Motor-Generator vs. VFD?
Motor-Generator vs. VFD?
(OP)
I have an application where my existing power control room runs about 250kVA of load at 480V, 3P3W, 60Hz. This PCR will be shipped to a 400V, 50Hz country. My initial solution was to use a motor-generator set (50Hz motor turning a 60Hz Generator) due to its simplicity, few parts, and pure sinusoidal output. However, my customer is requesting an option for a VFD. My concern was that the output may be a square wave, reliability, more complex, etc. Moreover, the loads would all be powered by this single VFD. The loads consist of motors, lighting, HVAC, resistance heating, electrical outlets.
Thoughts on VFD vs. motor generator? Any experience using VFD for multiple varying loads?
