So I built my first electric longboard about 2 weeks ago and it was amazing. The acceleration and braking torque were really impressive and it was actually really fun considering I never drove a longboard before. That was until about 5 days ago, while riding at about 20-25km/h, the board suddenly braked for no reason and threw me off the board. Fortunately I got just some minor bruises, but that sudden braking kinda stopped me from riding for a few days. Now 2 days ago I decided to test the board while it was upside down(to see if the issue is with the remote or with the VESC) and after about 1 minute of testing one VESC stopped working and any attempt to accelerate would just give the purple blinking light. It turns out the DRV8302 is fried so I’m planning to replace it, but I’m still trying to find out what caused the sudden braking and consequently the death of one VESC. Could it be that the motor shorted? Maybe it’s an issue with the VESC?
The parts used in my longboard are the following:
2x Turnigy SK3 5045 450kV
3x 6S 3000mah lipo batteries in parallel
The wheels are 83mm and the gearing is 14:36
The VESC is controlled via PPM from an NXP FRDM board(similar to arduino) that is connected to my mobile phone via bluetooth.
