Leopard Motor.....Schulze 32-200WK

[gerardobrandao]

Hello

Received yesterday mine LB5692/2Y.




Exterior appearance is very good,bearings are good quality.The stator laminations are 0,2mm.
Rotor seems well balanced, and the output cables from the motor are heavy gauge cooper.
Of course,the details like wire insulation quality or magnets quality can´t be defined by only "looking".


The problem is mine SCHULZE 32 200 WK is driving me nuts...I´m about to give him a shoot...
It drives correctly the NEU1527 1.5D i have, heats a lot the scorpion HK4035 800KV, and now it doesn´t drive the leopard motor.,about 3/4 throttle up the motor stars "stuttering"..i believe this is the term....No matter what timing i put,it doens´t stop the stuttering....

Here follows 2 videos, one with the schultze the other with the mgm compro 16024 race boat....

.....Please come back mine old YGE200

Hopping from inputs from your part

The Schulze is not set correctly for some of your motors. If it runs the Neu D motor but not the Scorpion outrunner, the timing is set too low. The Neu needs just 0-4 degrees; the Scorpion needs 10-15 degrees advance or it will overheat.

I am not familiar with the Leopard motors, but if the wind is a typical "Y" then it may need a different timing advance than those you have tried. But the switching frequency may be the issue, what kHz does Leopard recommend?

Also make sure you connections are solid. Cant wait to hear more about this motor.

Hello Jay


I´m still waiting for an input from leopard hobby concerning switching frequency and timing settings....

But like you know, the new XL generation has automatic timing(configurable by software) and auto switching frequency....This can´t be changed..


Just like i have been saying...i guess that he older 40 160 WK was way better then this, concerning driving different motors...

As soon as i have any input,i will post it in here..

Hey Gerardo,

Where did you buy the 5692 from? There are some of us very curious about that motor. There are multiple sources for the smaller Leopard motors but not the 56xx series. Did you buy direct?

John

[Brushless55]

yes, let us know where you picked that motor up and for how much

[RaceMechaniX]

Gerado I can't view the photobucket video on my phone, but my suggestion is to reset all the esc settings back to the default. If this has similar results try manually increasing the timing from 5 degrees in 5 degree steps. I also think a 2Y wind needs between 10-20 degrees.

Let us know if there is any change. I don't think the timing is an issue. Do you know how poles the motor has? Does the motor have a lot of cogging torque when it's turned by hand?
Or does it spin with low resistance? This gives some insight into whether the motor has a twisted stator stack which decreases the back EMF signal.

It could be my monitor but that does not look like a 5692/2Y Red series but thats a Gold series and there no info on Leopard site about this motor and i was told the Red 5692 series is still in testing at Leopard and would be sold not earlier then July. Are you sure you got the motor you ordered.

Hello

The colors is only to fulfill different vendors, but the characteristics are the same.
Desn´t matter if it´s red, green or gold.

You´re like me.....MEchanical engineer, traveling from here to there...and checking emails trough the blackberry..... :D

The motor has 4 pole, sintered magnets!IMO they are correctly positionated in the rotor since it works with mine MGM compro.

Motor has a lot of COG,much...much more then the NEU!Of course that this doesn´t mena anything....Lehners don´t cog at all hand are extremely powerfull and efficient.

Best Regards...And trying to keep help me

[focused]

I just compared the others motors and they all have the same specs so you are right , mmm wonder if my Schulze 24/150 WK would like them maybe better saving en buy lehners 2250/10 for a 8s setup instead.

Yup!

Out traveling to a vendor today in North Carolina.
I'll keep thinking about the problem.

Have you tried using different dip switch settings ? Car or plane mode may do something different.

[gerardobrandao]

Schulze

I have tried every DIP possible configurations...even governor mode in the helicopter option!

Motor desyncs past 1/2 trohttle..

Schulze answered me this:


Me:


Hello


Has attachement follows a print screen of the setup, since i don´t know another way of showing you the setup configuration.
I send you also a .LAD file from the akkusoft showing you the speed controller working for 30 seconds.
You can see the voltage ripple when the speed controller pass the 1/2 throttle range.
It doesn´t work with any timing i put,from 5º to 28º in 1º step increase!


Waiting for input


Regards



Schultze:



Hello,

at no load conditions you can use a soft timing even on a Plettenberg motor which likes hard timing under load.
So timing is not an issue at no load.

How many stator tooth has your 4 pole Motor?

We have tested the future-xl series with Lehner, Plettenberg, Kontronik and Neu delta wind and Y-Wind motors.

These motors are from 2-poles up to 20-poles.

Best regards

Gerado ,
When I can get to my laptop, I will take a look at the data.

Youre running and external cap bank right?If not add some caps and see how it runs. rubycon zl series caps 63v 470uf or 330uf. Also what is the rpm limit on the motor?

[gerardobrandao]

Cap Bank

I´m not running an external CAP bank,altough i don´t think, IMO, that this might be the issue!

It runs well the NEU 1527 1.5D wind, and in the lehner 2250/5....

The problem is with the scorpion HK4035/800 and the LB5692 2Y.....

I tought that timing could be the problem,but the answer from schulze is that timing is important hen motor is loaded,and not when is running unloaded.....
