EM 61 Motor Winding connection

[@garbizwal]

Its Come to my attention. The audio is not working in the left side. So with headphones you hear the audio just fine but only out of the right side. I apologize and I will try to get a new phone soon. But if you are having problems maybe turn your headphones around.

It could be 2 set of wye coils in parallel, they could be wire in a way that both centre (neutral) are link by a 4th wire (oppose to have all 6 coils wire crimp together )

[@Sourdough_Humboldt]

The 4 wires on each side could be 3 phases and one jumper wire going to the other wye connection. 6 phase wires and 2 ends of the jumper wire, 8 total

I saw somewhere a Delta motor with a fourth connection for ground but doubt if that's what's going on here.

[@alibro7512]

Any connections on the other side? If the four ends are just two sets of winding's in parallel and there are two more the same then isn't that delta?

[@garbizwal]

I don't see how. But maybe. I am still under the understanding delta needs a number of connections divisible by 3. And no there is nothing on the other side. I think it was just easier to wind it this way then they did their connections on this side. I am fighting a cold and its making me dizzy... SO its hard to focus... But I will figure it out.

@@garbizwal I probably didn't make myself clear but if you find another connection hiding somewhere you'll know. I've stripped a few alternators and the ones wired in Wye have a single bunch of wires for the centre connection. Wouldn't it be odd to have a motor wound in Wye with more than one central connection? Maybe they didn't have room for a single large connection and used a link wire to connect one of the phase ends. You'll figure it out though and when you do please post a new video as this is very interesting work you're doing.

@@alibro7512 Yeah I did a split phase Zero motor. I found the WYE connection and split it and the 2 sides of the stator and run dual controllers with it. But this seems to be different. WAY different. I think its because they didn't have a very good winding process and needed a way to connect series/parallel connections.

[@CrAzYDr1veR]

can the em 57 take the same power as this 61? Wondering if you would have a better time uncrimping a 57 instead of this one :)

[@alibro7512]

The internet says no, my understanding is the EM61 is a higher power motor.

[@garbizwal]

@@alibro7512 I haven't proven this yet but the stator is longer on the EM61

[@alibro7512]

@@garbizwal You've proven way more than anyone else I know of. On the forums I frequent they claim the EM61 is more powerful but I haven't seen any official documentation to prove this.

Not only are your EV motors silent.....so is the entire commentary.
