Three-phase induction motors are industry’s workhorses and widely used as electromechanical energy conversion devices. Although induction machines are considered relatively reliable and robust due to their simple design and well-developed manufacturing technologies, failures do occur and may severely disrupt industrial processes and even lead to disastrous accidents. To prevent these failure ha...

Indonesia is one of the developing countries in industrial sector. Many equipment that utilizes an electric motor to run system. In running system using motor, it necessary adjust speed as needed. The 3-phase induction type has a strong, inexpensive, and high-efficiency construction, so often used industry. However, setting torque not easy do. Setting frequency voltage can be done inverter, the...

This paper describes a new, generalized and efficient steadystate model for the performance analysis of isolated six-phase induction generators. The mathematical model is formed directly from the equivalent circuit of six-phase induction generator by nodal admittance method. The proposed model is very simple which completely avoids lengthy derivations of non linear equations. The model results ...

ABSTRACT In this paper, a novel vector controlled sixphase induction machine which is fed from six-phase matrix converter is proposed. Though the practical implementation of matrix converter to vector controlled three phase induction motors is limited and still under investigation due to switches devices implementation difficulties and complication of modulation technique and commutation contro...

Multiphase machines are often chosen due to their enhanced fault tolerance. Six-phase ones especially convenient because they may be fed by off-the-shelf three-phase converters. In particular, those with symmetrical windings offer superior postfault capabilities. On the other hand, estimation of stator resistance is important for purposes such as thermal monitoring and preserving control perfor...

Steady-state analysis of a three phase induction motor can be carried out by using computer simulation software such as MATLAB. From Simulink/Power system block set (PSB) library, the induction motor model can be effectively used to simulate the effects of DC resistance, no-load and blocked rotor tests. These tests are performed on a machine to estimate the values of stator and rotor resistance...

A new squirrel-cage rotor structure induction motor (IM) that has a auxiliary permanent magnet (PM) rotor and improved cage-rotor structure is presented to enhance the inherent power factor of the IM, and a prototype motor is fabricated by modifying the rotor of a conventional three-phase four-pole squirrel-cage induction motor. The flux linkage, flux distribution, power factor, core loss and e...
