Hi folks,

I have components of my EV conversion up for grabs :cry: :

150kW Rinehard 100-720V Inverter
3.6 NLG513 Brusa Charger (200-520V) (including all wiring/connectors)
BorgWarner eGear
Unknown motor (see Picture)
Unknown DC/DC Convertor (see Picture)
Benchtop Power Supply (30V/20A ...

I found this motor connected to a BorgWarner gearbox. It has no nameplate or any markings. Can anyone help me identify the motor?
Kind regards,
Jan

Hi Guys,

I stumble upon some used IGBTs - InfineonFZ600R65KF2. They are used but still in perfect working condition. The units have been swapped for preventative measures. I have about 2000 units . The price is €100 each. Anyone interested?

Hi Guys,

This is great work. How can I get my hands on a couple of boards for testing?

Hi Johannes,

Have you used this power module yet? Do I understand it correctly as this would be a plug and play with V2 or V3 inverter kits?

Well done! This is great work!

If there are still some left I would like to test them in my Morris Minor. I would need 14 slave modules and 2 isolator modules.

Hi guys,

I swapped A and B and now it works! Whoop Whoop! Thx for the help!

Hi Jack,

Thank you for the reply. My speed encoder is set to AB and is reading the speed just fine. Any suggestions on how I could play around with these or other parameters to get more speed / higher freq to the motor?

Hi Guys,

I got my motor to turn but it is turning very slowly. fstat (my guess it this is the freq send to the stator) seems to stay below 5 almost as if limited even if I turn my pot to max.

I looked at BMS input (connected to gnd), Error input (Pin 13) is 5V and UVLO input (Pin 14 ...

HI Guys,

I changed the current sensors to one that I borrowed from a friend and now the motor is running at 150V.

Do you think there is something wrong with my sensor boards?

Hi guys,


Can you post a plot of the il1 and il2 at 1000 samples and 1000 display limit? Is there any indication that the current is actually very high? Are the current sensors calibrated?


1. I calibrated the sensors a while ago with motor running and the sensors connected to that motor ...

Update:

I lowered the DC bus voltage to 50V from 150V and setting fslipspnt 10 and ampnom 20 started to turn my motor. Finally :lol:

When I increase ampnom to above 40 the inverter stop. I am trying to search for the cause but cannot get the it. My guess is some current limit? The ocurlim is set ...

Hi guys,

Thanks for the response.

I connected the temp sense and it reads around 30°C.

I still get these errors when I run the inverter with fslipspnt 10 and ampnom 100. It is as the inverter work for a split of a second and then switch off. The error codes:
[501]: DERATE - TMPHSMAX
[52830 ...

Hi guys,

When I try to start the inverter in manual mode I get the MPHSMAX - DERATE error after running

set fweak 10

start 2

set fslipspnt 10

set ampnom 100


I think the issue is the precharge circuit. I looked at the relay output of pin 20. What should the output voltage be? I have changed ...

Hi Johannes,

The above link are broken. Could you please assist?

Hi Johannes,

Thank you! That did the job!

Hi Guys,

I am so exited, just received my kit. :geek:

I seem to run into an error with the voltage sense board. In the Errata the instructions for the fix is to connect the pin 2 of JP1 to the closest VCC. But originally on the board (and schematic) pin 2 of JP1 is connected to ground. Am I ...
