No, go in OI interface and see if you have correct pole pair set for your motor equivalent


Hi,

I was able to fix all issue above. Seems like the motor is happily running on above condition. I might install it soon on my electric motorcycle if time permits,

I was also wondering which a ...

Hi,

I was temporarily to fix the over current issue after playing with manual LD and lq then pinswap. The problem went back again after I fix the magnet and encoder. Not sure what happen, but the inverter is reading the correct encoder position. I was wondering if dead time has to do with it ...

No, go in OI interface and see if you have correct pole pair set for your motor equivalent


Hi ,

I was able to make the motor ( small 20v bldc motor from mini one hand chainsaw) run for around a second with some revolution and my low power supply ( 330w laptop charger) suddenlly, I did put ...

No, go in OI interface and see if you have correct pole pair set for your motor equivalent


Hi,

I checked the OI and doubled check if i put the correcr motor pole pairs , and its a correct motor. I also tried changing it but still i am getting 0-360 even if i just physically turn the motor 180 ...

Ah your chip could be set to different pole setting. Leaf motor is 8-pole, 3-phase, 48-slot machine. Could be that you have a 4 pole count set in chip and ...
Or you have FOC set incorrectly?

Read the datasheet if there is a possibility to set pole count on resolver chip.


Hi,

Thanks for the ...

so are you reading A and B encoder or Sin Cos return encoder. there is a difference in pulse return. do you have a scope?
Check the.schematic for.resolver i showed you...there is resistor.that should be removed i think...


I have cheap mini handheld scope. But I am not sure how to. Use it,.

I ...

you are pioneering here as the SDU board is meant to drive the SDU motor with direct sine control.
You might be able to run a sin/cos chip on the AB inputs.
AB encoders are not suitable for PMSM control.


It seems like a and b channels is readding it but I am not getting full 0-360 rotor ...

I would suggest you go and research the shit out of posts on this blog as this is something no one has tried yet....
1. FOC should load but you need to know which settings/inputs you need to select in the web interface so it doesnt trip I dont know about running PMSM with tesla board, i know i did ...

For to days update,

I was able to run the inverter without tripping unlike before.,

What I have done was to correct current sensor power supply, now it's reading 2.5v on output pin using multi meter then set inverter pinswap to : 1 and 2.

The motor doesn't spin but rather vibrate after changing ...

Yes. I have little background on electronics specifically on board level. So it's seems ...

Hello Guys,

I recently got my self a Tesla SDU inverter and OI drop in board and it having some problem, here the list of question and problem that I have encountered.

1.) Is the OI drop in board for Tesla SDU can be program to drive PMSM with FoC
2.) I have tried using various kind of sensors ...

It seems like Johannes is wrong about the mlx90380,
I checked the voltage output it was 0.5-2.8v on multi meter after having doubt, I finally check it on datasheet. And I found that the output range is not really 0-3.3v..

This style sensor is pretty sensitive to alignment and magnet strength which translates to the functioning air gap. Are you using the correct (diametrical?) magnet?
Do you have a warning light for too much / little magnet force?
Will the rotor spill some magnetic forces out where you'll have the ...

I was now able to get a decent signal.

It came out that the board that I have is not compatible or defective.

What i have done is I tried wiring my mlx90380 smd manually as I have spare parts as redundancy and it was now giving a decent signal even if I just hand holding the magnet and chip ...

No idea....
I guess i am implying you test it and take one for the team...:).
Probably you should use some 60Vdc and one small PMSM motor for testing...


Hi,

I just got my mlx30980 encoder.

But the problem is only 1 signal output is work.
And i am still using the 3.3v
Yet to try the 5v ...

SDU is SINE firmware. If you want to run PM motors you need FOC definitely.

For your aplication you will use sine - cosine encoder and you do not need R1 excitation output your sensor board already signals two analog signals. You will need to intercept that using existing inputs that were marked ...

1. Not gonna work. OI interface isnt setup to work from UVW inputs. I used Lebowski with that....

2. There should be a third input on the OI interface. But maybe not because SDU drop in board was prepared with Tesla ACIM motor in mind. Like you said you want to investigate your options with ...

Tesla SDU is ACIM motor and that only needs somewhat 60 pulses per turn which will only tell inverter how fast motor is turning. This is enough for OI sine firmware.

If you want to have rotor position as well you need two signals 90deg at each other - A,B signal. This will also give you direction ...

What kind of sensor you are using again?
The way you describe it you are using polarised magnet on the end of your axle with sensor chip logging angular change rate. But the most important is what kind of output you are receiving on the other end. There are several outputs usually available:
- UVW ...

Correct me if I'm wrong, but wasn't the Panigale one of the first motorcycles where the engine is part of the frame? So if you remove the engine, the bike is in two parts? 😅


Hi,

Yes it is thru, and thats the main advantage why I choose the ducati panigale v4,

1.) i can easily fit any battery ...

I'm not sure if this post is genuine. A Panigale is a very attractive and sought-after motorcycle that stands out thanks to its low weight and exceptional, powerful engine. It is completely unsuitable for conversion.


Hi,

as far as i know stock ducati panigale v4s can only do 200-210hp,

but ...

Interesting! Post some pics of the project


Hi,

at the moment i dont have any good pictures but this is the sneak pic I can share.

Most of the parts are from ducati panigale v4s , some are upgraded to fit my needs.

-Modifier Brembo Rcs Corsa corta 17 and 16,
-Stylema Caliper set,
-Ohlins ...

Photos please

For encoder I propose you use RLS encoder circuit with polarized magnet. You would have to make a mount for magnet on the rotor and mount for PCB on the casing side.

Hello everyone,

This is my journey on converter ducati Panigale V4s to electric version and i need help.

Most of the parts is already onhand such as the following,

- Motor (5 poles IPMSM )
- Inverter ( Tesla SDU powerstage with Open inverter board )

But for make everything fail proof i ...
