hilbert Transform Phase Oumaamar, M. E. K.; Razik, H.; Rezzoug, A.; Khezzar, A. (2011-09-10) The present paper focuses by means of an experimental study, on the effect of a bearing fault on the stator current signatures in induction motors. The variation in the amplitude of the characteristic components is not so significant. For that and in order to depict the presence of the fault harmonic signatures, the authors used the phase analysis of Hilbert transform applied on the spectrum modulus of the line current.
