One of my VESCs are detecting my motor as sensorless. Any idea what could be the problem?
Fed 5v to hall sensors, and am reading between 0 and 0.8v on all sensors, just fine.
I seem to have a problem with FOC settings disappearing when I shut down my VESC. Other parameters seem to be remembered. Just the FOC related ones and I do write to both motor and VESC once everything is calculated. Do I need to rediscover those each time, or am I doing something wrong
Hi there!
I'm using an Arduino to send data over the Serial port to my Vesc (using de <VescUart.h> library and using the setRPM function)
All good with that, the problem comes when i make a script which sends repeatedly the RPM values over Serial to the Arduino and then the Arduino sends it to the Vesc it self.
This works well if i delay each message from the following 1,25 seconds or more, less than that (1s for example) it starts to stop sometimes and if I put a delay like 0,5secs or less it just don't spin.
Is it possible to have VESC on startup automatically run a motor at a given RPM? Similar to having a static PPM input. I'm guessing I might have to program a script or something? Possibly have a switched input on/off somehow?
Hi all,
Does anyone know if it is possible to do position control on a geared motor (belt drive, FOC mode) with dual encoders? There are 3 hall sensors on the BLDC motor (aka the forst encoder) and a AS5147 14 bit SPI encoder on the output shaft of the belt drive (aka the second encoder). The HALL sensors are used for the commutation and the magnetic absolute encoder for the (PID) position control. In case it is relevant, I'm using the CheapFOCer v2 hardware. Would this be possible out of the box (HW and SW wise)?
I have the FLIPSKY 75100 ESC and the Flipsky 6374 Motor with sensors. VESC tool is not able to detect the hall sensors with the automated detection.
On the esc side, the voltage from positive (red) to ground (black) is 5.3V. H1,H2 and H3 is about 3.3 volts. I did have to move a pin on the sensor connector because the esc is 6 pin and the motor is 5.
Hello,
I try to drive 48N32P pancake 170mm motor with 75200 ESC in 5.3Firmware.
I don't get the FOC calibration working successfully unless I set alpha values lower that 700ERPM/s and current value greater than 20AMPS.
With alpha values under 700ERPM/s the calibration make the motor turn smoothly without sync loss and I get all green value as this below:
Hello Everyone!
I have just released the video series on the DF_ESC project.
If anyone is interested in how the whole project has been developed, I have created a YouTube playlist that goes into the details, from the specifications, schematics, pcb layout and more.
You can see the completed device here:

Hello,
I'm working on my dual electric motor boat and pretty much everything works except for one thing. How do i get values from the slave VESC?
I have an Arduino that talks UART to the master VESC and then the second is connected using the CAN-bus. I can control both motors perfectly using the following code:
Using a Trampa 75/300 in a Kuberg electric motorcycle.
Works very smoothly, however motor will not start from a complete standstill. A little push is all it takes, and than it lift off smoothly.
Using FOC sensored. It's not cogging, just needs a minimum roll to start.
How can I make it start from a standstill?
