If you drive a 3600 rpm motor with a 1800 rpm motor, Will it produce 30Hz? Would the windings need to be energized momentarily with DC when up to speed before applying the load to assure they are excited?If the slip of a 1800 rpm motor makes it more like 1725, than the 30Hz generated might be closer to 25Hz?If 220v 25Hz is needed and the 3600 rpm motor is spinning at half speed, would it produce half the voltage, and possibly need to be wired for 440v to get the wanted 220v? Will the voltage generated vary with the current being drawn? I know a lot of questions. Buffalo NY will be soon loosing the 25 cycle power currently being supplied from Montrael Canada. It used to come from the Shelkof station by the Rainbow bride, but that station was demolished by a rock slide in the '60's. So there are still a few places in Buffalo that use 25 cycle. One is the grain elivators. ArcherDanielsMidland, ConAgra, and General Mills. Also some places still have 25 cycle freight elevators. I am new to this problem, and just investagating things at this point to provide some alternatives to either new motors or a VFD. I am assuming 3 phase 25 cycle, but there used to have 400V 2 phase 25 cycle. If ths is the case, my idea would not work, I assumed 3 phase motors. I don't know where you would find a scott-T trans set-up today. As to the questions, just a general would it work type of thing, that might stimulate thoughts. Thanks for any info, --Doozer
