Random questions, but has anyone used one of those generic rickshaw motors availble with VESC? I having been working to get this motor working well with a Flipsky 75200 and am having a hard time with violent startup/cogging. Using the "select motor direction" features is EXTREMELY smooth. I can't get it working the same way in FOC.
I'm trying to use the Shutdown Mode function in the App Settings to turn off the Vesc after certain time, however it seems like it never gets activated. Is there any setting that could prevent this function working?
Also, I could not test, but the kickstart wakeup functin should be automatically active after the sleep?
I'm using a simple FOC controller coupled to an ADC input, nothing else. Firmware V6.02 on a Vesc 6 MK VI HP.
Thanks!
Greetings People
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:
