Free Rolling BLDC Motor on Scooter - No Regen?

Hello,

I'm using the SBL1360 to control a custom brushless hub motor scooter I'm building.

I've gotten the control and microbasic to function mostly as intended, but one thing that's stopping me from developing it further is the resistance in the wheel I feel when there is no throttle on the scooter.

I believe this is because of the regenerative braking feature because when the controller is off, there is no wheel resistance. I've looked at the Roboteq articles on regenerative braking, and am not sure of what type of circuit to use to turn it off.

Do you think this is a regen issue or perhaps a closed loop speed issue? (I've tried turning all PID values to zero and changing to open loop and it doesn't help)

Any suggestions and help is very appreciated! :)

I can email my xml file if needed!

I think my issue is due to regen based off of this article: dev.roboteq.com/dev1/index.php/forum/14-...eration?limitstart=0

I'm using a 7S battery on a ~250W 6.5" hub motor

Thank you for the response!

I would like to eliminate resistance at times in the code, especially when the command is zero.

Is there any risk to enable and disable the E-Stop repeatedly in the microbasic code?

Is there any other way besides activating the E-Stop to get the same effect?

Essentially, I want to replicate the feeling of standard scooter motor controllers - not sure why they don't have this feature?

Thanks!

Yes, I believe this is exactly what I'm looking for! I had seen the article before, but didn't realize it applied to my situation.

I will do an in depth read and try it out tomorrow. After a quick scan, I didn't see any mention of closed vs open loop mode settings. Will the micro basic script at the bottom work in closed speed mode?

Thanks!
