Extend Your Knowledge in VFDs and Drive Systems

Have you ever asked yourself any of the following questions?

  • Shall I specify/purchase a DFE or AFE type of rectifier?
  • What VFD technology suits my application the best?
  • How to specify/calculate/measure the efficiency and losses of a drive system?
  • What cooling method shall I prefer?
  • How can I avoid harmonic problems and penalties for low power quality?
  • What input power factor can I expect?
  • How does LCI compare with a VSI?
  • When does regenerative braking pay off?
  • How do the harmonics cancel in a multi-winding transformer?
  • What to do in case of grid resonance?
  • Do I need a cell bypass for my VFD?
  • How to solve mechanical vibration issues?
  • Can my VFD handle severe grid disturbances?
  • Shall I select single drives or a multi-drive?
  • What to consider when calculating the life cycle cost?
  • How to read the winding connection / vector group of a multi-winding transformer?
