I guess one of the next steps is to lay out a circuit board that holds all the parts other than the power stage.
yes that is the plan, working on the layout now
did some more testing in sensored mode.
the motor locking up like i showed in the last post still happens, but after some tries and turning the motor by hand i can get it to run.
whitch tells me it is probably has to do with the calibration of the current sensors. this motor has a no-load current of around 1-2A so that is part of the problem. i will get some acs714 sensors in my next mouser order to do some more testing on this.
in the vid below you can see the motor locking up in the beginning, then i got it running. the noise is coming from the frame the motor clamped in, the motor itself is really quiet. the second part of the vid shows some abnormality of the controller. after i release the throttle it almost fully spinns down, but then applies some throttle again. could be some noise on the throttle line, because i dont have the filter in place. (i did program the throttle with a small dead zone)
just remembered something, could this have something to do with the controlled slowdown?
i also did some tests with my outrunner RC motor. to get the push start working. so as you suggested i turned off the combfilter. that really didnt do anything noticeble. when i apply throttle, the motor turns 3-5 degrees to line up with a pole on the stator an then just stays there. it is really hard to turn the motor by hand when throttle is applied. an other thing that sometimes happens, it turns for a quarter turn, and then goes to drive 0.
