Induction Machines Handbook: Transients, Control Principles, Design and Testing presents a practical up-to-date treatment of intricate issues with induction machines (IM) required for design and testing in both rather constant- and variable-speed (with power electronics) drives. It contains ready-to-use industrial design and testing knowledge, with numerous case studies to facilitate a thorough assimilation of new knowledge.

Individual Chapters 1 through 14 discuss in detail the following:

• Three- and multiphase IM transients
• Single-phase source IM transients
• Super-high-frequency models and behavior of IM
• Motor specifications and design principles
• IM design below 100 kW and constant V1 and f1
• IM design above 100 kW and constant V1 and f1
• IM design principles for variable speed
• Optimization design
• Single-phase IM design
• Three-phase IM generators
• Single-phase IM generators
• Linear induction motors
• Testing of three-phase IMs
• Single-phase IM testing

Fully revised and amply updated to add the new knowledge of the last decade, this third edition includes special sections on

• Multiphase IM models for transients
• Doubly fed IMs models for transients
• Cage-rotor synchronized reluctance motors
• Cage-rotor PM synchronous motor
• Transient operation of self-excited induction generator
• Brushless doubly fed induction motor/generators
• Doubly fed induction generators with D.C. output
• Linear induction motor control with end effect
• Recent trends in IM testing with power electronics
• Cage-PM rotor line-start IM testing
• Linear induction motor (LIM) testing

This up-to-date book discusses in detail the transients, control principles, and design and testing of various IMs for line-start and variable-speed applications in various topologies, with numerous case studies. It will be of direct assistance to academia and industry in conceiving, designing, fabricating, and testing IMs (for the future) of various industries, from home appliances, through robotics, e-transport, and renewable energy conversion.

1 Induction Machine Transients

1.1 Introduction

Induction machines (IMs) undergo transients when voltage, current, and/or speed undergo changes. Turning on or off the power grid leads to transients in induction motors.

Reconnecting an IM after a short-lived power fault (zero current) is yet another transient. Bus switching for high-power IMs feeding urgent loads also qualifies as large deviation transients.

Sudden short circuits, at the terminals of large induction motors, lead to very large peak transient currents and torques. On the other hand, more and more induction motors are used in variable speed drives with fast electromagnetic and mechanical transients.

So, modelling transients is required for power-grid-fed (constant voltage and frequency) and pulse width modulation (PWM) converter-fed IM drives control.

Modelling the transients of IMs may be carried out through circuit models or through coupled field/circuit models (through finite element modelling or FEM). We will deal first with phase-coordinate abc model with inductance matrix exhibiting terms dependent on rotor position.

Subsequently, the space-phasor (d–q) model is derived. Both single- and double-rotor circuit models are dealt with. Saturation is included also in the space-phasor (d–q) model. The abc–d-q model is then derived and applied, as it is adequate for nonsymmetrical voltage supplies and for PWM converter-fed IMs.
