I left all default values like recommanded, and the sensor cables of the motors is plugged in. Something that I noticed : when I do the “start detection” on each motor, it spins fine, then brakes making the beep noise. Sometimes it looks like it struggles to brake. as a consequence the BEMF coupling detected if very high (around 1500-2000) whereas when it doesn’t struggle, it stands around 800 like the other motor.
My questions are:
is my motor broken?
what can be wrong with my motors and how can check that?
are default values good for my build ? or what should I change ? to what values ?
I’ve always had trouble with motors spinning sensor(don’t know if I’m doing something wrong) but I’m always getting good result sensorless.
And if using ppm splitter you are suppose to cut one of the 5v off
Yes you should. Get the 5V only from one focbox.
Take away the tick at limit max erpm with negativ torque please. That means if you reach full speed your focbox would make a full break.
Something you don’t want!
Try this both first.
If it not work, try to set up in FOC sensored.
Should be no problem with focboxes.
They Already in your screen shot…
My fault. Didn’t use bldc tool long time.
The settings are for 10s.
They too low for 12s. That will not fix your motor problem but please set it up to 3.3v per cell start and 3v per cell end.
So 12x3.3 and 12x3
Motor detection should be done always without load, so no belt attached.
It is like this at the moment?
Can you spin the motor with your hand?
Do you hear any grinding noise or one motor turns worse than the other?
