The solution is some sort of overkill ... but hey, they like to sell their chips :-)Try to find the motor controllers on old floppy disc drives and hard drives. First of all, note that a common hard disc drive (HDD) spindle motor is in fact a sensorless three-phase brushless dc (BLDC) motor! Some hard drive PCB's will allow the motor to spin continually and some will stop after a certain amount of time. As the name implies, a brushless dc motor does not use brushes. Recently I chanced upon an interesting small Chinese stuff named as “Knacro BLDC motor driver module” that followed the above idea for design (see its photo below). AFAIK HDD motors are stepper motors with 3 coils to supply input source at different phases of rotation of the motor. Since I know that designing a good brushless dc motor driver circuitry is quite a complex task, this $6 ‘universal’ driver board made me curious. A drive falling onto its side (as opposed to a drop from height) can and occasionally will seize the platter motor.-3.5” drives are much, much more likely to suffer a seized platter motor than a 2.5” drive. I need to get a harddrive motor up and running, it has four pins for power, does anyone know exactly what these pins or which is which, the motor is from a harddrive from an old xbox, i worked hard get this wretch out all the way down to the motor, honestly microsoft should build bomb shelters, and the casing of the hard drive is pretty tough, on of the boards on it needed some friendly persuasion from a hacksaw and a hammer after I removed the apparent retaining screws, all 7 million of them, by the way I may do an instructable on how to open an old Xbox with nothing more than a swiss army knife, and it doesn't get damaged at all. The motors all run pretty well - the hard drive motor is around 6000rpm with a 12V supply, and the ZIP drive motor is around 15000rpm (way too high for the original purpose!). some of the time the terminals are not marked and you must use guess work to connect what you beleive are the correct corresponding terminals on the parasite, sometimes if you connect the wrong terminals together the motor really struggles to spin without randomly changing direction , it may also spin but its low rpm and bery limpyyou gotta be really careful not to damage courier . The stepper motor is easy to connect same type of step and ditection signals as disk drives. Now you’ve the noble option of running your salvaged HDD BLDC motors either using your own circuits built around dedicated motor driver ICs, or by means of pre-wired boards/modules similar to the one already highlighted here (either idea would work and could be tried without an issue). This session details the hardware implementation of the Chinese brushless dc motor driver board. The next jumper P4, connected with the COM pin of the DRV11873, is for 3-wire/4-wire motor drive selection. phases - hard drive is 3 phase motor and fan circuit provides 2 phases only (it may still work with some inefficiency though) Following is the ‘footnoted’ version of the typical application circuit of DRV11873. It’s just another board similar to mine but with slight changes in PCB layout. After some tryouts, however, I found that the robust Chinese gem seemed to be able to fulfill my specific needs as it’s decently priced and much more comfortable. I could make an analogue version based on three contacts and the idea of a distributor, it would be needlessly complicated and very very useless but oh so fun to build... No, more like this, with the 4th wire being the center point. The 80s classic action series Knight Rider is being made into a feature film. They are mostly simple and cheap devices. power - hard drive motor is more powerfull than fan so it may overload the fan circuit Hard Drive Sander: Many people have an old hard drive laying around. Also, you'll need a second, identical hard drive motor from which you'll remove the rotor (which has a ring of magnets inside it). A typical brushless dc motor with three coils on the stator will have six electrical wires but in most implementations three wires will be connected internally, with the remaining three wires extending to outside. This is the bit where craft and patience becomes important: It is imperative that the platters are kept flush during the cutting of the slots. For the experiment, I simply followed the typical application circuit example (see below for an annotated version) obtained from the official datasheet of DRV10866. Your 4-lead motor probably has 3 coils (and "common"), and you get it to spin by applying power to each coil in the correct sequence. If you opted for the do it yourself option, it’s worthy to note that both TI chips (DRV10866 and DRV11873) are not very difficult to use if you’d special carrier boards (WSON/HTSSOP16) handy. This was tedious because of the defaced key components used by someone to build the board (what’s the fun in that?). The pre-wired board looks like this. You can also subscribe without commenting. Livraison rapide Produits de qualité à petits prix Aliexpress : Achetez malin, vivez mieux most hard dive circuit boards will spin the motor if you give them 12 V (without drive heads or ide cable connected), You can use a brushless electronic speed controller (Brushless ESC) like the kind used in R/C cars and aircraft. Surprisingly I got a cute board that has properly labeled key components. I'm glad you found this useful. I’ve seen many sensorless BLDC motor driver/controller modules and most of them are tailored especially for small applications such as cooling fan control. The onboard speed control potentiometer regulates the speed of the motor. It seems that the core part – the motor driver –  is a DRV11873, one 3-phase, sensorless BLDC motor driver from Texas Instruments (or its cheap knock off). Now to the lazy man’s slapdash jump! UPDATE : The URL for my instructional video above is changing, I'm dropping the Jaytube domain in March 2014. However, in a sensorless brushless dc motor, the back electromotive force (BEMF) signals are monitored by the driver to commutate the signal, instead of the position detected by Hall-Effect sensors. It also offers synchronous rectification pulse width modulation (PWM) operation, and sensorless proprietary back-emf (BEMF) control scheme which is pretty impressive. In general, hard drive motors work a little like steppers. Ensure that the external hard drive or internal hard drive is plugged in stiffly on your PC. They also have applications in aerospace, in biomedical and in driving cooling fans, etc. Older (or perhaps cheaper) drives … Hard drive is an electronic equipment’s and no one could have clear idea about when it can fail or become inaccessible.
