    help with IR2110 chips

    there is a ground if you look closely, but how do I full rectify it? I set the coils to 3.2ohm. and corrected that top left one If the coils are 3.2ohm and that is 15% less than the impedance, then the impedance is 3.76ohm 3.76 / 2 * 3.14152 * 128 = L = 4.68mH so now I have set the...

    oh ok that L5!! so is that wired up correctly because this image looks wrong to me surely it should be more voltage!!??!!

    what is the power coil array? I think that it's already grounded if you meant the 8 power coils/supplies could you do a mock up in spice of how to do it please, thanks or even explain or put rings around the places that need looking at! thanks I took the square root of both the 11.24 and 0.376...

    so the power sources are 10volt and the wheel turns 8times a second and there are 16 magnets 8 * 16 is 128Hz the inverter is supposed to invert the DC that come from the coils the diode and the smoothing cap, to invert that DC to an AC voltage, and that is where the 50Hz comes from - the pulses...

    help with IR2110 chips

    so measured the resistance again today the 230volt side is 3ohm and the 40volt side of the transformer is 0.2ohm there was four wires black yellow orange and red red to black = 0.4ohm so I paralleled then with the yellow and orange to reduce the resistance whilst keeping the same turn ratio...

    stuck two cores in the first set of two coils, they're made of ferrite welding rods with the flux crumbled off, trolley works like a charm!

    soo what are your thoughts on this? please help!!!

    help with IR2110 chips

    so I measured the resistance's which the internet says is 15% lower than impedance Z and L = Z /2pi*f f is 50hz and doesnt mH mean milli H I can't even find L5 as far as I can tell there're L1 L2 L3

    help with IR2110 chips

    so I've calculated the inductance by this equation L = Z/2pi*f f is 50Hz Z is impedance and the resistance is roughly 15% less than impedance so my coils have resistance of 2.5ohm and the inductance for it is 9.36mH I'm using a step up transformer so the primary resistance is 0.1ohm and the...

    how do I add inductance to the power coils?

    help with IR2110 chips

    so my meter does do impedance and I found the formula L = Z/2pi * f take more readings tomorrow! where do you put the inductance in for the coils?? and I took it the the resistance is around 15% less than the impedance using those figures, the coils are 2.5ohm - inductance 9.36mH, the primary...

    help with IR2110 chips

    ok so the power coils have a resistance of 2.5ohm each! the primary winding 230VAC side is 3.0ohm and the secondary 40VAC side resistance 0.1ohm

    help with IR2110 chips

    ok I'll get the resistance's and go from there!! thanks there anyway to calculate the inductance?? without knowing the number of turns? I have a meter that measures capacitance not sure if it does inductance too!!

    help with IR2110 chips

    so if I measure the actual resistance of a coil and the resistance of the transformer windings, that would help? I can do that tonight or for definite tomorrow!

    when I, alt + left click the one in the red circle it says "V(N002,N005)*I(V7)" at the top of the sim window. Also I've included the asc file of where I'm at

    is that realistic?

    help with IR2110 chips

    why is it negative?? and so does that mean 95watt with the rest of the coils summed up? that is good! going to try and get a PWL file from my scope so I can simulate with an actual waveform from an actual coil!!, thanks
