VESC Original Hardware

I googled a lot about encoder connection to VESC. 

I found that VESC 6 does not need modifications when connecting AS5047P encoder via software SPI bus to HALL port. And there is another way of connecting encoder to hardware spi port, but I have to to recompile firmware in this case.

How it works on schematic side that now is possible use HALL port for sensors and SPI without hardware modifications?

Hi,

I just bought a 75/300 board and I thought it could control 3 motors... Only understood my mistake when I saw one motor sensor connector....

Is it possible to connect two 118kv motors from Trampa on the same 75/300 ? (I assume there is no way then to read the hall sensors from second motor ?)

Also, does anybody knows of any cheap option for 5kw motor that could be driven by the board ? (I'm using it to electrify an old mower)

Thanks,

Hello FOCers :D 

I have built a couple of VESCs (4.12), but this latest one I built is exhibiting rather strange behavior.A

As soon as I connect the vesc via vesctool, the dutycycle green bar in the lower part of the screen shows 110% duty cycle, and it always stays there (ocassionally it jumps around, but most of the time it is solid 110-20%). 

I am guessing it is either a hardware failure (MOSFET? Shunts? DRV?) or a short somewhere. 



Does anyone have a solution to this problem? Thanks so much!

Hello All,

I have 75/300 with NRF Dongle (https://www.trampaboards.com/vesc-connect-nrf-wireless-dongle-p-26767.html)

I connected dongle with serial COMM cable and Bluetooth is working.

Also I have Vesc WAND remote. And pairing is not working. I switch on WAND but seconds just going from 10 to 0.

Could you point the right way to pair WAND?

I have a few faulty vesc 6 which failed from a bad motor hall sensor (I think, both died on the bench running motor detection).  I successfully repaired one replacing the stm and reflashing.  The second one also now connects but I get fault_code_high_offset_current_sensor_1 and red flashing led at powerup.  I reflashed on USB but still have the same error so I also replaced the 8301 but with the same problem still.

Any guidance on what to check next?

Hello,

I'm using the VESC75/300 in an application doing braking (regen) for an extended period of time.

I'm using a low-inductance motor with BLDC at 20-40KHz and we have good, albeit electrically noisy, performance.

Hi,

I would like to use the 75/300 in a boat application. We now use a Plettenberg NOVA15 with the Plettenberg MST 60-290 controller and I think the motor can run more efficient with the VESC controller. As well as more option for controlling the motor (like speed control). Is the 3d file for the aluminium casing available so we can convert it to liquid cooling? I think this would be better to attach another aluminium block to the standard housing.

And the second question: is the aluminium housing connected to ground or is it electrically floating?

Hello guys,

Hello guys,

is it true the VESC 4.12 will lose its saved configuration parameters once you unplug it? I also read (offline) that this can be prevented by using the Vedder SparkProtection switch as it upholds a small voltage after it is turned off (I tested this with a multimeter on a Sparkprotection 1.3, but the voltage in off state was just about 0.02 V). Is my information correct?

Thank you very much.

Hi to all the vesc project community ! I’m fresh to this and i’m At the final stage with a building.

Finally I’ve assembled my Esk8 and now I’m programming with Vesc tool.

But I think there is a problem with motor or maybe the VESC.

During the Motor detection it spin regularly but after it in the detection “Success!" Dialog box Under the Sensor voice it is Sensorless but the motor is sensored and connected.
