Hi!
Are there any tricks to improve low RPM torque in FOC mode? It seems that very low speed torque is better in BLDC mode than it is in FOC. I'm using hall sensors. What parameters should I try to tweak?
I'm using my custom HW with 200A motor current so maybe there are some parameters that need scaling from their defaults?
Thanks!
Hi all
I'm using a VESC 6 for position control and I have noticed that every time I boot VESC tool up, my position readings are different from what I've been getting before. I think I've pinpointed the issue to the fact that the encoder angle offset is different from the previous reading.
So is the angle offset being different after every boot up normal, or is there something up? Do I have to go through the encoder detection procedure every time I boot VESC Tool up? Any clarification on this would be greatly appreciated.
Hi,
I am a new guy , I just get a HW4.0 based board and try to test it .
what I found is that speed is different using FOC mode and BLDC mode .
BLDC motor : 400KV, Power:25V. MAX no-load speed should be 10000rpm @25V. (400 * 25 = 10000 rpm)
In BLDC mode I got 9300rpm( it's not bad), but in FOC mode it just ony 8500 rpm,too slow ...
I think two modes(FOC,BLDC) could be different a little bit. But 9300rpm : 8500rpm ,it's too slow to use FOC mode .
Hi guys
I'm doing some tests with the VESC 6 for rotational position and I need some help. Since most of my tests involve the motor rotating to an angle that I want through the VESC, is there a way to change the speed at which the motor travels to the angle other than changing the switching frequency?
Hi, my BLDC servo motor has both internal hall sensors and an incremental encoder (see info below)
I have Chibi studio set up on Windows. I am trying to figure out how to open the vesc project. Simply importing the entire repo folder results with a ton of template projects from the STM32 examples, but not the actual vesc.
Does anyone know how to simply load the vesc project in a new install of Chibi Studio?
Hello everyone,
I have a homemade VESC 6 (with some hardware difference) and I'm having trouble programing the MCU (STM32f405).
I would like to upload a bootloader so I can then update my VESC from VESC Tool. Can I upload the boatloader of VESC 6(from Benjamin's Github) or do I need to rebuild the bootlaoder with my hardware specs ?
Can someone also remind me how to uplaod a bootlaoder to the MCU ? I found multiple tutorials online but I don't know which to follow..
Thank you very much
Jessica
Hi,
I have a vesc from the "torque" vesc from diyelectricskateboard dot com. I'm controlling the vesc over can and needed to add a custom packet, so I clone the vesc git repo, added my function, changed the following preprocessor define:
`#define HW_VERSION_410 // Also for 4.11 and 4.12`
And then did a `make`
Hello,
