Attached is a snip of the stator.

You can see that the windings are not forming adjacent coils.

Hi PmgR,

Those last simulations seem to be corrupt with diagonal black lines.

Thanks for checking the CEMF flux.

Looks like the forum has a problem with handling GIFs. It appears the file gets corrupted either during upload or download. I have zipped the gif file and re-uploaded it. Then downloaded it and it says it has a CRC error when I try and unzip it. Anyway, it still appears to work and unzips correctly.


So download the zip and extract it and then please confirm it works.


Stefan, can you look into the fact that GIF files appear to become corrupted, or maybe the forum can't handle animated GIFs?

Yes, the forum corrupts it. Unzip it anyway, tell it to ignore the CRC error. Then double click the GIF. You can use PowerArchiver to unzip it. It will ignore the CRC error.


Not sure how/where else to upload it.


Btw. L192 check my first animated GIF once more again as it looks that one is no longer working either. I just downloaded it and it appears corrupted as well.

I have regenerated the animated GIFs at a slower speed and put them together with flux plots into a zip file. Let's see if this uploads properly.

Looks like that worked. Some information on the images:[/size]


Input coils are 44 windings each. Output coil is 1500 windings in my simulation (not sure what Pierre is using).



Config000_animation_delay0250.gif: this shows the flux progression when six coils are driven by a 1amp current and the coil activation is then shifted step by step over a full rotation. I have set the delay for this animation to 0.25sec, so let me know if this OK. It appears rather slow on my computer, but I might have a slow computer.


ForwardFlux.emf: this shows the flux in the output coil (6 input coils driven as mentioned before with 1amp each as above) as a function of the rotation step (36steps, 1 step = 1 coil shift)


Config000_BEMF_animation_delay0250: this shows the flux progression when the output coil is driven by 6.38mA of current (all input coils are turned off).


BEMF_Flux_OutputCoil.emf: shows the output coil flux under above drive condition of 6.38mA. The current of 6.38mA was chosen such as to exactly oppose flux caused by the 6 input coils.


BEMF_Flux_InputCoils.emf: shows the flux caused by the 6.38mA of output coil current in the various input coils (1,10,19,28.29) as a function of rotation.


The induced BEMF voltage on the input coils is proportional to -N*dflux/dt and in order to see the impact of this on the electronics we will need to know a few things:


1. Number of turns for each input coil
2. Number of turns for output coil
3. Winding configuration
4. Recovery diode configuration/schematic
5. Coil connection coil configuration/schematic
6. Dimensions of metal of stator and metal of output coil

Hi PmgR,

All good perhaps a little slow now.

you are still simulating coils in adjacent slots rather than coils with a larger pitch. Whereas I agree that we dont know his exact detail, you only have to look closely at the stator to see that the coils are pitched between 6 to 8 slots. This would cause a large increase in  inductance and induced flux.

The question of why two relays. Why?

72 relays 36 transistors ??

Maybe he is using them as a charge pump? Charge coil (relay), stop current, spike over a diode to a cap, repeat

As previously posted.

I think he is using the two relays in the same configuration as a two transistor switch (like a you get in a forward converter).

As the relay coils are isolated you only need one transistor to switch them both.

Oh Yes!  , "As the relay coils are isolated you only need one transistor to switch them both."
But what is the benefit of that? Two diodes with loss. (small)
The return wire (red) is relatively thick. Just a coincidence.

Hi Seaad,

With a single ground-referenced relay switch to drive the coil, the drawback to this approach is that the voltage stress on the switch is the sum of the bus voltage, the reflected coil voltage, and the turn-off leakage-inductance spike.
If you add a second high-side relay switch, the voltage stress reduces to the bus voltage only.

The two MOSFET switch is the only one I use when switching coils now, as the circuit is very robust however, a high side driver is required so component count goes up.

Regards

Hi L192,


I will make the frame rate 0.1sec for the next animation.


Regarding the windings, I understand what you are saying, but let's say a winding covers slots 1-10-19-28 (9 slots in between), second winding covers slows 2-11-20-29, etc. last winding 9-18-27-36, then you would only need 9 transistors as it become as 4 pole stator with only 9 sets of windings to drive. Then why is Pierre using 36 transistors?
