Characteristics and Application of Electric Machines
This course will help you to:
- Recognize the type of motors from their structure
- Understand the way each type of motor works
- Realize the performance of various motors based on their characteristics
- Select the appropriate motor for an application
- Gain knowledge about how motors can be controlled or matched to a load
Electric machines are part of our daily life, at home and at work. They can be as small as the motors in a toothbrush and the fan for a microprocessor inside a laptop, or very large, say thousands of horsepower. The large one can be found in industry, for running pumps, compressors and the like. These motors are not built similar and do not work based on the same principle, though all are machines that convert electrical power to mechanical power, in the form of (mostly) rotational and (to a much lesser degree) translational motion.
For those engineers who are dealing with application of motors and motor driven devices it is necessary to have a good understanding of the variety and how these machines work, how to select them, how to do the required calculation for each application, and how to take care of them.
This course covers all the DC and AC machines (generator and motor), their working principle, their characteristics, selection criteria and the way they can be controlled. An introduction to 3-phase electric systems is added, since many industrial motors use 3-phase electricity.
- Brief review of DC and AC (single-phase and 3-phase) electricity
- Lorentz force and Faraday’s law, fundamentals to motor and generator action, EMF and BEMF
- Principle structure of DC machines, various categories and their characteristics
- Classification of AC machines, main categories, rotating magnetic field in 3-phase systems,
- Speed, frequency and number of poles relationships, synchronous speed
- Synchronous motor, principle of operation, and characteristics
- Induction machines, principle of operation and categories
- Squirrel-cage machine (the most common industrial motor), characteristic curve, NEMA classification
- Wound Rotor Induction Machine (WRIM), advantages and drawbacks, speed control of AC machines
- Single-phase AC machines and their categories, special single-phase machines, universal motor
