Full Throttle direct after input deadband

Submitted by toerde on Sat, 2022-04-30 18:54

Hello,

I have following setup for the use in a e-foil board:

- Motor: Flipsky 65161 / 100kv

- Controller: Flipsky FSESC 75200

- Remote: Flipsky VX3

Unfortunately, I can not regulate the motor continuously, rather digital, on/off.
Finger carefully on the remote and ...
When the value of the "input deadband" (15%) is reached, the controller immediately delivers 95% duty and the motor reaches its maximum speed.

VESC output current decreasing in time

I'm testing a VESC 75V 300A version from Trampa Boards to drive Motenergy ME0907 motor in sensored mode. It works well overall, however I noticed one problem: if the load is high the controller seems to be reducing the motor current which I guess it could be doing to prevent MOSFET overheating. However based on the temperature readings the MOSFET temperature is lower than the cutoff temperature. Basically the reduction in output current starts happening at around 70C degree, while cutoff start if set at 85C.

Insufficient torque at low RPM

Hi everyone, 

I'm using VESC 75V 300A version from Trampa Boards to drive Motenergy ME0907 motor in sensored mode. This is used for an electric vehicle. We are testing VESC  as a replacement for Kelly KLS controller. VESC works perfectly and in pretty much every way it's better than Kelly, however there is one problem - insufficient torque at low RPM which is a deal breaker. Kelly provides higher torque. 

Is there any VESC settings that I could tune to fix this issue?  Thanks

  

 

Sudden drop in speed after releasing throttle in FW mode

Submitted by shokrabi on Sat, 2022-04-23 15:05

Hi guys, I am using the vesc 75/300 with my sur ron build. When setting field weakening above 80amps the top speed is significantly increased compared to below 80a but the speed is not stable and fluctuates + - 3mph as well as sudden full braking when rolling off the throttle at top speed. This issue does not happen below 80a of field weakening but the top speed increase is not substantial. 

Is there any related settings to smooth out the field weakening power that I can experiment with? 

Thanks

Bluetooth LE not working with Vesc Tool 3.01

Submitted by Gatze on Fri, 2022-04-22 19:31

Maybe I'm missing something, trying to connect with Vesc tool to my Vesc 4.12 with a nRF51822. Tried on Windows and Linux. On Android everything is working. I can see the Vesc in the bluetooth options on both Linux and Windows and in the tab down in Vesc Tool while refreshing I can see only in Linux the Vesc.

Do I have something to do in the operating system it self like pairing or setting up the device ?

Using Vesc Tool 3.01

[Edit]

Already working in Linux, did not choose the right device in the dropdown menu after refreshing.
