    I think your writing style is causing confusion as you mix statements about customer support with your desired configuration in the same sentence.

    But I did parse out that you wish to have an RPC...

    I would look at what would it take to make a manual mill out of it. After assessing wear, look at if the drives can be removed and handles installed. It looks like handles may be installable with...

    Regarding using a hose other than hydraulic hose, you need to state what criteria you are looking for that would require a different hose type. I would use a hydraulic hose. They are readily...

    Well since your question was open ended about for what..... I'll be light on details as it was done on a classified project. It was used to keep electronics cool. But we did not waste air. We used...

    I agree with motion guru. If your motor has internal overtemp protection then all you need is a contactor as opposed to a starter. If it was operated by a pressure switch from the factory it should...

    Audio discussions have always irritated the hell out of me. So just sticking to the tube/transistor topic (and there are so many topics (monster cable, gold plated connectors, analog vs digital) I...
  7. I haven't replied to the thread because I am not...

    I haven't replied to the thread because I am not knowledgeable regarding the PP. But I do have a multi idler RPC consisting of three similar 7.5 hp motors and that is where the thread has seemed to...

    I suspect that switch just optimizes balancing for different size loads. Is there not a max rating on that unit?

    Per their website: When selecting a Rotary converter, the largest motor to be...

    I have used a cheap DRO as well and received a display unit that became intermittent. I believe the failure to be an internal trace failure on the printed circuit board. I was sent an additonal...

    I'll admit total ignorance to how a motor works but obviously there needs to be a magnetic force between the stator and the rotor. And this usually requires some iron and some windings to create a...

    Hopefully you only need static balance as you will never be able to dynamically balance that structure with out adding a protruding structure opposite of the handle. That also means that it can not...

    I think you have it reversed. A transformer should be wound to compensate for losses in the transformer. When reversed, the compensation would be reversed and now you would have the losses in the...

    I am not saying your solar system is not sized appropriately but I think you are overly optimistic about its output level. My home solar system is 20 panels rated at 320 watts each for a total of...

    Rons

    I have seen a lot of simple and clever designs for removing the belt from the pony motor. I would prefer to leave the belt engaged (whats the harm?) than have to hand hold some awkward pony...

    Lots of good information coming to you.

    And JST is correct regarding my suggestion of 480V from a single phase inverter (and that is what I was thinking) is a no go. But he got me doing just a...

    I think that you have become focused on the RPC instead of the best topology for the entire project. By spoon feeding us information you have been getting a lot of answers that have been evolving...

    For the input power, you must multiply the three phase current by approximately 5/3
    to account for the same power from a single phase circuit. I don't think you did that.

    As you asked, yes you can stop a 3 phase motor with just opening 2 leads. I have not seen it done and I would consider it bad practice as it leaves power connected where it is not expected. I would...

    I am still waiting to hear what the service panel is for running this as questioned by JST. At full load the single phase current will be running north of 200 amps. In a 200 amp panel, most bus...

    Do you have an electrical diagram for the bandsaw? If not, how do you know what parts are needed?

    If this switch is the correct part then I would think it is only one piece of a multi part...

    In the US the styrofoam is about as common as dirt. And you are correct, it is polystyrene.

    Per google search: Styrofoam is a trademarked brand of closed-cell extruded polystyrene foam (XPS),...

    How I would interpret this is the motor tag is that the 2.4 kw converted to hp is 2400/745=3.2 hp. Due to motor inefficiencies the power and phase angle the current is higher and thus the...
  23. I am confused by the information on the motor...

    I am confused by the information on the motor tag. 5.6 amps three phase at 480 V is about 4.5 kW. I would double check those numbers. Perhaps the current is for 240 V operation. That would make a...

    Keith

    Transformers can be used in reverse. Most transformers are manufactured for use as a step down transformer such as 480 to 240. The step down transformer may be reverse connected and used...

    Auction terms say as "where is as is". They should not move anything.
