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

Motor RPM

Concerning motor RPM, i still don´t have values, but ther are 2 limitating factors....One in the motor, ball bearings, wich are from NMB brand the same Lehner uses.....And the other one is the speed controller, wich has max RPM for 2 pole motor of 240000 RPM,being the limit for 4 pole 120000 6pole 80000RPM and 8 pole 60000RPM


Very Best Regards

Yeah, I doubt its the rev limiter particularily if it works on a Neu just fine.

I would skip the extra caps at this time, they caused problems for me in till they were installed on the board.


Gerado, can you confirm what set-up worked. It was a Neu 1527 1.5D with solid connections, 10S? or 8S?

Can you send me the log file of the run to look at by zip file. Something is off, but I cannot see the parameters on the left to know which line is which.

As a side note, check the cap leads to make sure all are in tact and none are vaporized.

I have a couple other Neu motors I can run on mine, but I expect it will probably work fine.

The following was posted on another site by the distributor of Scorpion motors in the US.

"In some cases, if you have a very high Kv motor, the timing needs to be advanced to give the FET's enough time to turn on so that the magnetic field will be fully built up by the time the magnet lines up over the stator pole. If the timing is not high enough, the motor can lose sync with the ESC, and start to mis-fire.

It is best to start with the Low timing and see how that works, then try the Mid timing. If the Low works, but the motor misses a little bit on Mid timing, then go back to Low timing. If it runs fine on Mid timing, you can most likely leave it there. In most cases, the Scorpion Motors will kick back if you try High timing." Lucien

From your post it appears that Schulze didn't catch that this is an outrunner motor. Their examples were all inrunners. Try what the Scorpion motor expert says.

If a motor cogs then that is a software issue period. Changing the timming isn't the answer but it might help a little. Adding more caps can sometimes help but that is just a bandaid as well. The Castle controllers dont like some outrunners either so its just not Schulze. Also the plettinburg motors are 20 pole outrunners that Schulze was reffering to and so are the Hacker motors but they are still very different from Skorpian motors in design and how they are made. It seems to me that people are having better luck with the cheap Chines controllers for the other outrunner motors.

The setup that worked with the NEU 1527 1.5D was on 6S, and of course solid connections

Hello Jay...

i´m 100% with you in this.....I always saw that way the outrunners and timing!Altough i give credit to SCHULZE , but i guess maybe i gived to much!
Mine YGE200 worked flawlessly with the scorpion motor, unfortunately i burned the esc because water went to the driver of the FETS, and you know the rest of the story
The schulze drive the scorpion, but in comparision with heat issues to YGE200, it´s orange from apples....Same boat same setup same prop,and about 25 to 30ºC difference between temperatures after 2min.
The YGE 200 had no problem pushing mine 9.9lb pund rigger 10S with the scorpion 4035/800 with an octura 1655 prop....schulze simply cuts off...after and after....about 30 seconds....


Hello Mark....100% with you...IMO it´s firmware(software) issues.....
What i think is strange,and makes me think about it, is why motor works good
until 1/2 throttle,and above that it stars stutering,no matter what timing i have....

Schulze replied me:

Hello,

that is strange - as we tested Plettenberg and Neu motors with 12 Stator tooth and 4 poles without any problem.
Can you check that the resistance from phase to phase of your motor is nearly the same?

If you have a power supply with constant current control, you can set the current control to 5 or 10 Amps and measure the millivolts over the motor phases.

If there is a deviation of more than 10% between the 3 possible combinations something is wrong with the windings of the motor.

YES......

Gerado,

Please forward your data file to me. I am hope and have the laptop with software available to look at it.

Also, to date I have heard of anyone having success running a Schulze with an Outrunner. But this still doesn't explain the Leopard problem as its an inrunner.
