Industrial Variable Frequency Drive (VFD) Installation and Application Issues (Part 2 of 2)
June 16 @ 12:00 pm - 1:00 pm CDT
This webinar will present a detailed overview of common industrial VFD installation and application issues as well as additional considerations for advanced issues of harmonics, filtering, and energy efficiency. This presentation is part 2 of 2. The full agenda for this presentation is:
- Motor Speed vs. Maximum Load / Cooling
- Use of Motor RTDs
- Overspeed with Fans / Pumps
- Increase in Torque and Power
- Minimum Speed with Pumps
- SCCR for Drives
- HRG vs. Solid Ground
- Shaft Grounding Brushes / Bearing Currents
- Load Reactors on the Output
- Wiring on Input / Output
Rick Hoadley is a Life Senior Member of IEEE and has been involved with AC and DC drive development and applications for his whole career. He received a Bachelors Degree in Electrical Engineering from Cornell University, Ithaca, NY, in 1973, followed by a Masters Degree in 1974.
Rick started at Borg-Warner Power Electronics in Ithaca, NY. In 1987 he moved to Rockwell Automation in Mequon, WI, holding engineering management positions with their Low Voltage Drives group. In 2009 Rick joined the Medium Voltage Drives group at ABB in New Berlin, WI, as a Principle Consulting Applications Engineer, creating the test facility needed for their MV drives, obtaining UL listing for the drives, and working with customers’ applications.
His expertise has been on power quality and harmonics issues associated with AC drives, along with system simulations and unique drive applications. Rick has authored and presented several papers and tutorials on DC drives, AC drives, AC drive applications and AC drive harmonics at Powercon, AISE, PCIM, IEEE-IAS, PCIC, PPIC, APEC, ICEM, CWIEME, along with in-house seminars and publications for Rockwell Automation and ABB. He is the holder of five patents and three Innovation Awards all associated with AC drives.
During the school year Rick teaches courses at the Milwaukee School of Engineering on circuit analysis, electromechanical power conversion including transformers, motors and generators, and on power quality.
In his free time Rick created and maintains an award winning web site called “Cool Magnet Man” (www.coolmagnetman.com) that provides interesting experiments and information about magnets and electromagnets for elementary through college age students. He is often contacted to give presentations to middle school students about the Wonders of Magnets.
