Variable Frequency Drives
Introduction :
This training course highlights the relevance of Variable Frequency Drives (VFDs), also known as adjustable speed drives in the electrical installation. A VFD allows motor-based systems to adjust the speed at which the motor runs. That speed is based on how much power the mechanical systems need to meet the demand of the building. The demand of the system is also referred to as the “load” of the system. By varying the speed, the motor is able to meet the needs of the load without using more energy than necessary.
Course Objectives :
At the end of this course, the participants will be able to :
- Understand the factors controlling speed of an induction motor
- Explain the construction and operation principles of VFD
- Determine the benefits of the VFD
- Understand the VFD technologies
- Explain the importance VFD maintenance
