Overview
This course is held online over 2 days on the following schedule (All times in Eastern Time Zone):
10 am to 6 pm Eastern (Will include the usual breaks)
After participating in this course, you will be able to:
- Gain knowledge about many types of motors that exist
- Recognize a motor type from its structure
- Understand the way each type of motor works
- Learn the characteristics of each motor type and realize its performance in operation
- Select the appropriate motor for an application
- Learn about how motors can be controlled or matched to a load
Description
Electric machines are part of our daily life. They can be as small as the motor in a toothbrush and the fan for a microprocessor inside a laptop or as large as thousands of horsepower for running pumps, compressors and the like. These motors do not have a similar construction and do not work based on the same principle, though all are machines that convert electrical power to mechanical power.
For those engineers dealing with motor-driven devices, it is necessary to understand: the variety of motors, how they work, and how to select them. This course covers all DC and AC machines (generator and motor) but emphasizes motors. Their working principle, characteristics, selection criteria and the way to control. An introduction to 3-phase electricity is added since many industrial engines are 3-phase.
Who Should Attend
Engineers and Managers working in the Design of Equipment or Applications Using Motors and Generators • Technicians and Maintenance Personnel • Operators in Manufacturing and Processing Industries, Insurance Company Personnel Dealing with Various Industries • Technical Personnel in Power Generation Plants
- Special single-phase machines
- Variable Frequency Drives (VFD)
- Other types of motors
Time: 10:00 AM - 6:00 PM Eastern Time
