Has anyone tried running a copeland semi hermetic compressor at 87Hz on a inverter drive. I know the bitzer semi can do this and the have there own varispeed comprssors with attached inverter rated at 87Hz. According to the motor name plate ther should be no problem as they are rated at both 220-240 delta and 380-420 star. So this tells me that it possible from the motor side. The problem maybe the the mechanicals are not up to running at 2500RPM which is substacially above the standard 1440 RPM. I can find much on the net about this on refrigeration compressors apart from on Bitzers. Any expierience with this or feed back would be appreiciated.
Cheers
