HomeVariable speed drive
In my opinion the most important consideration is the application itself. Variable frequency drives are current limited devices and choosing the right VFD requires that the VFD be able to deliver the needed current for all circumstances.
As starting torque is important for its selection we must give details of torque required based on drive (may be gear, load). Also important is location of variable speed drive. If it is away from motor then we have to provide chokes for impedance. This is generally told by supplier. We also need to inform the bypass system for VFD if our application is important from application point of view.
