Anyone able to help me here?
I can see this new VESC doesn't have a switch to change the sensor voltage from 5v down to 3.3v, has this feature been remove or am I missing something?
Cheers,
Ali.
Hi,
Hi! I have a zero 11x electric scooter, and i'm looking to go "big" when it comes to power. Right now i have about 7.2kw, 50A per wheel with basic BLDC controllers from Minimotors, and as we are speaking i am making a second battery to wire up in parallel to have a total discharge of 200A at 72v (20s). My question is the following:
I'm curious if someone has guidance and/or tuning tips for utilizing vESC in a propeller load (fixed-wing) scenario with duty cycle or speed/rpm control and FOC motor control. The biggest issue I'm experiencing is a lock-up and stutter/screech when increasing input via speed or rpm control (using UAVCAN input) fast from a 0 ERPM start. Once the propeller is spinn, say ~5000 erpm, then rapid increases are a non-issue. I'm assuming what I'm experiencing is the observer losing tracking because the motor can ramp fairly quickly without a constant load (prop vs surface).
brand new flipsky 6.7 dual fsesc, anti spark switch, and vx4 remote
constant power to esc, switch wont turn off, and motors wont turn, no cogging or anything. remote is connected successfully so i dont think that is the issue.
they worked fine during the set up
Hello,
I just buy a 65121 flipsky's motor and a "Flipsky 75100" ESC. My goal is to make a counter current swimming machine. So i don't use a remote, but a PWM control knob.
I followed some tutorial, and i managed to make it turn, but the current is too low at 95% duty cycle.
Do you know how can i increase that ?
The perfect case would be to have a amount of current compared to duty cycle.
Thanks for your reply
hello can someone tell me what is the best vesc for our purpose for a boat for fish watching for several months in the sea. Longevity and efficiency is the most important thing here, but also electrical or acoustic interference should be reduced to a minimum (the motors are most likely only operated at approx. 125W and low speed. Motors with sensorless 70kv 48v and approx. 30A should be operated (the manufacturer writes but you should min. 100A esc use why we haven't understood yet)
Hi all!
I've been experiencing a jittery motor. Almost like the position tracked is not accurate and it "skips" one pole. It only happens when with moderate to high requested current at moderate to low speeds. The strangest part is that it only happens when applying torque in one direction (braking while going forwards or reverse accelerating)
Heres a short video demonstrating what I'm talking about: (audio on)
I want to connect a bluetooth module to communicate with the controller via a mobile application, but I don’t know how to do it correctly. I have no practical experience, can you explain the algorithm of work to me?
The nRF52832 module according to the manufacturer's firmware with uart support is preinstalled
I connected pins rx---tx, tx---rx, vcc---+3.3, gnd---gnd.
but it is not activated when the controller is started, what actions are necessary for it to work?
I can't download the application for Windows, when I try to purchase any of the versions in the cart, the product is automatically deleted after I click checkout, this happens on different devices, what's the matter?
please help me, I purchased the version for android, but this is not enough, I need to figure out how to connect the bluetooth module
in the tab of my files on the site, there are also no files with the ability to download
