    Selecting and Sizing Single Phase Motor Start Capacitor

    Ok, took a closer look at the nameplate this evening. The name plate does say "Capcaitor Motor". However, there are not any capacitors mouted to the case, that are typically seen on these motors. It is a Dayton Brand, the nameplate doesn't list any capactitor sizes though. Just your typical...

    Selecting and Sizing Single Phase Motor Start Capacitor

    Yes, this was not a cap start motor. It will start and run without a load on it. I have installed the motor on a small table saw. With the load of the blade (only a 8" blade), the starting amps are to high. My intentions were to put a capactitor on this motor so it would start easily...

    Selecting and Sizing Single Phase Motor Start Capacitor

    This motor does not have a capacitor on it now. I am wanting to put one to it. That is why I am inquring as to how to properly size the capacitance of it.

    Selecting and Sizing Single Phase Motor Start Capacitor

    I am wanting to implenent a start capacitor into an existing 120V 1hp motor. Can someone provide me with the proper forumlas, or reference material for selecting and sizing the correct start capacitor? Thanks,

    Transistor Selection, Replacing PN2222A

    The current I am trying to pass is typically 114ma, and there is not an output capacitor. Below is a schematic of my cirucuit pasted in a from a simulator, perhaps this might help. I have not noticed excessive heat from the transitor. The 1k pot is used to "tweak" the output voltage to...

    Transistor Selection, Replacing PN2222A

    I have a design that is currently using a PN2222A Transistor, it is on the output side of a LM723 Voltage regulator, to increase the current capability of my voltage regulator. The circuit is designed to output 12VDC, the collector is connected to a 24VDC source. The problem that I am having...

    SAE dash size reference

    Does anyone know where there is a chart or some form of reference for SAE dash size as to what they represent. I have a port that is 1 5/16-12 SAE, and I have another that is 1 1/16-12 SAE, that I would like to know the dash equivalent of them are. TIA.

    Need Help. Delta Flow Divider 50/50

    Ok, the answer I found was that I could tee the line from my valve and go into both inlets or I could plug one, and use only one inlet port.
