    Ok , thanks!

    PSC motor design

    Thank You ! You have been helpful . I found the website link immediately above very interesting . In your opinion does the schematic for the capacitor start/run motor seem to be the same configuration as these so-called PSC motors ?

    Because that is the voltage that breaches the dielectric . Great analogy - I get it ! Thanks

    PSC motor design

    Wow ! I haven't made the deal on the capacitors yet ... so ... you are describing the circumstance as I thought I understood it . If this were an election with me abstaining , however , there would be no clear winner . I can't vote because the reliability of my calculation is poor . The total...

    PSC motor design

    I just made a rough calculation based on the voltage surge . I calculated the surge difference due to the change from 370 to 440 volts at 7.5 uF to be like +.5 milliamps/sec ; which , would be a negligible number to a winding . If I did it right , I guess the capacitors are interchangable in my...

    Thanks sreid ! That is what the guy wanting to sell them to me is saying , also . It somehow shreds my understanding of such things ; but , may well be the case . According to jbartos (above) , when he wrote "it depends" , it seems a question still open to conjecture . Curiously , what did you...

    PSC motor design

    I thank you for your response . I understand the split/shift phase function of the start winding and the capacitor amplification of the field . The motor is of the 370 volt PSC series and operates 208-230 volt (1/2 HP ; 2.9 amp ; 1075 rpm ; service factor 1.0 ; 60 Hertz single phase ; thermal...

    PSC motor design

    Monophase AC motor types using a run winding and a start winding comprise several types based on splitting the phase. The start windings determine the direction of rotation and the induced magnetic field is often amplified with a capacitor in series with those windings. In Capacitor Start motors...
