Third Party Hardware

I've been working on an open source low-cost VESC 6 based ESC that uses TO-220 FETs, low-side sensing, and a few other hardware differences. I've noticed that the older motor detection process in the older FW (FW3.62) yields more consistent motor parameters than say the newest firmware (FW4.1). The newer FW can have a very difference values (especially inductance) and cause non-ideal motor operation in comparison. I was wondering if anyone knows all that factors that could affect the measurement in this case.

I am having issues driving big motors with VESC firmware and IGBT (they explode when driven above 90% duty)

is that spike normal for trapezoidal modulation?

In the oszi capture the motor is running at low speed and no load, yes i am respecting the deadtime specs for this IGBT 2,4us

Signals explanation:

Yellow: Phase-Ground Voltage

Blue: high side Gate signal

Pink: low side Gate signal

Green: 0.5mA shunt detecting shortcircuits

Hi all,

i want to update my self made PCB (first version here https://www.vesc-project.com/node/801) and hope someone can have a look at the schematic:

- It is still a modified VESC 6 and the PCB will be again in a round shape. It is not for commercial use.

- i did some modifications: add filtering, add undervoltage switch off for DRV, change NRF to UART for BLE Module, fix some bugs

- is there something missing ? Maybe a TVS diode to protect the DRV against voltages >60V ?

Hi

I am looking to control a bosch active line motor with the FSESC 4.20 controller. 

I plan on running the motor at about 20A. I have seen the conversion done with a 6-series, but since the FSESC 4.20 is so much cheaper and it seems that I am trying to use it within spec, I am inclined to go down that route. 

Is there anything that is obviously wrong with my plan?

I've just purchased a FSESC ESC V4.12 VESC. I'm noticing some odd behavior. After auto-calibrating everything on a battery I decided to hook it up to a bench power supply. The VESC seems to think that around 50% duty cycle that consumed is around -0.20 amps? Not sure what's going on, but for reference the bench power supply is showing around 1.6a. Note that I auto-detected the settings on battery power, not on the bench power supply. Screenshot below.

Thoughts?

Dimensions：55mm*35mm

Voltage：3-7S

Current：20A

Hello,

can somebody explain to me what steps one needs to take to get vesc firmware on cutstom hardware?

I am thinking of creating my own custom esc (just for my projects) and I am looking for easy to use firmware since I have no idea about software (I am ok with C Programming but I have not yet programmed microcontroller)  and how to flash them.

As far as I understand it should be possible to adjust vesc to work on a custom board based on a stm32f0 which I wanted to use for my esc. Is that right?

Dear all:

We are developing our own motor controller. It is not based on Vesc firmware/software and use a PSOC microcontroller from Cypress. However we are followers of Vesc project because the great ideas are always discussed here.

We would like to characterize our the controller in a systematically way, not just but using specific motors of specific power. Do you know if there is a commercial Test Bench for motor controllers? any link? company? Any comment will be welcome.

Regards,

Joaquin.
