We have this Huge Process Blower employed on our Plant, which is running with reduced voltage starter, 300 KW, 440v motor is driving its compressor. the thing is we waste 40% of its generation, utilize only 60%. we are thinking to replace it by VFD and using closed loop control only generate enough Air we required for the process.
Please share your experience of utilizing VFD on such a huge motors
