AC drives are employed mainly in process plants for various applications. In most industrial applications, Induction motor preferred as they robust, reliable, and efficient. Process industries have seen a paradigm shift from manual control to automatic control. Advancements power electronics technology led smooth of the induction using variable frequency over an entire speed range. Variable Fre...

Abstract Agriculture is a socially significant sector of the economy. The growth agricultural production contributes to stable development society. It necessary use new mechanisms driven by induction motors increase productivity. Three-phase are mainly used in electric drive machines. At same time, it advisable single-phase network supply power remote farms. In this regard, using three-phase be...

In this study, the Axial Flux Synchronous Reluctance Motor (AF-SynRM) with multiple barriers in its rotor is designed and it aimed to compare performance Induction (AF-IM) same stator structure dimensions. For an equal comparison, motor dimensions are chosen same, only changed. preliminary study of designs, machine calculated analytically modeled 3D Finite Element Method (FEM). To optimize sali...

The outline design of a fully superconducting motor for liquid hydrogen pump with a magnesium-diboride (MgB2) superconducting wire is carried out to present various advantages arising from its prospective performances. The squirrel-cage rotor winding composed of superconducting loops with the MgB2 wire enables us to operate the motor not only in a slip mode but also in a synchronous rotation mo...

This paper describes discretized Extended Kalman Filter (EKF) for speed estimation of squirrel cage induction motor. Speed and rotor fluxes are estimated from the measured terminal voltages and currents without anymore additional filter. There is a mathematical basis that yields excellent simulation and real time results. In this, speed is considered as a parameter and state. The speed of an in...

Effective condition monitoring of induction motors requires knowledge of the number of rotor slots and the rotor speed. These were primarily obtained in the literature by multiple measurements and using design knowledge of the motor under test. Furthermore, the earlier studies have mainly concentrated on stator current analysis. This paper investigates the use of the stator current, axial flux,...
