tailieunhanh - Notes For An Introductory Course On Electrical Machines And Drives

The purpose of these notes is be used to introduce Electrical Engineering students to Electrical Machines, Power Electronics and Electrical Drives. They are primarily to serve our students at MSU: they come to the course on Energy Conversion and Power Electronics with a solid background in Electric Circuits and Electromagnetics, and many want to acquire a basic working knowledge of the material, but plan a career in a different area (venturing as far as computer or mechanical engineering). Other students are interested in continuing in the study of electrical machines and drives, power electronics or power systems, and plan to take further courses in the field | Notes for an Introductory Course On Electrical Machines and Drives MSU Electrical Machines and Drives Laboratory Contents Preface ix 1 Three Phase Circuits and Power 1 Electric Power with steady state sinusoidal quantities 1 Solving 1-phase problems 5 Three-phase Balanced Systems 6 Calculations in three-phase systems 9 2 Magnetics 15 Introduction 15 The Governing Equations 15 Saturation and Hysteresis 19 Permanent Magnets 21 Faraday s Law 22 Eddy Currents and Eddy Current Losses 25 Torque and Force 27 3 Transformers 29 Description 29 The Ideal Transformer 30 Equivalent Circuit 32 Losses and Ratings 36 Per-unit System 37
