Hello,
Some of you you may have read my other post, trying to run a motor in closed-loop velocity control with hall sensors.
I have now tried using the incremental encoder and going through the steps again. I am getting some strange behavior at this stage I would like to share and see what people think is causing it.
My Setup is:
ESP32
DRV8302 driver board
Maxon EC 1 30 motor
Maxon encoder 16 easy 1024 counts per turn
When I run the motor at 2 Volts. I get an initial speed of around 200 rad/s (1900 rpm) but it quickly starts slowing down although the voltage stays at 2 volts.
if I restart the ESP and it goes through the initialisation process and will start at 200 rad/s but slows down in a similar way.
If I run it at 1 volt I get 110 rad/s it slows down at a slower rate but it slows.
What might be causing this?
