I have an old WD 40GB IDE HDD motor and its circuit board with me. Is it possible to run the motor with a battery with the circuit board attached along with it? I can post a picture of the circuit board if anyone needs it?

Update: I'm attaching the pics of the board in case it might help.Thanks

  • \$\begingroup\$ Yes it's possible - but you'll need a different circuit board instead - a BLDC motor controller. If there's no reason to make or buy one, might as well stick with the original. \$\endgroup\$ – Brian Drummond Feb 17 '17 at 19:57

    \$\begingroup\$ Most HDDs will actually spin up the motor when you apply power to the board (any power source of the right voltage(s) will do). However, if the heads are gone most HDDs will power down after a short time, some have internal sleep timers so they spin down even when everything's set up normally. But if you want any kind of control, you'll need a controller for driving "brushless" motors as HDDs don't use ordinary DC motors. The same sort of motor controllers are used in a lot of hobby stuff (e.g. RC planes and helicopters) and work quite well, just search for "brushless ESCs". \$\endgroup\$ – Sam Feb 18 '17 at 0:09
  • \$\begingroup\$ @Sam Yes i saw a few clips on Youtube people running them with a Brushless ESC. I have a dozen IC555 with me which I was planning to make a driver for the motor in case its very difficult or not possible to make it run with the attached circuit. \$\endgroup\$ – Rahul Salin Feb 18 '17 at 19:50
  • \$\begingroup\$ Just thought thought I'll update. Didn't ahve much luck with the ide hdd but got a similar old SATA HDD and connected it to ta SATA power sommector I had previously salvaged from an ATX PSU. I connected it to both 12V and 5V and the HDD did spin for a while then it was spinning again and after like two cycles it stopped had to reset power to continue spinning. \$\endgroup\$ – Rahul Salin Apr 4 '17 at 4:32
