Third Party Hardware

I run a 4.12 ESC on a sensored 125 KV Motor (Turnigy D5035) with 10S Battery.

Whenever i go with max Speed for 50 sec. (Power usage < 1kW) it refuses service for 2  to 3 min.

After that it is again ready to run

The ESC is less than handwarm. The motor is approx 40 degree Celsius.

Payload is approx 25 kg weight on a rail-carriage.

Does anybody have a good idea how to resolve this deficiency?

Hi guys, 

I'm working on higher voltage ESC to replace my older 100V (500A) ebike controller as there is plans to change my 24s (a123 20ah Lifepo4) battery pack to 24s Li-ion battery pack. Project details so far:

I am running a MY1020 48 V 1500 W motor on a VESC, BLDC works super good but FOC is crazy rpm limited.

BLDC reaches the specified 22500 erpm easily but FOC does not go over something around 4300 erpm.

Is there anything I can do to make FOC work as nice as BLDC?

I am awaiting a A200S in the hopes that it will handle it better.

I am running the motor of a 4P14S LiFePo4 Pack.

My dual FSESC 4.20 stopped working (one side only), and can not be programed - it supplies 5v fine, but 0v on the 3.3v line - and if I plug my external programmer in, the programmer shuts down (the 3.3v problem seems to be a short - which is why the programmer "gives up", because it can't supply 3.3v into the short).

The same programmer worked fine on both sides before, and works OK on the working side.

Obviously, the USB doesn't work at all on that side either.

Hi!

I'm back with second generation of my BESC controller. I took a few different approaches this time.

Hello,

Ive a big problem with my Flipsky 4.12 50A VESC...when driving for a few minutes it suddenly starts to brake randomly for 1-2 sec then switches back to normal and repeats after a short time again and again.

This is very dangerous...I almost fell from my board because of this.

My Motor setup:

BLDC / Motor Current Max and Max Brake: 50A / absolute max current: 120A

Battery current max: 50A / Battery current max regen:  -20A

I have two brand new Flipsky 6.6 Dual Vescs.  I can connect to one via USB but not either side of the other one.  I bought a ST-Link and can connect to both of them that way.

The one that I can connect to is programmed the way I want the second one.  Is there a way to download the configuration from the one I can connect to via USB (or ST-Link) and upload that configuration to the other one via ST-Link ?

thanks,

I have 2 of the VESC's you can buy from TorqueBoards.
