motor:42jsf630as-1000, 8 poles 

vesc:release_5_03

When measuring the res and ind, I fould that the value changes, about the res result, can I say less than 3A is too small to lock when measuring the res, for when larger than 3A, the res result is almost the same.

But about the ind, I really have no idea why it changes in different duty, and it even shifts in same duty.

I used a RCL to test the res and ind between phase to phase, the res should be 0.55 omh and the ind should be 295 uH. Neither matches the result.

Hi everybody ! 

I just shorted a phase wire to a Hall sensor wire while throttle applied on a FSESC 75100. All the FETs are good but the FSESC won't turn on.

Do you guys think it may be fixable? And what could be the electrical components to test and change and resolder?

I have a spare 75100 for parts. 

Thanks all of you for the support!

I'm trying to set up to use this motor which apparently has no Index line. I have an FSESC V4.12. and V4.20.

My goal is to get smooth movement at low speed. From barely a crawl to 4 mph, maybe 6 mph tops. So for this wheel that works out to about 300 RPM. I need to avoid cogging.

The robot is also pretty heavy. Full loaded maybe 200 lbs.

no one responds to a simple suggestion request, so better delete everything anyway! 

Hi all first question....

controlling a blcd motor total via the can interface ? is this possible if so how ???

any links would be great thanks

I've been working on a design that will allow me to use an AS5047P encoder on a hover board motor.  I can't attach the magnet directly onto hub motor because it is a single shaft so I've created a geared assembly.  Here is a link to an image of the design I've created.  I've printed it and installed it with no issues.  The encoder and magnet just attach to the spaces on the middle of the small gear and back of the arm.  The big gear has 64 teeth, the small gear has 25 teeth.

I'm building an electric scooter. I managed to make a nice interface using qml that works fine inside vesc tool. Now i want to wire on an external touch screen for that UI, but have no idea how to do that. What interface do i need (i2c / uart / other)?  Do i need an additional microcontroler like an arduino?  Any advice would be greatly apprciated!

Hi,

I noted that in all the available schematics --> https://vesc-project.com/node/311 the termination resistor of the CAN bus is 220 Ohms, however it should be 120 Ohms.

Am I missing something or has it been overlooked?

Thank you

Ok, so bear with me as this is conceptually in its infancy.

Autonomous vehicles are a dime a dozen with tons of projects (donkey car, etc) that all work to certain extents.  So assuming one of those off the shelf navigation systems 'works', I've been trying to think of ways to implement it to a skateboard.  Because why not!
