Hi all starting this as in title, hopefully compatible hardware from larger vendors and hopefully supplies.
Chime in, give your good, bad, anything goes assesments.
I am building an electric narrow gauge train unit using 1.8kW brushless DC motors to run on a 15" gauge line to access a remote cabin in Scotland. It seems more fun than a roadway.
My initial set up uses four 12V 12AH AGM lead acid mobility scooter batteries in series - mass isn't a big problem for a train!
Could the VESC 6 MkV unit use regenerative braking into lead acid batteries (with careful setting of the maximum current) or does it only work for lithium ion? I want to check first before trying.
Hi guys,
Hi Folks,
Like many here I am working on my own VESC derivative that I am tentatively calling the TINY6. I based my hardware off of the VESC 6.4 and antonchromjak's MINI4 (and learned a lot from others, thank you everyone for open source designs!). I'm about ready to send my design off to be manufactured but before I do, I figured wouldn't hurt to see if anyone wanted to sanity check some of my design decisions.
I'm a RC fans, and try to make a small foc/bldc driver to use in my model airplane.
While the size of vesc is a little big, so i did some change:
use discrete mos driver(fd6288) and current sensor(INA181) to replace Drv830x.
use mos with small package(qfn).
remove the usb interface.
use two PCB layers so that it would be much cheaper than 4 layers.
Hi,
I'm trying to make brushless motor controller for my ebike.
I need it to have (forward reverse) (potentiometer input) (maybe brake) (hall inputs)
it's going to be mostly running hall less
Im trying to make it as cheap and simple as possible.
list of components that I have on hand:
smd ceramic capacitors: 50v 1nf 10nf 100nf 1uf 10uf 100uf 100v 48uf
disc ceramic capacitors 50v 106 104
smd resistors: 10 100 1k 10k 100k (2512 shunts) 0.004 0.001
tht resistor kit with values :
I'm evaluating the Mboards BLDC ESC V6 and FlipSky FSESC6.6 for use as controllers in a machine where a motor controls a wheel that must maintain an accurate RPM between about 1000-6000RPM. When the motor parameters are detected properly, the Mboards VESC can repeatedly maintain the commanded RPM anywhere in that range. The FlipSky VESC is always off by a scaling factor dependent on the RPM. I tried tweaking every parameter allowable and cannot get the FlipSky VESC to be spot on accurate.
Sometimes with higher voltages cross-conduction occurs due to fast rise in drain source voltage driving gate voltage above threshold.
I came with this solution. When 15V driver voltage charges gate to 10V C1 charges to 5V. When driver voltage goes to 0V it should put negative voltage on gate and making it harder to cross-conduct and also make it faster to turn off. For example driver cap will be 1u, C1 100n, gate C 10n.
Hi,
I'am running my FSESC 4.2 with FW 5.2 and anti spark switch. Is there a way to deactivate the 'roll to start' function ?
best
