Unable to Detect Motor Sensors | 100/250 VESC | HPM5000B 72v 5kw GM Motor

I have been trying to get a 100/250 VESC to use a HPM5000B 72v 5kw Golden Motor Motor but when I go through the motor wizard I get stuck at "Failed to Detect Motor Sensors." When I decided which sensor wire to plug into which hall I went with this: The sensor wire that matches the color of the motor wire that I plugged into motor wire A goes into sensor 1, motor wire B goes into sensor 2, etc. (I would attach a picture of the motor sensor connector but I can't figure out how to attach a picture.)

What I Know

The motor has worked previously with an ESC

The VESC is turning on

The receiver wizard was able to work without issue. 

Flashing the firmware didn't fix it

The sensor wire is getting 5v

The 3v setting didn't work

The motor has 5 pole pairs

 

What I Have Questions About

Why is the biggest outrunner only 2000g (The motor weighs 11kg)

Why did it automatically set itself to 14 pole pairs, I tried setting it to ten (the motor has ten) and that didn't help

Is there some way to check if one or two of the sensors are working?

 

Any help would be appreciated

The sensors on this motor work, we tested that. Big Outrunner should work for detection, but the motor runs best with tweaked parameters. Search for golden motor in this forum and you will find the tweaks.

Pole pairs need to be set manually to the number of magnetc pole pairs. This only affects the real time data like speed, range, profiles etc. It doesn't affect how well the motor runs.

 

Found the info:

The Goldenmotor can be detected with the wizard. Then you go to Motor FOC and change the Time Constant ( T ) from 1000uS to 250uS. After that you re-calcualte Ki and KP via the button Calc Apply Old.

Then write the motor config to the ESC and you should be good.

Thank you, I will try this and get back asap. (I am in high school and it is AP exams time so I'm not entirely sure when that will be.)

I connected to the software, changed the constant time from 1000uS to 250uS, and hit calc apply old to find the ki KP values. After that, I wrote the motor config to the vesc and when I then tried to go through the wizard it said "failed to detect sensors" again. I can't figure out what the issue is. The only noticeable thing is that the vesc flashes the red light six times in a row but it has done that since the beginning so I think it is doing that because it hasn't been programmed. Again, any insight would be greatly appreciated.

If your temperatursensor is connected try wizard without it. Some tempsensors need to be set up in general advanced tab correctly before doing the Wizard. I had this problem on older firmware, not sure if it is still a problem.

Do you mean physically disconnect it? The white connector that you have to use for the 100/250 vesc makes it hard to remove wires. I can try that but I am not sure how that would help.

Yes, physically disconnecting the Temp PIN on your Vesc. Its very easy to disconnect the PIN on the connector. See herehttps://www.youtube.com/watch?v=nRVhPhfdawg
