Electrical Issues again!

[Badmofreaker]

If you advanced the timing to 15 on a D wind, you likely fried the motor. Sorry. ?

I hope not,doesn't smell burnt

Do you have a receipt for your motor purchase? It should give you the winding info. If it’s a Y wind, the 15 degrees timing should have been fine.

I will look later

The TP4070 2250 is a 2Y winding chaps.

Iirc D windings are ok to advance a little but a Y not?

Edit- Its the other way round..

 

[SrC]

D winds don't respond to Timing advance at all. The winds just heat up.
@jondilly1974 is dead on correct.
Need to confirm your if your TP motor has its windings Delta wrapped or Y wrapped. This will better paint a picture of your issue.

 

[Ari33]

See.

 

[Badmofreaker]

I will look later

You hit the throttle once or twice and then brakes come on,its definitely going into fail safe

 

[jondilly1974]

The TP4070 is also rated up to 50k RPMs and his logs show 68k. I would be taking that motor apart and taking a good look.

 

[SrC]

Need to vet this D vs Y info. So we are all on the same page. If OP has a Y then maybe Timing is not an issue.
But timing in general is usually avoided across both winds. Or at least done conservatively with one or the other.
Im seeing conflicting info on D vs Y on in searches.

I agree. The log doesn't lie. 68K rpm. Wow. Over reved????? whether Timing was a factor or not. Perhaps this Y motor did accept timing advance and over reved it.

I was sure I'd read previously that D can be advanced.. but when I rechecked a few moments ago, I found that to be wrong. :/

I believe I got my info from Raz

I have seen this video before. excellent for us all.

The controller wouldn't be an issue would it

 

[Ari33]

Imo its more likely to be the receiver.. but I guess the Tx is also possible.

Just tried the receiver, no difference, try a motor next

I want to add that timing is considered only using a sensored setup. These are AC motors and efficient timing control requires feedback from a sensored circuit with a motors Hall sensors.
Anyone else care to comment? Not to move away from the OP's issue.

Holding the other motor in hand ,I can't get it to stop,so I probably wasted the tp, but I don't have a load on it

Scratch that, I feel the motor kicking back,so either the esc or controller

 

[SrC]

To isolate the radio from the equation, do you have a servo tester to operate the Speed control and observe if motor still wont stop?
Could be the motor. Open it up??? Test the phase circuits with a VOM. Look at the arm and windings.

No,I do not

 

[SrC]

No,I do not

Another Radio/Rx.?? another ESC??
