Hi all,
Im currently building a large electric scooter im using the VESC 100/250 when i use the regen braking its cuts out like its pulsing off and on really fast. In the app i was getting an over current error but the regen is set at 10 amps and it still does it im running out of ideas on how to resolve this issue.
Cheers
Hello Everyone,
Here is a bench test summary of an efficiency measurement comparing a Flipsky 4.20 Mini VESC (Hardware 4.10) versus an Eflite 40a BLDC ESC.
The main Observation of this test is to measure changes in Wattage consumption changes while comparing the FOC method versus BLDC.
Measurements were done using a Turnigy V3 thrust stand and Power Analyzer
Issue :
When using the Receiver(Flipsky v2) to test the FWD/BWD ... the wheels don't go fwd and both motors make sounds but aren't turning.
Tho going back ''works'' but having a little hard time maintaining.
*The motors tho are running well when I do the detection test
When I try to setup the Input I do not see any feedback from the receiver in vesc ...
RT & RT APP are both activated ...
Im not able to pin point the source of the issue please help
Hi,
I started using this amazing Vesc controller, thanks to mister Vedder !!!
I'm using pwm interface to pilot the Vesc in FOC rpm regulation mode but I need too an erpm feedback via pwm for my autopilot.
Does anybody have an idea to do that via a software modification ?
Is it anyway to retrieve a proper sinusoïde on the pcb (hw 6.0) I could use to generate a pwm?
thanks in advance,
best regards,
Jean-Pierre
Hey everyone,
I'm have a problem with my scooter with flipsky 75200 ans motor 80100 80kv
,Top speed calculated 47km/h
Current setting in vesc 150 motor and 250 battery
For some reason whenever my speed Is 0-10 km/h the motor does not get current above 20-30a
But when is my speed is higher the motor get 110amp and 100% duty but at low rpm only about 15%
The battery is strong enough for the setup that I know for sure...
Why is that happening? It's like the controller doesn't give the motor the amppare at low speed
I am having a hard time calibrating the pid speed for a skateboard motor that has hall sensors
above 1000 rmp it seems quite stable but below 1000 at low rpm the engine shakes and I see the dudy clycle "vibrate" oscillate, lowering the values does not improve
I suspect that the problem is the hall sensor that at low rpm has little resolution, is it possible?
I would like to control my motor with the help of a power tool switch.This is a switch for BL power tools. It has 6 wires connection, which are gnd ,+5V, pwm, directionL, direction r, and one with x2+, no idea what this is.
Is there any possibility to connect this to vesc, and use it as speed and direction control?
Thanks

P.s. can I add pictures from my desktop to this post?
Hi, all.
I've been planning to make an R/C lawn mower for a long time and finally purchased two 10" brushless scooter hub motors and Flipsky Mini FSESC 4.20 speed controllers.
The idea is to use two independent drives in a v-tail configuration together wit a free rotating front wheel. Pretty basic stuff with normal r/c gear.
Now the tricky part. I set the ESCs and motors up in a rig where I can rotate them freely while adjusting parameters. Tuning phase is carried out with a 3 cell 2,2Ah LiPo-battery, controlled via usb-port.
So, I can't connect to my vesc I only get Acces denied how do I fix this?
Hi everyone,
Im looking for a little advice please.
