Northwest Regional Industrial Training: Adjustable Speed Drives and Energy Efficiency

This  course addresses the choices available and relevant issues regarding the use of adjustable speed drives (ASD) with electric motors and demonstrates the energy cost savings and other benefits made possible by this technology.  In  this course, we explore how adjustable speed drives work and ways to assess the savings.  Variable frequency drives (VFD)  are  the most common speed control method and is the major focus of the course content, which will cover the benefits of pulse width modulation technology and well as identifying and mitigating harmful electromagnetic interference that can cause motor failure.  Additional information on evaluating and specifying VFDs will be provided.
