This is a digital image of the motor deisgn with the Rotor in transparent color Figure 1

Motor side view Figure2

I started by doing 150 turns on each coil making sure they were winded in the same direction, then connected the starting point of each coil together and took each phase winding to be connected to my electronic speed controller. The magnets on the rotor were set up in the manner seen in Figure 1 (N35 10x2 magnets) and after bearings were placed and rotor installed, i connected for testing.

I noticed that the motor was not rotating as expected instead there was stutter which felt like there was opposing movements and attractions weren't in sync, just to make sure it wasn't stuttering because of too much friction i tried turning the controller off and on quickly and at random points i would see movements in the motor. This was the first time for me to come across such placement which i adapted from a video on YouTube (https://www.youtube.com/watch?v=MTCvwEugCeU) so i couldn't find much reading on the subject, can anyone help explain the inter-workings which stopped the motor from functioning so i can implement in my next design?

It is worth mentioning that I'm connecting the ends of the cords (out 1-3 Figure 3) to a RC car's ESC rated at 100+ amp draw and its connected to a 3S Lithium Polymer battery (about 11V)

UPDATE - Day 2:

I have tried the continuity test using a DMU and wires seem connected properly, when i tried the battery test i got vibrations but no proper 120deg movements, so i decided to go back to the simpler motor version by "amazingdiyprojects" and connected it and hooked it up to the esc, i still got stutters with esc but when i connected with battery test i got 120 degree movements with each phase, heres a video of the test https://youtu.be/C_D67JtDoj4 can it be the esc is sending rapid signals too fast for motor? i don't know what to do next

  • \$\begingroup\$ Wiring phases ABC of 3 coils wrong will do that like ACB or BAC. Does it have any torque? \$\endgroup\$ – Sunnyskyguy EE75 Mar 4 at 7:10
  • \$\begingroup\$ I couldnt get it to spin to test the torque, but im guessing for it to overcome the friction and sping like it did it must have some ( im using 0.25mm wire) i dont knw abt the ABC tho i mean the wiring is identical for the three phases theyre not connected to each other except the inlet of all 3 is soldered together \$\endgroup\$ – CcoderBeginner Mar 4 at 7:35

    \$\begingroup\$ "the inlet of all 3 is soldered together" but "theyre not connected to each other"... Perhaps you should draw a diagram of exactly what you have done. \$\endgroup\$ – Solar Mike Mar 4 at 7:49
  • \$\begingroup\$ The pigtails are common to Vbat but each other end must be in sequence to match the ESC which has colour-coded 3 phase wires which must be in the same sequence as your coils. But you can test with a D cell battery and see how each coil works for 120 degrees. The plastic should not have much friction if sanded. \$\endgroup\$ – Sunnyskyguy EE75 Mar 4 at 8:33
  • \$\begingroup\$ @SolarMike You're right, i added it now (Figure 3) \$\endgroup\$ – CcoderBeginner Mar 4 at 8:38
