  • About the Edition

    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.

    Induction motor starting can be analyzed using electrical, mechanical, and thermal models which interact as diagrammed in Figure 1. In the electrical model, the voltage, V, and the slip, S, determine the rotor current. The summation of all torques acting on the motor shaft comprises the mechanical Size: KB. An essential requirement for this practice is the modeling and analysis of machine electrical losses under variable frequency operation. In this paper an improved steady state model of single phase induction motors is derived to investigate major motor characteristics like torque–speed, input power, output power, by:

The induction machine d-q or dynamic equivalent circuit is shown in Fig.

One of the most popular induction motor models derived from this equivalent circuit is Krause’s model detailed in [13]. According to his model, the modeling equations in flux linkage form are as follows: B.

Modeling and Analysis with Induction Generators the first edition of this book, published in The reasoning was that although so many books have been written on induction machines, drives, and motors in general, none existed at that time that would cover.

It has been more than a century since the principle of the operation of induction motors was discovered. The first industrial motors of this type were constructed at the end of the Nineteenth Century and soon gained the favor of users who appreciated their raggedness, simplicity and relatively low manufacturing cost compared to DC commutator s: 1.

There are many reasons for selecting the induction of them are as follows: 1. Induction motor is a singly excited motor where as synchronous motor is a doubly excited onous motor need an additional dc source for excitation of. Induction motors constitute a theoretically interesting and practically important class of nonlinear systems.

They are described by a fifth order nonlinear differential equation with two inputs and only three state variables available for mea-surement. The control task is further complicated by the fact. Induction Motor is an AC electric motor, having a stator and a rotor just like other motors, but the working principle is a little different which would be discussed further.

There are two types of Induction Motors, one is named as Single Phase Induction Motor, while the second one is named as 3 Phase Induction Motor.

For the steady state analysis of the symmetric three-phase induction machine, one can define the simplified space phasor of the stator flux, which is collinear to the total flux of the (αs) axis and has a 3 times higher modulus. In a similar way can be obtained the space phasors of the stator voltages and rotor fluxes and the system equation Cited by: 1.

often. The single-phase AC induction motor best fits this description. As the name suggests, this type of motor has only one stator winding (main winding) and operates with a single-phase power supply.

In all single-phase induction motors, the rotor is the squirrel cage. Induction motors are present in any processes and systems and for this it is important to known the types of faults which can occur during its working.

This paper presents briefly some electrical and mechanical faults in induction motors and how these faults influence the motor by: 4. energy is consumed by electric motors and over 90% of them are induction motors. The minimization of electrical energy consumption through a better design becomes a major concern.
