An introduction to electric motors. Mechanical energy What is an electric motor An electric motor is a device converting electrical energy into mechanical energy (usually a torque). This conversion is usually obtained through the generation of a magnetic field by means of a current flowing into one or more coils. 2. Purpose: This qualification is primarily vocational, or industry oriented, characterised by the knowledge emphasis, general principles in computer aided design and simulations and application of Electrical Engineering technology. The diploma in Power/Telecommunication /Process and Control Engineering qualifies the technician for employment.
This book has been written for a course of study that will introduce the reader to a broad range of motor types and control systems. It provides an overview of electric motor operation, selection, installation, control and maintenance. Types and Applications Austin Hughes. out of 5 stars 9. Kindle Edition. $ Ugly's Electric Motors Reviews: A three phase induction motor is basically a constant speed motor so it’s somewhat difficult to control its speed. The speed control of induction motor is done at the cost of decrease in efficiency and low electrical power discussing the methods to control the speed of three phase induction motor one should know the basic formulas of speed and torque of three phase induction.
induction motors in the range of to 90 kW, with 2- or 4-poles, rated for V-line, 50 Hz,S1, Duty Class, in standard design. Motors sold in Europe had an efficiency marking designated as EFF1 for their best efficiency, and EFF2 for standard efficiency. There is lower EFF3 level classes of. Depending on the class and application of the motor, the locked rotor torque can take on values of , , or The value of is the appropriate value for a pump motor. Figure 2: Menu of Essential Motor Data DEFINING THE ELECTRICAL MODEL The program uses the motor data in the motor menu to generate the impedances of the motor.

The content of this book is divided into three basic parts: 1) control-oriented description of induction motors, 2) control methods, and systems, 3) control means. An induction motor is presented as an electromechanical power converter, and basic relations between the electrical, magnetic and mechanical quantities in the motor will be explained.
The book presents a practical computer simulation model of the induction motor that could be used for studying various induction motor drive operations.
The control strategies explored include expert-system-based acceleration control, hybrid-fuzzy/PI two-stage control, neural-network-based direct self control, and genetic algorithm based Cited by: Book Abstract: Induction motors are the most important workhorses in industry.
They are mostly used as constant-speed drives when fed from a voltage source of fixed frequency. Advent of advanced power electronic converters and powerful digital signal processors, however, has made possible the development of high performance, adjustable speed AC motor drives.
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.

SPEED CONTROL TECHNIQUES OF INDUCTION MOTOR DRIVES INTRODUCTION Variable speed induction motor drives have succeeded in replacing dc drives in variable speed applications with the improvement in capabilities and the reduction in the cost of power electronic devices.
In AC induction motors, only the stator current produces. The induction motor especially three phase induction motors are widely used AC motor to produce mechanical power in industrial applications. Almost 80% of the motor is a three-phase induction motor among all motors used in industries.
Therefore, the induction motor is the most important motor among all other types of motor. Induction motors are widely used in the industries for motion control system applications. Not only in industries, but even in most of the home appliances, the induction motors are used.
The induction motors are simple and of rugged design, low maintenance, low cost and most suitable means for such applications.

5 INDUCTION MOTORS – ROTATING FIELD, SLIP AND TORQUE Introduction Outline of approach Like its predecessors, the third edition of this book is intended primarily for non-specialist users and students of electric motors and drives.
Abstract: This paper describes the field oriented control of a high speed induction motor (HSIM) with a two-level voltage source converter (2L-VSC) and an LC-filter for a V low voltage high speed drive.
The filter design procedure to reduce the torque ripple as well as the low frequency models of LC-filter and a combination of HSIM and LC-filter in rotor flux oriented frame are presented.

The National Electrical Manufacturers Association (NEMA) has specified the motors according to the various Class, which are discussed below in detail. Comparative study of P, PI and PID controller for speed control of VSI-fed induction motor 1K Smriti Rao, efficiency encouraged the use of VSI-fed induction motors in many types of industrial drive application.
Most multi-purpose A P controller system is a type of linear feedback control system. The P controller system is more complex. Construction of Three Phase Induction Motor. Like any electric motor, a 3-phase induction motor has a stator and a stator carries a 3-phase winding (called stator winding) while the rotor carries a short-circuited winding (called rotor winding).
Only the stator winding is fed from the 3-phase supply. result, AC motors are progressively replacing DC machines in variable-speed applications.
