Experimental results from a frame size 180 brushless doubly fed (induction) machine (BDFM) fitted with four rotor designs are presented. The machine is intended for use as a variable speed generator, or drive. A per phase equivalent circuit for the machine has been developed and a method of obtaining parameters for the circuit is described. Expressions for the torque as a function of speed have...

In order to reduce the costs of implementing radial position control system a three-phase bearingless machine with split winding, this article proposes driving method that uses only two phases instead traditional one. It reduces from six four number inverter legs, drivers, sensors, and current controllers necessary drive system. To justify proposal, new power configuration was applied 250 W con...

Due to simplicity, efficiency, and the ability accommodate energy storage devices, DC distribution networks have been seen as an optimal alternative AC networks, especially aboard future electric ships. The emerging system entails new control management techniques. Therefore, integrated power network ship is selected case study in this paper. To meet requirements of such a large-scale mobile sy...

The use of mechanical energy in daily life including industries and transport applications are increasing rapidly. Induction motor has special advantages because less cost, reliable, robust maintenance when compared to other motors. It also features which satisfies all the requirements. On whole 3-phase IM (Induction motor) plays major role several (i.e. industrial, mechanical). meticulous beha...

Three phase induction machines for traction applications in electric and hybrid electric vehicles can be used with a fixed gear due to the wide speed range enabled by field weakening. Although the induction machine is know as an extremely reliable and robust device, machine faults may occur. Machine faults which do not become detected may cause complete failure of the vehicle. Therefore, early ...

ABSTRACT The single-phase induction motor, in permanent split capacitor topology, is used in some models of washing machines. This paper presents the implementation of the cycloconverter control to drive the washing machine in order to provide benefits in improving the energy efficiency and the motor drive. The results obtained from the experimental setup showed good advantages in the dynamic r...

The main advantages of multi-winding (multiphase) induction machines include reducing torque ripple, decreasing rotor harmonics losses, the current per phase without increasing voltage phase, DC source, and high fault tolerance. authors propose a theoretical description for harmonic content DC-link current, magnetomotive force, electromagnetic machine (IM), an account interaction time power sup...

This work suggests a dual three-phase Space Vector Modulation (SVM) for the Diode Clamped Multilevel Inverter (DCMI) to ensure robust control of Dual Star Induction Motor (DSIM). The principal scheme is investigated apply same six-phase multilevel inverter by two drive DSIM. use classic SVM offers significant simplifications controlling six phase five levels inverter. proposed approach employs ...

Abstract – This paper suggests the techniques in determining the values of the steady-state equivalent circuit parameters of a three-phase induction machine using genetic algorithm. The parameter estimation procedure is based on the steady-state phase current versus slip and input power versus slip characteristics. The propose estimation algorithm is of non-linear kind based on selection in gen...
