Facts Worth Knowing About Frequency Converters gives a simple introduction to the work and build-up of a frequency converter and the AC motors connected to it.
The basic elements are described in four main sections:
- AC Motors
- Frequency converters
- Frequency converters and motors
- Protection and safety when using frequency converters
CHAPTER 0: Introduction
- Advantages of infinitely variable speed regulation
- Control or regulation?
CHAPTER 1: 3-Phase AC Motors
- Asynchronous motors
- Stator
- Magnetic field
- Rotor
- Slip, torque and speed
- Efficiency and losses
- Magnetic field
- Equivalent circuit diagram
- Speed change
- Changing the number of poles
- Slip control
- Frequency regulation
- Motor data
- Types of load
- Synchronous motors
- Reluctance motors

Control or regulation?
Many people use the terms control and regulation interchangeably. However, they do have precise definitions – largely as a result of developments in the field of automation.
The terms “control” and “regulation” depend on the type of plant. With speed “control” a signal which is expected to produce the required speed is sent to the motor. With speed “regulation” a feedback signal is given from the process.
If the speed does not correspond to the requirements, the signal to the motor is regulated automatically until the motor speed is as it should be.

Very useful information for Application Engineers
..thanks for sharing this tachnical information, very useful for my sons!
You’re welcome Luis.
The download link doesn’t work it lead us to a new page .. not even the search option show any search reasult .. i’m using chrome on android… plz tel me the solution..
The articles presented is very usefull and improves the the knowledge level appreciably which is needed for any practicing Engineer.
Great for application Engineers.
great
so good!!
