Need some expert advice on doing Torque Loading a BLDC motor Under Test.
I am working on a project where we need to characterize the e-bike hub motors and other motors of similar kind. The DUT (Device Under Test) will be driven by VESC. To load the DUT i have used Magentic Particle clutches in past.
Hi all.
I just got my first Trampa-Board today and within the package i also got the brand new wand remote controller. Btw. a really nice piece of kit.
In Benjamin's introduction video he showed a (imo. nice) feature: when braking fully, after a moment, the board will switch into a slow reserve so the board will stop or back up even when going down hill.
Mine doesn't do this. So i am wondering if maybe I have to update either the remote controller's or the vesc's firmware or both or if this may be just a setting somewhere which is turned off.
I haven't found any info on this, but it seems that someone could use the RX pin as an input and the PWM as a second input. Is there a way to use these two for a reverse and a brake switch?
I'm running a direct drive brushed DC setup. ADC1 is throttle with center brake and a button reverse. This is the only way I could get reverse to work properly, so I wired the brake to switch the high side of the ADC1 pot to ground (thus interrupting the throttle signal and achieving braking). The trouble is, as soon as you hit the brake, the wheels lock up. Is there a way to ramp braking on to save the gearbox from destruction? Ideally, I'd like ADC2 to control braking, but this does not seem to be possible.
Any ideas?
Hi,
I'm working on a VESC-based project. I saw the documentation , the VESC hardware used the STM32F40X controller with the 64 pin version . can i change the controller from 64 Pin with 100 Pin with firmware based on 64 Pin Controller?
Thanks before.
Hi there,
i would like if i can get some input from you guys, i'm trying to connect a mpu 9250 as external gyro to the vesc using vesc tool 1.17, how it is quite new release there is not much info about it.
i have connected the mpu as follows:
vcc= to vcc on the vesc
gnd= gnd
sda= sda
scl= scl
Settings in vesc, use external mpu 9x50 but not success. not data shows in vesc tool.
Any help will be very appreciate, thanks you all.
P.S maybe sda and scl are crossed like tx rx ?
I am currently designing a wireless controller that displays the VESC data (voltage, current, speed, etc.). I am using 2 arduinos that are connected to 2 NRF24L01 transceivers. The sending arduino is located on the skateboard and sends the telemetry data from the VESC to the receiving arduino. I am having trouble coding the transmitter side of the project as I do not know how to send the multiple variables to the receiving arduino. I am unfamiliar with this library for the NRF24L01 transceivers. Here is the code I have so far for the transmitting arduino.
I have a Flipsky 200a (vesc 6 based) esc and a turnigy CA80 160kv motor powering a go kart running on 12s. I have a 1:7 gear reduction on 10in tires. I have a few questions concerning the esc:
1. The esc says the motor is a 120a motor, but the manufacturer says it should be 200a. Is this a problem with the motor or esc or what?
2. When I take a corner quickly, the esc will sometimes cut out. Is this some kind of g force cutoff?
Hi everyone,
I have a problem with my electric board, everything was fine with my motor in the bdlc mode, but today i tried to move for the FOC mode ( lower noise is enjoyable :) ) but here is my issue : when no one is on the board it runs quite well, but with a load on it, sometimes the motor lose his trust for a moment and just after spin at full speed. I don't understand why, it is a pretty serious problem as you can see because it can quickly unbalance the user.
Is it my configuration on vesc ? or another problem ?
