WebAug 7, 2024 · Yes. VFDs have the same nominal output voltage as input voltage. If you have a 415V supply, you buy a 415V input - 415V output VFD. You connect the VFD for 414V operation. It makes no difference whether the motor was originally connected star or delta, it must be connected for 415V operation. When you disconnect and reconnect the … WebA VFD (or Variable Frequency Drive) achieves this by converting the AC power to DC. The VFD then sends out a DC pulse that acts as an AC sine wave to control intensity. Operators can select the desired output frequency to control the speed of the motor. There are two main types of VFDs. Voltage/Hertz VFDs are the most common and cost-effective.
