Hallo all,

How to select in VESC Tool the COM port of PC for USB connection to VESC6?

Menu connection: Port "COM1" is the only port shown. Clicking button "refresh serial port list" results in nothing new, only COM1.

The last working connection was shown as COM6, but after successful running motor wizzard the tool lost connection when I tried to select the control input. (Should be ADC, wired potentiometer.)

Hi,

I understand that when moving from 4.12 to 6, the current sensing method was changed from 2 shunt 'bottom side' to 3 shunt 'in phase' .

Current sensors for in phase applications - specially for high voltage application are pretty expensive, and the only credible option for me seems to be the ACS758 or variants that other members seem to be using.

Questions:

- Is there any benefit of 3 shunt 'in phase' sensing over 3 shunt 'bottom side' current sensing for FOC ?

Link above is a google drive link to download the custom built VESC controller. (Note that I have designed using Altium designer, you may need to use altium designer or circuit maker to able to view it)

Hi

                                                     I' am having doubt's regarding which rotor position estimation method should be used for a 1 Kw surface mount PMSM.  Is it possible to use signal injection method for finding the rotor position?

Thanks in advance,

Hi, Gianni from Italy, I'm a glider pilot and I help friend in my flying club to transform into electric PPG - HANG GLIDER - GLIDER,  unsatisfied for the poor results using commercial BLDC motor finally using my experience I design and build my own brushless motor.The motor was designed also for liquid cooling for heavy use. My idea, and the results are proving me right, is to have only one model of motor that can be used on different projects and with uneven performance and power demands.

Hello and greetings to all forum members, especially Benjamin Vedder for his great work!

We are a company in Germany that develops and produces the word fastest diving scooter SEABOB (www.seabob.com).

Actually we are planning a motor controller based on VESC technology.

For this we are looking for an experienced software developer with advanced knowledge of

• VESC

• FOC

• ChibiOS

• STM32F4xx

• CAN

Hi guys,

First of all apologies for jumping into this forum and directly asking questions ;)

I work in the field of drones. For me ESCs are sort of black boxes and I found it time to dive a bit deeper into ESCs. Searching for more programmable ESCs I found this amazing open source ESC.

Hello All-

Hi All

I am attempting to build a friction drive E-bike, but am new to Brushless motor control and am at a loss as to why my set-up isn't working.

I'm using a Flipsky FSESC6.6 with 6354 190KV Motor, and the generic Hall throttle from Bangood.

I've had some intermittent success getting the motor set up through the FOC wizard. However I am unsure if FOC is relevant to my application?

Hi guys and girls, 

I hope there is room for a very noobish question. I am playing around with a Vesc and a Turnigy bldc, 22 poles, 24 stators, 320 Kv.
