Hard drive motor is brushless motor. It works with high frequency 3 phase voltage from ESC. However in this video, I tried to run it without ESC. by adding a capacitor. The capacitor creates a 90degree deflection angle. The motor will run, however at a much lower speed than the ESC.

All my projects are free, I design them on EAGLE 6.0. I uploaded it to Google drive. You need to use a web browser to download the file and open the file with winrar software (extract) on the PC. Open schematic file (.SCH) and PCB file (.BRD) with EAGLE software.
Hope you enjoy my videos and projects. Like, share and don't forget to subscribe to my channel. one more thing, thanks to everyone, my channel has reached 68K subscribers.
