You can not easily generate that much; there is no easy way to morph 60 into same. Such will make a real difference in motor speed (duh!) unless it's really crude (electric drill/hair drier motor w/ brushes) or exotic (chopper controlled with feedback regulation, etc..) You might be able to rent/find a 5-10 KW gas generator and slow it down to make 50; it may or may not still make 220, but that's a little easier to handle, find a Variac. You want a bigger one because its efficiency will fall off. There ARE test sets that generate 50HZ from 60 (actually, 60->DC->50) but offhand I do not know where you'd find one. Maybe a major exporter of toys (LockNortGrumMart or such) would have one they use. Or hit all the equipment rental outfits. -- A host is a host from coast to [email protected] & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
