When coming up with or working with a VFD control panel, it is crucial to Stick to the company’s specifications and recommendations to guarantee safe and economical operation.
Contactors and relays are electromagnetic switches utilized to control the flow of electrical power to the motor. Contactors are usually used for top-power applications, whilst relays are utilized for decrease electrical power prerequisites.
One of The best ways of handling harmonics is to place a sine wave filter on either facet of your VFD. At stake facet, these are typically termed line reactors and also have reactance values any place involving one.
Open/Shut IGBT’s in Pairs To obtain our 3 phases, we need to open and close switches in pairs to direct the move of latest to kind our source and return paths, that way the connected motor will expertise Alternating latest.
In case you have any questions about VFDs or about Drives and Generate Factors in general, add them from the comments below and we can get again to you personally in fewer than 24 hrs.
