General discussion

Hello,

I am using a VESC 75/300 to control an QS120 motor to power an electric motorbike.

https://www.qsmotor.com/product/2000w-mid-drive-motor/

The rotor has integrated magnets in V-formation which makes the motor an IPM. I am controlling the vesc via CAN. The electric throttle is robust against electro magnetic interference. An STM32F103 reads in the signal, filters and maps the signal to write them on the can-bus. The motor is current controlled.

Hi,
I see there is PAS quadrature sensor support in the VESC firmware, but I cannot find any information to which pins it should be connected.
Does anyone know? I still need to use H1,2,3 for motor hall sensors.

Thanks,
Kaspars

I purchased a Floatwheel kit and can't get any response out of them.  It has the BalancePro V6.6+ and VESC tool can't read the IMU or the foot pad sensor (ADC1, ADC2).  I have watched a few videos and tried to set it up multiple times.  Is it a bad VESC?  If it is bad can it be replaced with the VESC 6 MKV?  Thanks in advance for the help.

Hi everyone, I got several problems with this 200 A ESCfrom flipsky: https://flipsky.net/collections/electronic-products/products/high-current-fsesc-200a-60v-base-on-vesc6. I am not new to the VESC Tool, I have been programming and using other VESCS for years, mostly without problems.

Hello,

I'm using a reference model vesc 4.12, and I'm trying to upgrade an old kids electric scooter. The throttle it comes with has 2 wires coming out of it, and is just on/off. Is it possible to use this?

Good night

I'm interested on apply this on a Interior Permanent Magnet Motor. There re any firmware option for that? Or other method to adjust?

Thanks in advance.

Hi, 

I have a Mahle motor. On the data plate it is described as a 3 phase AC motor. 48vDC 14kw. I've looked for the part number but can't find any information on it. 

The phases are marked as W V U with an additional 2 core wire which I assume is some kind of sensor. 

Does anyone have any idea what this motor is and would I be able to run it efficiently with any of the VESC products.?

TIA. 

Has anyone integrated a display with VESC using I2C? is there a reference code which I could use to build my project. I am planning on bypassing Audrino. Just connect the SCL, SDA, VCC and GND from the VESC and hook it up to the display and make it work.
Thank you!

Hi everyone,

We are using VESC in our project and we are experiencing problems with BEMF/BLDC mode on high current operation. It looks like it has some wrong commutations. 

When we add next power, our design goes to fault and stops, so I think it is a start of failures. 

Do you have some ideas? Maybe we need to change the Zero Cross detection algorithm to fix it?

Below are the pictures with current, and currents with BEMF(when everything is ok). Date is measured @ 130 kHz so there are some missing points.
