Redid Motor Config : Integrator limit came to 127.17 and rounded down to 125. That OK?
Also hall sensor detection failed. and wont spin in hybrid mode. changed back to sensor-less and unplugged h s wires.
PPM settings
Is the Max Watt setting accurate for Dual Motors? (1200)
Oh man! That was awesome! Took my first ride to the truck to go to work. The skys cleared , beaming sunshine down on Texas for a maiden run in the 70°s (f).
I went with the low wattage setting, and soft limit the erpm to 35000 for now. (about 15mph / 25kph). Seriously, I don’t know how you guys are looking at 25mph+ boards. That’s seriously fast!
It was so sweet cruising up to the truck, right to the door, packing it up, and off to work. My dream come true!
Still looking for hall sensor help, but I’m on the road now and can’t adjust things fast/ take quick pictures, but I I’ll do what i can.
@Ackmaniac - moved to my build thread for clarity and not to muck up your thread –
No. I do not give full power. I only weigh 135 and that would put me on my butt. I am slowly getting more confidence to squeeze harder, but the added power is appreciated on hills. I definitely over-engineered my board. But with your firmware, I have tamed it until I can take full advantage.
The gearing is 13/36. I have 97mm wheels. With my weight, I figured there was enough torque but ability for speed. But it seems to stop at 21MPH no matter the settings. Maybe that’s the max for 8s?
Well according to the ESK8 calc, TOP speed is 23.07 18.46 weighted. So I guess I’m pretty close.
The reason for your topspeed is the 8S Battery. But you can modify your battery’s easily to a 12S with 6Ah. So you would get 50% more speed. But you should set the max ERPM in the motor settings to 60000 if you have 190kv motors or higher. You will not reach those ERPM’s on the street but on the bench. And you should switch off the “Limit ERPM with negative torque” to be safe. Because if you reach those speeds on the street you do not want to start braking. The VESC should simply don’t give any power anymore.
I have finally figured out the sensor wires from the motors, and thanks to @Ackmaniac’s new update to the BLDC tool, I have set up FOC mode with sensors with the no-miss tool tips. Things are coming together for this hobby!!
Welly its a really cheap deck to begin with. I expected it at some point. The weak point was at the holes for the truck mounts. There are small cracks along the length of the deck around both the front and back mounting points.
It happened at very slow speed though, just a walk off when I heard the motor mounts start to scrape. I thought i had tun something over and it was dragging. There are a few potholes / pavement cracks that I have to hit on my way to work. I’m sure this was the cause of the stress that cracked it.
I got really into the weatherseal. That was a PITA. Forgot I was taking pictures of this re-do.
I put a coat of paste wax on the exposed bottom and the wheel wells. Hoping this will repel whatever water might get splashed.
I was sooo worried the 97 ABECs would bite. Didn’t have a problem. I left the risers on because of the motor mount clearance. NO BITES on the test run! Back in business!!
