Huge AMPS

Hello Tyler.....



You are right...with 4000watts it should pull the S235 like it was nothing, but it isn´t the case......The speed controller is cool,never passed the 55ºc.....
What is heating is the motor......

Nothing better then share the FDR file, for you to give an input...

here it goes...




Thanks for your input

Gerado,

I downloaded the latest Eagle tree software, but it will not let me access the file in till I have set-up a device.

Can you take a screen shot like previously.

Eagle tree Both sessions

Speed controller never passed 55ºc


Lowered 7 amps from switching the octura1455 to the S235 and speed controller stopped cutting of,altough i´m pulling huge amps, with a conservatice setup, that whats confuses me......

Gerado,

Can you just show one set of data on there. It looks like you have three sets overlaid which makes it hard to read.

data chart

Hello Tyler


Here it goes....only motor temp, speed controller temp and amp draw...

Looks like there is a load some where in the system. Binding flex, drive dog on strut, stuffed motor ??? It should not be pulling those amps. With those props. Although Tyler could be on to something. Just keep looking for the problem and you will find it. It is a beautiful rigger and it will be great to see it running in the 80's

Binding...strut

Hello AndyM


Thanks for your input.....Mine 99% chances are speed controller software....
I say this, because with the YGE200 that i had,setup was the same, and i never had any cutt of problem and everything was a lot cooler without water cooling, neither on the motor or speed controller......

I think that next step is to buy an YGE160 HV, but it´s more 500$ dollars.....
Can´t find any other reason.....the shaft is free runing,no problem at all....


Thanks for your input.....

motor

by the way...


you talked about the motor....

It was a lot o cog, just like it was new......doesn´t seem in any way demagnetized....Is there any other way to check it out?

Can you try a differnt motor?? I would of thought Schultz would be all over this trying to get you sorted. After all they are the best or so we are led to believe

other motor

Andym


I have already tried different motors.....With mine lenher 2250/5 it cuts of sometimes, mainly when starting...already reported this issue to schulze...
The motor it works best is with mine NEU1527 1.5D, never had any kind of problem of cutt off or anything like that.....

Gerado,

What I can see on the graph are very sharp current spikes and corresponding voltage dips. I assume you are trying to run in a circle or oval with constant full throttle or very close to it. If that is true I believe the high spikes are due to mis-commutation in the controller. The high current spikes like the ones that occur near 10s, 25s and 39s cause the LVC to cut it.

From the high current and voltage fluctuations I assume it's also a 1P set-up. Under a 100A load your voltage is drooping more than is desirable.

We know the Schulze's work best with 2-pole medium inductance motors like the Lehners. The Scorpion electrical/magnetic characteristics just aren't jiving with the feedback loop system and I believe that is what's causing the erratic running. The Schulze is trying to push the amps to get the rotor at the correct position, but it overshoots or losses track and casues the heat build up in the stator.

The controller probably cuts the 2250/5 when starting or at low throttle settings due to partial switching operating which is typically has higher current than when running at WOT. The 2250/5 is a pretty hot wind at 2300kV versus the less hot 1500kV Neu 1527 1.5D.

If you really want to run this combo, I would send both motor and 32.200 back to Schulze for diagnosis.



Otherwise a motor switch or controller switch may be best. If you are considering a new controller, the Castle Hydra Ice HV may be worth looking at when its released.

huge Amps

Hello Tyler


I agree with you.....
There is a speed controller and motor mismatch......I will buy a YGE160HV to work with this motor and the Leopard.



Regards, and thanks for your cooperation

I guess save the Schulze when you run a Lehner or Neu. A bummer that the combo does not work.
