Powering A Hard Drive Motor

Even 1-2 kW from tiny little brushless motors is possible... I suggest soldering additional wires like the photo above) Testing which lead is common Fig 2 Usually a hard disk BLDC is a 3-phase BLDC, which has 3 phases + 1 it mandatory to drop this value in order to reach the maximum speed . The connection between the microcontroller and the HDD motor are: PA0 (TIMER2-output) -> connected to the FIRST Brushless motor input COIL PB4 (TIMER3-output) -> connected to the SECOND Brushless motor input

Is the stepper designed with a massive magnetic core that retains lots of residual magnetism, where the hard drive motor does not? I would appreciate any input you can provide on this. Rating is available when the video has been rented. How To Run A Hard Drive Motor They appear to be in great condition and I was hoping someone here might have also purchased these or know of a way to get the voltage rating and wire sequence

this kind of propeller need a more powerfull BLDC. Circuits To Run Hard Disk Drive Motor Always thought I would keep them for more drive storage space but then every couple of years newer bigger faster drives come out that dwarf the old units in capacity. Since we dont have a hall sensor, we cant sense the position of the rotor.

If you want to see the video go to the bottom of this page. We can identify the 6 phases before reaching the maximum speed, then the motor runnig for a while at around 4500 RPM and finally the speed drop because of cutting off

voltage detecting on any of the motor's coils when it is not being fired) which in turn could help the exact firing of the next (round of) pulses. http://theamateurprogrammer.blogspot.com/2014/02/revitalizing-old-hard-drive-motors.html To correct this this, like Hermann MK said, we have to determine the "optimum signal interval" (Kudos!

Keep 'em coming! Hdd Motor Pinout They have all coils connected (I am guessing). On the left hand side of the image, I just soldered 4 wires to the back of the motor.

You may still get some problems because at low speeds the pulse might cause it to step too far and not be able to get in sync' with the next.

I hoped to find really fast, torqueless motors inside. Increasing voltage allows shorter cycle period (prabably due to a stronger torque => higher rotation speed) Addition info: I dismantled / disassembled one of the BLDC motor, shown below: The 4 And per Ken, keep cracking on that Prop2 layout!

Principle of reflexion : The microcontrollers use a PWM as input to calculate the time separating between two light-cutting. This technique is also used in RC model motors, although they usually just have three wires (no common). So as long as I have them, I may as well put them to good use. Using a wall plug as a 12v source instead of the batteries will work right?

Please continue your commenting here.  I am the proud owner of a stack of scavenged hard drives. Once one serial pulse makes it into the 74164, the system will maintain the sequence. The one exception is during startup. The platters need to spin at a constant velocity for the data to be read so the "steps" produced by a stepper motor would not work.

I wonder can you help me, because I don't know where to look for a problem.ReplyDeleteRepliesRanjan TiwariAugust 19, 2014 at 6:10 AMHey, I tried the second code (the first code needs Got a 30A ESC and Servo Tester. Stephen Smith 127,362 views 1:30 How To Run A HDD Motor Or Wire A 3 Phase To Run From A Single Phase - Duration: 10:56. Several external connections control things like fan speed (via PWM), soft switching and startup commutation time (how long the chip spends looking for a valid back EMF signal).

You could in theory use the FG output to do closed-loop control of the motor speed using a separate microcontroller. See more. To reverse the motor, it should be a simple matter of swapping any two of the phase connections. Beau Schwabe 11,041 views 1:21 Free Energy Light Bulbs - Duration: 5:02.

The two coils: brown/orange and red/yellow There isn't much that can go wrong with a stepper, the fact that you are getting an omic reading is good. So A proposed driver circuit might be composed of 4 Half-Bridges (See HD Drive.jpg) Edit Here is a circuit that will spin up the hard drive to a high speed.
