having been dusting off the controller. However now it wont even spin the motor. All calibrations run without an issue. However it sometimes will not go out of drive 1 or keep flashing the led and not power the stage up. The hex is below. version:293_ 0x0133 0xFFFF 0xFFFF 0x0503 0x03C2...

Got a lebowski Chip controlling a Honda IMA inverter Gen 2 i believe. The custom PCB Spun a Lexus Rear differential motor or MGR from an RX400h Also spun a Remy motor. http://www.diyelectriccar.com/forums/showthread.php?t=163650 Then I built it into a volt inverter for more voltage...

Lebowski and Arlo1, thank you for this kind advise. I could have also realized this myself since I have been busy building a BMS with current shunt. But as I did not write the software I had no clue on wat size of ADC we are running. :roll: (weak excuse :D ) She spins real good once in mode...

Thanks Lebowski, I will give that a try. Need to figure out what changed to make it all of a sudden not work because I need a reliable solution. So to reset all values you enter "1" is that one of the many secrets this chip has? :)

So my setup with 1K R and 10nF resistor is fine. Will keep debugging my setup. If all else fails I will have a play with the Rinehart PM150DX I got laying around

I just noticed that the first schematic dictates a rough estimation for the RC filter for the current sensors, My current setup is 1k resistor and 10nf cap However im just running 4K Hz pwm so I would need to be at a 4K resistor instead of a 1K, would this make a big difference? Tomorrow I...

Got something really weird happening. 4 months a go I was super happy to finally have the controller working. 7cJJQT425fo Come back to it a month or two ago, for some reason the IC was broken. Ordered some new ones and built the setup in my garage, now it does not want to spin properly. and...

Just saw Arlo's video on accel limit, damm this is awesome for snapped couplers or shafts from smashing your car. Or during some massive air ofcourse :D Need to hurry my butt up and get a car to bolt my Lebowski Chevy Volt inverter to.

Cool Project. One thing missing is why are you building it and what is your budget? I did some cad puzzling with different frames I found on the internet, one of them is a duc monster frame. Way too narrow to use for alot of batteries. One thing to look into is having the motor sprocket inline...

Sounds good, will built a permanent setup in so I can get some real load on the controller and then I can experiment with setting up limits.

Changes?

The lebowski chip is closed firmware and only magnet motors. Here is a link to the Huebner controller, is all open source. http://www.diyelectriccar.com/forums/showthread.php/another-homebrew-ac-controller-45909.html

The idea behind taking an OEM controller is taking just the expensive bits, so the powerstage. Capacitors, Igbts, drivers and current sensors. Then you hook up your own flavor of controller, currently aware of the Lebowski variant for BLDC position sensor less or with hall and the Johannes...

7cJJQT425fo She spins good. :D What i did is top left header the pins are as follows: GND Cur A GND Cur B GND Cur C So I addded a resistor literally between direct output from sensor and ground only because it was this way on the original logic board. Reason most likely is due to needing...

Lebowski, thank you for helping out. And also all the other guys. I was about to throw the towel in before Christmas, but it was nagging me that something basic must have been missing. I did a evening of tracing the connectors on the oem logic board. Turns out the current sensors are connected...
