| Jun 25, 2018 at 21:38 | comment | added | pacman | this is a unipolar motor and you use A1 to A2 for example. which makes the end to end resistance double and reduce the current to half. You can get something similar to 32mA by applying A1 to GND. | |

| Jun 25, 2018 at 18:59 | comment | added | Anurag | I can try creating a driver circuit too, but I have a feeling that if I am not able to see it moving in small angles by applying manual power in the correct sequence, then I might run into the same problem with the driver circuit too. Do you think my understanding is correct? | |
| Jun 25, 2018 at 18:57 | comment | added | Anurag | Hey pacman - Thanks for the detailed reply! Yes, I will construct a driver circuit when actually using this motor. Regarding the steps you mentioned for testing it manually, I am actually following the exact same steps, but for some reason, the motor is not moving at all. I followed the following sequences - A1, A2, B1 B2; A1, B1, A2, B2; B1, A1, A2, B2. No luck :( . Could it be that the current being drawn through the adapter is less than 32mA? But I used 15V battery too through which certainly much more current can be drawn. 32mA seems not that much. What am I doing wrong? | |
