We had a great turnout for webinar #107. We covered lots of information and registrants asked excellent questions. Highlights:
  • Comparing required and available power when driving a conveyor motor with a VFD at various belt speeds
  • Understanding heat dissipation in air-cooled and oil-cooled motors
A recording of the complete 3/3/21 webinar has been added to our Webinar Library.


We also posted three videos and three blogs on this important topic, as explained below.
VFDs and Motors Part 1 of 3:
Understanding rates is essential when driving motors with VFDs.
  • Materials Handling Rate (TPH)
  • Belt Speed (FPM)
  • Motor Rotor Speed (RPM)
  • Power Supply Frequency (Hz)
VFDs and Motors Part 2 of 3:
Understanding powers is essential when driving conveyor motors with VFDs.
  • Required Mechanical Power (HP)
  • Installed Motor Power (HP)
  • Available Electric Motor Power (HP)
  • Power Supply (460v/3ph/60Hz)

VFDs and Motors Part 3 of 3:
This video shows how to set VFD supply frequencies correctly to avoid
  • Mechanically Overstressing Motors
  • Compromising Cooling Ability of Drives.
