The performance of a voltage-controlled large induction motor soft starter has been improved, resulting in nearly perfect current and torque profiles. The performance analysis of the soft-starter motor-load combination has been carried out in the dynamic state using a hybrid induction machine model which takes account of disconnected two-phase and three-phase operational modes of the machine. Some simple control strategies have been proposed to keep the current constant at any preset value during starting, and to eliminate supply-frequency starting torque pulsations. These are shown to be very effective in the elimination of reclosing transient torque and current components at any speed at the reconnection instant to the supply after an interruption, or at the instant of bus transfer. The proposed strategies have been verified experimentally on a laboratory machine using a special torque measurement system in the dynamic state.

Soft starting of large induction motors at constant current with minimised starting torque pulsations Zenginobuz, G; Cadirci, I; Ermiş, Muammer; Barlak, C (2000-10-12) The performance of a voltage-controlled, large induction motor soft starter has been improved, resulting in nearly perfect current and torque profiles. The performance analysis of the soft starter, motor - load combination has been carried out in dynamic state using a hybrid induction machine model which takes account of disconnected, two-phase and three-phase operational modes of the machine. Some simple control strategies have been proposed to keep the current constant at any preset value during starting,...
A Novel Noise Reduction Technology for Switched Reluctance Motors Bizkevelci, Erdal; Özlü Ertan, Hatice Gülçin; Leblebicioğlu, Mehmet Kemal (2008-07-24) The conditions are sought at which an SIR motor can be operated with highest efficiency, while producing a desired torque output at low shaft torque ripple. The investigation is based on the simulation software that uses measured flux-linkage (V, 0, 1) and static torque (T, 0, 1) characteristics of a given motor. The variation of the shaft torque, torque ripple and efficiency of the motor Is investigated, while the control variables "advance angle" and "conduction angle" are swept over their range with a co...
Wide-Speed Range Control Strategy for a 8/6 Switched Reluctance Machine Pop, A. C.; Petrus, V.; Martis, C. S.; Iancu, V.; Gyselinck, J. (2011-09-10) A control scheme for obtaining low torque ripple and high efficiency for a minimal reduction in average torque as compared to its maximal value is presented for a four-phase switched reluctance motor. At low speed, the torque ripple is minimized by the means of current profiling techniques. As the speed increases the controller switches to optimal firing angle control strategy. The optimal values for the angles are obtained based on minimization routine for different objective functions. Starting from the o...
Calculation of core losses of a six-phase induction motor with third harmonic current injection Büyükbaş, Afşin; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2004) The advantages of using a six-phase induction motor for industrial drives, over the conventional three-phase drive can be summarized as improved reliability, reduction on the power ratings for the static converters and harmonic reduction. A technique of injecting third harmonic zero sequence current components in the phase currents to improve the machine torque density was presented recently by another research study. However, to meaninigfully evaluate the performnce of such machines and/or to be able to ma...
Control of BLDC Motor in Presence of Static Rotor Eccentricity Shakouhi, S. Mohammad; Mohamadian, Mustafa; Afjei, S. Ebrahim (2011-09-10) BLDC motors are one of the motor types rapidly gaining popularity. In recent years various researches have been done in the field of motor fault detection and fault tolerant control. However, in the case of rotor problems, especially rotor eccentricity tolerant control a few papers have been presented. Since in sensitive industries, continuous operation with good performance till the maintenance time is very important, operating in the desired condition in presence of this kind of fault is really advantageo...
