I can offer 115 volt single phase input 230 volt three phase output to 1.5 hp (this is without derating the drive)
I can offer 230 volt single phase input 230 volt three phase output to 5 hp (this is without derating the drive)
I can derate a drive to operate with a 230 volt three phase input but cannot derate a 115 volt single phase input drive. There is no way to develop 230 volt in a drive using 115 volt above 1.5 hp. I must have at least 230 single phase input to run a drive the normally operates at 230 volt three phase (6 hp minimum) and is rated for a 3 hp 230 volt three phase motor. I would double the hp rating of this drive to handle single phase in and three phase out.
With that said I would need to have a transformer to take the 115 volt single phase to 230 volt single phase. I would then set up the drive to take 230 volt single phase in and rated to handle the amperage for a 3hp motor.
SM250 AC Tech 5 hp variable frequency drive $316.80
DS0034 Teco 3 hp 56 frame 230/460 three phase motor ODP $172.46
I am awaiting information on the transformer.
Would you be able to quote me a replacement motor that is 3 phase, and a VFD (variable frequency drive)? I would like to keep the cost down, but would it be possible to get a motor with 80% turn down?
Is there any reason not to run a 3 phase VFD with 120 single phase input and 230v three phase output?
