Third Party Hardware

Hi, I recently bought a Flipsky FSESC75200 to replace a 200A Maytech MTSVESC6.0 that stopped working randomly for unknown reasons.

Ive been trying to set up this new vesc for almost 3 days, but just cant get it to run properly. Ive read through many suggestions on the forum, but nothing seems to help much.

The motor I want to run is a 135kv Revolt 160sh with a 21s LTO pack (50.4V Nominal).

The best I could get it was to run okish with 100A. Above 100A I would get over current faults at 20khz switching frequency and just a loud screech at 60khz.

Hi all,

what is a good rise time for the phase voltages ?

I know faster means lower power dissipation, but more noise. but is there a preferred value ?

On my PCB i started with 1kv/us which was too fast for my current measurement (ina240).

Now i have 100V/us, is this too slow ?

Thanks

Hello,

Is anyone aware of a tiny sized VESC which is 2S lipo capable? I would like to try out a VESC in 1/28 scale racing cars. The ideal size for a VESC for this application would be approx. 30mmx25mmx10mm.

If such a small sized VESC doesn't exist is there someone that can make one?

Any leads to this info will be much appreciated!

Cheers,

Cham

Good morning...now i explain my problem. I have a scooter with two motors. The front motor could be turn on or off with a botton. Now i would have 4 different set ups with 4 different velocites in vesc tools android app. I use a ubox mainboard 75v and 200 amps . I connect the board with bluethoot . When i choose a profile, this set up Is Only use in One motor, instead the second motor works with the standard profile. Is It possible to set the same profiles in the same time? Thanks

Hi Group!

Getting closer to getting this paddle boat running.

I have a snowboard setup with a 60v/1600w motor inside a paddle wheel connected to a 75/200 ESC via 2 x 13s 14ah batteries. 

No load I can get the motor running from the VESC tool. Sensored FOC

If I hammer down on it I get an ABS Over current. (Setting throttle response to 1s solved but seemed like a hack.)

Hey, I purchased a Summerboard E-skateboard last month and they gave me instructions for pairing my remote to my board using VESC tool app.

The instructions told me to have my bluetooth on on my phone, and then to scan for the board through the BLE Connection. 'VESC BLE UART' shows up and i'm told to press 'Connect.' 

However, when I press connect, instead of it saying at the bottom that I had connected to the VESC, it gives me this: 

I am currently in the process of building my first electric skateboard. I have attached an image of the components I am using. Last month after a few tests, I had an incident where my ESC smoked up. I have no clue why it smoked up? I used the correct settings, my batteries are compatible. I wish I knew why (it is killing me)!!! Hopefully the problem lies with the ESC, i.e. it was faulty.

Now I am also concerned that the motor could have caused the ESC to smoke, or maybe even worse, the possibility that the motor has now become damaged from the incident.

Hello guys,

I'm wondering if a bluetooth 4 remote would  work if I have a nrf51822 chip connected to a VESC (hw 6 based). 

I found this thing that looks interesting:

I found it cheap, 9$ with free shipping, says it's Bluetooth 4, and already has USB connector, on/off switch and some buttons that I can use for different actions.

Leaving this for future reference.  I reset all settings back to factory in the VESC Tool, re-ran the FOC detection but selected a smaller motor size, left everything else default.  Then set up the input after that.  Did the trick.

Soft/Firmware:  VESC Firmware 5.1  Hardware 4.10   Flipsky Mini FSESC4.20 50A SK8-ESC 

Motor: Flipsky 6354 190KV 2450W BLDC Brushless Belt Sensored Motor.   Also connected hall sensor in addition to A1 B1 C1. 

I'm sure there's a bazillion of these messages cluttering this forum, but I haven't been able to find any help in a search.  Maybe someone here can make sense of what is going on/what happened/what not to do/what to do?

Firstly, I'm aware that there are a number of modifications of the name "Flipsky" used on this forum; they don't have the best of reputation.  But I decided that I should at least start cheap, instead of potentially blowing several hundred dollars with ESC newbie mistakes.  And well...

So my hardware setup is as follows:
