In 1974 Blaschke and Hasse introduced the so called eld-oriented method for the control of induction motors [1, 5]. This method is based on a nonlinear coordinate change, admitting a clear physical interpretation since corresponding to a rotation by the rotor ux angle. In these coordinates the equations of the induction motor are very similar to the equations of a DC motor. Since the control of...

Since the linear induction motor commonly work with a laterally asymmetric secondary as it is applied to pull rail vehicles, this paper presents complete equivalent circuit model considering asymmetry predict thrust, vertical and transversal forces. First, six correction factors are presented quantify variations in air-gap magnetic flux induced current operating secondary. Second, develops base...

This paper presents a parametric low differential order model, suitable for mathematically analysis for Induction Machines with faulty stator. An adaptive Kalman filter is proposed for recursively estimating the states and parameters of continuous–time model with discrete measurements for fault detection ends. Typical motor faults as interturn short circuit and increased winding resistance ...

India's power sector is facing an actuate problem of meeting the growing demand electricity. Improving energy efficiency by employing efficient devices would be better alternative for apart new demand. The use motor instead standard induction in agricultural and industrial sector. It will result into substantial saving electrical over a motor. effort taken introduced this paper analyze addition...
