Hi every one.
I've made a small size 3D printed outrunner brushless DC motor but it is not working. It has 9 stator slots with ABCABCABC winding pattern and delta connection with 14 turns, 0.6mm wire per slots, also 6 magnet sets attached to rotor with NSNSNS pattern (blue color print). Also I printed the same size motor with 12N 14P with the same wire and turns (white color print), as attached photos. The magnet sizes also are 15*3*2mm for white one and 15*7*2mm for blue one.
When I connect it to the 40A, 12v ESC, it is drawing 2A from my DC power supply unit and start to vibrating and turning a bit with continuous noise which you can hear in the attached video.
I also connected it to more powerful PSU and it starts to draw about 5A with the same symptoms but stronger.
I checked the winding directions and points of delta connection, and also polarity of the magnets many time but no luck.
If you need I can also share you the SolidWorks drawings.
Thank you in advance.
