Induction motor variable inductance parameter identification
2017 International Conference on Smart Systems and Technologies (SST), 2017Paper derives a procedure of identifying induction machine variable inductance values. Parameter identification is done from measurements during no-load direct start acceleration. Genetic algorithm is used for parameter identification. It is used to minimise least squares difference between calculated and measured data by selecting parameters of ...

Markov analysis of an induction motor
2016 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2016The paper deals with the reliability of induction motors by using Markov techniques. The basis of this process is to perform the reliability predictions to obtain the necessary indicators in order to support the Markov analysis. The analysis is made on a single-phase induction motor, taking into consideration the most critical components that could ...

Harmonic Analysis for Induction Motors
2006 Canadian Conference on Electrical and Computer Engineering, 2006Two types of harmonics are investigated for induction motors: space harmonics and time harmonics. Space harmonics are generated due to the different phase windings interaction when the power supply is sinusoidal and they can be reduced by applying a proper machine design.

European Journal of Physics, 2015
Summary: We obtain analytical expressions for the torques and angular speed of an induction motor with a simple geometry, resembling the geometry of the first induction motor investigated by Arago in 1824. The rotor is a conducting disc rotating between the magnetic poles of two off-axis solenoids, displaced in space by 90\(^\circ\) from each other. We

On speed control of induction motors
Proceedings of 1995 American Control Conference - ACC'95, 1996Espinosa and Ortega (1994) presented an output feedback globally stable speed tracking controller for induction motors. An important feature of the scheme is that it does not require state observers, thus reducing the computational burden, a critical limiting factor in physical implementations.

Induction motors on unbalanced voltages
Electrical Engineering, 1936Characteristics of polyphase induction motors are analyzed in this paper by the method of symmetrical components in a manner different from other recently published articles. The analysis is neither tedious nor highly involved and curves of motor characteristics obtained by tests under unbalanced conditions agree closely with curves obtained by ...

Motion control with induction motors
Proceedings of the IEEE, 1994Induction motors (IM) provide a very wide speed range, mechanically robust and relatively low cost motion control option. An up-to-date summary of the status of induction motor motion control technology is the subject of this paper. The topics which this paper includes are as follows: basic motion control system requirements; field orientation ...

Induction Motor Control Design
2010Nonlinear and Adaptive Control Design for Induction Motors is a unified exposition of the most important steps and concerns in the design of estimation and control algorithms for induction motors. A single notation and modern nonlinear control terminology is used to make the book accessible to readers who are not experts in electric motors at the same ...

THE MAGNETOSTRICTION FORCES IN THE INDUCTION MOTOR
COMPEL - The international journal for computation and mathematics in electrical and electronic engineering, 1995The paper describes how the classical formula of the Maxwell magnetic stress tensor may be extended to cover the magnetostriction phenomena. It is assumed that the ferromagnetic continuum is isotropic and conservative. The method takes into account the magnetic nonlinearity and it assumes that mechanical deflections are sufficiently small to neglect ...

The Single-Phase Induction Motor
Transactions of the American Institute of Electrical Engineers, 1925The operation of the single-phase induction motor is presented according to the cross-field theory as distinguished from the theory of oppositely rotating fields. The mathematics used require only a knowledge of algebra and trigonometry and no factors, such as cross-field iron loss and cross-field magnetizing current, are neglected.
