Changing current sense output offset

Submitted by bww129 on Fri, 2024-03-15 05:27

I've searched through the code but can't find any defines for changing the current sense amplifier output offset voltage. The DRV8302 current sense amplifiers have a linear output range starting at 0.3V, so it would make sense to offset the output at 1.80V instead of 1.65V. The easiest way to do this on the DRV8302 is to use a voltage divider off the 5V supply because of the DRV8302 internal voltage divider resistors, BUT there don't seem to be any software defines that configure this voltage.

Good afternoon everyone! 

I hope that you are doing great wherever in the world you might be. 

 

After getting more and more familiar with the VESC software and also some Python incorporation that can be done with the PyVESC module, I am trying to build a project where I run both of the motors that I purchased previously from Flipsky, "63100 170KV 5500W" & "7070 110kv". 

 

VESC 75/300 + Scorpion 7050 300kv for Combat Robotics Weapon

Submitted by DabbingSnail on Mon, 2024-03-11 22:27

So basically I want to use the VESC 75/300 with a Scorpion 7050 330kv Sensorless Motor to spin a Flywheel of 13-14kg using a Pulley and belt system using 12S LiPo 6800mah 
The Motor will spin only in one Direction but i will also like to add the function to switch direction of the Motor in the event that the Bot is inverted 
I want help setting it up to be efficient without any twitching and the VESC to not reset during a match.
If anyone can guide me to the correct resource will be really helpful

Good morning everyone! 

I hope that you are doing great wherever in the world you might be. 

 

I am new to VESC and I have been trying to create a comparison of different motors that I purchase from Flipsky. I have the model "63100 170KV 5500W" and also the model "7070 110kv". My main goal is to export some recorded data of the motors in the 'Experiment' sub-menu from the 'Data Analysis/Realtime Data' menu. 

 

Motor Specifications

I couldn't find a thread cataloging this information or anything, but I recently had to disassemble my motor and actually remembered to count the poles and teeth on the gears. 

 

I've got a Himiway Cruiser which utilizs a 750W Luxwange geared hub motor. This motor has 18 poles, and uses planetary gearing in which the sun gear is 18T, planetary gears are the usual 36T, and the ring gear is 90T. This gives it a 1 5.65 ratio, if I'm doing that equation correctly.

 

MTPA

Is it bad to use field weakening and MTPA at the same time?

why choose the "target" or "measures" option over the other?

 

the description in Vesc tool is scary talking about possible fire and locked breaks "if you don't know what you're doing".  I only know I have an ipm motor which it's supposedly appropriate for.
