This book was released on 2003-09-30 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modeling of Induction Motors with One and Two Degrees of Mechanical Freedom presents the mathematical model of induction motors with two degrees of mechanical freedom (IM-2DMF), formed in the electromagnetic field as well as in circuit theory, which allows analyzing the performance of these three groups of motors taking into account edge effects, winding and current asymmetry. The model derived is based on the concept of magnetic field wave moving in the air-gap with a helical motion. In general, the rotor moves helically too with the rotary-linear slip. The electromagnetic field as well as motor performance of the particular motors is analyzed. The mathematical model of IM-2DMF is more general to the model of induction motors with one degree of mechanical freedom, i.e. rotary and linear motors. Examples of modeling two types of rotary disc motors and flat linear motor with twisted primary part are presented with inclusion of finite stator and rotor length and width effects. The simulation results are backed by the measurements carried out on the laboratory models, which were tested on the unique measurement stand.

This book was released on 2023-07-21 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is a compilation of knowledge about computer models in the three-phase stator reference frame. Chapters explore several aspects of the topic and build upon research previously presented by contributors. The book aims to provide interesting solutions to problems encountered in the design of railway and analysis in railway motors. The modeling approaches proposed by the authors in this book may become an incentive for readers and researchers to develop their ‘lifehacks’ to solve new problems in induction motor design and testing. Key topics presented in the book: - Approximate calculations of induction motor equivalent T-shaped circuit parameters with the use of catalogue data - Simulations of different types of shaft load, including fluid coupling - Receiving static characteristics of an electric machine during simulation by means of dynamic model - Simulation of the electric drive’s specific applications with three-phase induction motors building - Direct start of an induction motor as part of an auxiliary drive of an AC electric locomotive, containing a capacitor phase splitter, starting with different types of shaft loads (fan or compressor). Special attention has been given to the description of the thermal model of an induction motor with a squirrel-cage rotor, which makes it possible to simulate operating modes when powered by an unbalanced voltage, as well as with squirrel cage defects. The thermal model is presented as a detailed superstructure to the model of electromechanical processes of an induction electric machine. Other key features of the book include references for further reading, an appendix for the parameters of the equivalent thermal circuit of an NVA-55 induction motor. The material presented in the book is of interest to railway motor engineers, specialists in electromechanics and electric drives who use SPICE-compatible CAD applications in their work.

Available in PDF, EPUB and Kindle. Book excerpt: Thermal modeling is an important aspect of electric motor design. Numerous techniques exist to predict the temperatures in a motor, and they can be incorporated in the design of a thermal model for a new type of electric motor. This work discusses the available modeling techniques and determines which methods are applicable for medium-sized motors with either natural convection or forced convective cooling over irregular geometry. A time-dependant thermal model, with thermal transport parameters based upon geometric and simplified air flow information, is developed based on a discrete lumped parameter model with several modifications to improve accuracy. The model was completed with the aid of nine experiments, and the result is a thermal model that exhibits an absolute error of less than 6.1°C for the nine test runs at three different currents between 8.4 A rms and 28.2 A rms and three cooling levels, natural, 10.7 CFM and 24.4 CFM.

Download or read book Thermal Response in a Field Oriented Controlled Three-phase Induction Motor written by Niyem Mawenbe Bawana and published by . This book was released on 2019 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research conducted at the department of Electrical Engineering of the University of South Florida campus in Tampa only covers the electrical aspect of electric drives. However, the performance of electric machinery is significantly impacted by temperature variation. The literature review shows three main control techniques in use today in electric drives namely, Scalar control, Direct Torque control and Field Oriented control. This thesis presents a temperature rise of rotor bars, stator winding, stator core and stator frame in a running three phase field-oriented controlled induction machine. A literature search shows that none of research has been carried out to investigate a thermal response of a field-oriented controlled induction motor. With this motivation, we were able to implement a lumped parameters thermal model of a three-phase field-oriented IM in MATLAB Simulink, which allows us to determine that rotor bars have the highest temperatures rising to 84 degrees Celsius. This confirms that rotors bars are the hottest part of a running IM as stipulated in literature.
