well guys, i did try the capacitor approach, but i was unsuccesfull. back to the drawingboard...

thank you audioguru, i was trying to use the ac motor instead of a dc motor, because the ac motor is 1/3 the size and about 1/4 the weight. which benefits my project greatly. what is a power factor correction, and how difficult is this to achieve since you mentioned that it is a can of worms?

Hopefully some of you can bring some insight on what i could do to this project i wish to work on. I am trying to power up an ac motor with an inverter, but it just does not seem to work. Here are the specs: the motor- 1hp 115vac 60 hz 11a. the inverter-12vdc to 120vac 2kwatts max 4k, mod sinewave. I definately must be missing something somewhere, the inverter powers up to about 1300 watts on its led meter, the motor tries to turn but within about 3 secs the inverter alarm goes off and shuts off. I did try manually to turn it and then flip the switcch, but i get the same result. So far i have tried 4 differ motors. (1) the one i mentioned, it is treadmill motor (2) a frigidaire dryer motor rated at 1/3 hp (3) a dayton motor rated 1/2 hp, this one only had 2 connectors for it (4) an old leeson, a 1hp motor that has a hump on it, it's capacitor, this motor actually started and was prob about 80 rpm when the inverter shut off. I was thinking about transformers, maybe if I am able to find one that has a 1 to 1 ratio, but i am not sure if this would be my answer. I also thought maybe the inverter is not producing the right hz, but i am not sure how to fix this and i do not have the equipment to check the hz. Can anyone help?

thanks for the input, i do apologize for placing this question in the projects section. my goal it to have at least 90 volts and 160 amps on the end side of the power equation. I was planning to put together enough psu together in parallel and series to achieve this end volts and amps. I know it is quite a project, but I feel I can accomplish it. My goal is to power a dc motor. The motors data is 72-120vdc 130amps cont 150 amps/hr 500amp peak. I know that once i have completed my psu it should take up an area of 3'x4'. I understand that I will have some losses somewhere, but i am not sure where and how much. I was planning on using 15 psu's, me being optomistic and little experience, i was hoping to get the 90vdc @160amps. I greatly welcome your design, ideas, help, and suggestions. As well as info on what components you guys would recommend for my build, ie capacitors rectifiers and diodes.

Hello, I am working on a project that requires dc volts. Currently my power supply generator is 30vac @ 32 amps. I would like to know if there is a way that I can transform the 30vac to 30vdc and keep the 32amp range. I would appreciate the help from anyone that can offer it. PS. I have not worked with circuits since i was in junior high school (very long time ago), I suppose that once I can refresh my memory, it should get easier.
