VESC Tool

Hi,

For my esurf project I´m running a
*Trampa VESC 75/300
*MHZ Scorpion 7455-320KV 22.4kW (sensorless) 2200grams
The issue I´m having is that I can´t get this motor to work basically.
I´ve ran it through the motor detection in VESC tool and there it spools up and all but it´s very "jerky" when it does the small steps in the end.
And as soon as I try to give it some throttle afterwards it´s stuck.

I´m not sure what to test at this point, and I don´t want to fry anything cause of some stupid setting I try.

Hello!

I have a flipsky 75100 and I am trying to use regen with my 1500w direct drive motor. I have the max regen amps at -30 and the same with max battery regen amps. I have my brake levers set up correctly and have even tried setting the ADC input to make my throttle act as a brake after center voltage. After all this the bike does not regen under braking. Any help is greatly appreciated!

I upgraded my VESC tool to V3.01 and also my firmware of my VESC to the latest version. Since then, I receive the message "Could not get Positioning Working", when I want to start the log-file recording.

Nevertheless, the recording works, however I'd like to know, what is behind this message.

I have a motor without hall sensors, however I installed an AS5047 encoder at the end of the shaft, which works.

Can anybody help?

Regards,

H.-P.

.

Version 2.06 worked totally fine. But i was interested as the message "Updated Version 3.01" came out. So i downloaded it and gave it a try. Nothing worked.. Programm wont start at all. No Problem - back to 2.06 but no. Now 2.06 didnt start now ether. I dont know what to do. This makes no sense for me.

Any Ideas?

Hi,

really a strange problem with the VESC 100/250 (two of them, on both). Whatever I try, I don't get the VESC 100/250 to run above 150A (~155A) Motor current.

Even though I raise the Motor current to 220A and the ABS Motor Current to 400A, at 150A maybe a little above, the VESCs shuts the motor down. 

I tried to set the FOC

* advanced v0 and v7, enabled, disabled

* ABS Fuse slow

* High current measurement disabled/enabled

The Motor can hold at least 180A for 15seconds.

Running on 2x7s batteries.

Hii, 

For my thesis am i making a electric scooter. Yesterday after i did the firmware update, a connect has lost. Today I i soldered it back together but when i wanted to connect the VESC to the vesc tool, it said "Could not autoconnect. Make sure that the USB cable is plugged in and that the VESC is powered.". The green and blue LED are together always on.

I hope someone can help me out.

Hi,
I connect an ABI encoder from the output shaft of a motor with a gearbox that has a 100:1 gear ratio. The BLDC motor is about 500g so I chose medium size in-runner in the motor FOC. When running setup motor FOC, the motor detection result shows it is sensorless. My guess is that when it tries to sense the encoder, the output shaft is barely moving due to the large gear ratio and the VESC cannot detect if there's an encoder. Could that be the reason why it is unable to sense the encoder? If so how can I fix it?

Hello everyone,

I am trying to control my outrunner AXI 2814/28 motor with the Flipsky Fsesc 6.7 70A controller using Vesc tool 3.01 under Windows (in sensorless FOC mode, BLDC mode is too noisy, which is crucial in this application). What I want to do is set electrical RPM here (via USB) and get the motor reaching smoothly this speed (the motor load is a propeller 11x5):

On previous versions of the Vesc firmware I implemented a cruisecontrol using a single actuator (thumb throttle) connected to adc 0. Not a big application, but it works nice. While on my bike I don't have to hold the thumb throttle all the time and can lay down on my triathlon steer. Of course safety is a big issue, but my brakes are always stronger then my motor and every little tap on the thumb throttle deactivate the cruise control. I used it for now like 10k kilometers without any hazardous situations.

Hello,

Can anyone post the min. hardware requirements of any smartphone / tab device, in order to run vesc tool smoothly ? I'm looking for old phones to make ebike displays. Any model recommendation ? Smaller is better. 

thank you very much,
