running a vfd on single phase
Im trying to get my vfd to run on single phase. the drive is rated for 380vac/460vac The company told me I could use single phase if I derate the drive by 50%, which is fine because I only need 2 hp from a 5 hp drive. how do I get 308vac or 460vac from my 120vac outlet. Is there a transformer I coul...

Re: miniature golf windmill
just had a thought on the safety issues.<p>maybe you could use some sort of shear pin like the ones on outboard motors that shear off when you hit the bottom(done it a million times) keeps you from beating up the prop or shaft too much. a small wooden peg might work. as long as it weaker then the hu...

Re: help determining AC motor
hey thats a kewl idea hehehe! I have a system designed now using stepper motors and a motion control card, card is in the mail now and is expected here this weekend. for now im going to set up the system using the steppers and some linear actuators. I have a friend that works for intelligent motion ...

Re: help determining AC motor
Thanks for all the help. I spoke with the man who built this system on the phone last year. he did tell me that the motors were 3 hp ac motors but he would not give me specifics. he is using a motion control card and 5 hp magnetek gpd515 drives. This system is actually a 3 phase system designed to r...

help determining AC motor
I am designing a 3 dof motion platform similar
to the one on this link. As I am not a physics major I need some help determining motor torque
speed hp etc.. any help would be great.<p>thanks<p>steve>simulator<p>[ March 28, 2005: Message edited by: treeman ]</p>
