Multiphase induction machine modelling represents a crucial research topic for both control and performance evaluation purposes. Generally, multiphase machines are preferably modelled using the vector space decomposition technique with some assumptions to simplify mathematical model. However, different sources of non-linearities, including low order harmonics mapped secondary subspaces, cross-c...

This paper presents a VHDL design and an FPGA implementation of direct torque controller (DTC) used to order induction machines (IM). The use at high sampling frequency reduces the ripple while maintaining classical DTC control structure. We have adopted modular approach, by dividing global entity into set elementary blocks designed implemented separately. performances this command are reduce 0...

This paper presents a physical model of a squirrel cage induction machine with rotor topology. The machine is modeled in Modelica, an object oriented multi physical modeling system. The presented machine model is used to investigate electrical rotor asymmetries in induction machines. For the case of a single broken rotor bar a simulation model is compared with measurement results.

Condition monitoring and fault diagnosis of engineering plant has increased recently because of the widespread use of automation and consequent reduction in direct human-machine interaction to supervise the motor drive system operation. With advances in digital technology in recent years, adequate data processing capability is now available on cost-effective hardware platforms, to monitor motor...

This presentation will be a broad survey of progress in induction technology over the past four years. Much work has been done on accelerators for hydrodynamic test radiography and other applications. Solid-state pulsers have been developed which can provide unprecedented flexibility and precision in pulse format and accelerating voltage for both ion and electron induction machines. Induction l...

The purpose of this work is to determine the values electrical parameters synchronous and induction machines validate interactions between an generator a generator. generators are connected in two ways: (i) isolated from common bus (ii) parallel steady state, subject nonlinear load. They old refurbished machines; thus, parametric regression methodology used parameter values. After computational...
