If you mean the motor proper, it's likely a 'stepper', in which case it is -in essence- a poly-phase AC motor (sort of) -- In the case of a servo (i.e. 'encoder motor') arrangement - you need merely apply the power and observe the direction of rotation...How to determine negative and positive of the hard disk motor...anyone have a good idea. Thanks in advance
I read somewhere the harddisk motor is a brushless motor and it requires special circuit to power it...do u have a simple schematic that i can followIf you mean the motor proper, it's likely a 'stepper', in which case it is -in essence- a poly-phase AC motor (sort of) -- In the case of a servo (i.e. 'encoder motor') arrangement - you need merely apply the power and observe the direction of rotation...
On the other hand: If you are referring to the motor+controller as a unit -- the easiest method of determining connection assignments is attention to same during disassembly - Given more information I'll be happy to offer further assistance

Correct -- they are generally (albeit, perhaps, not exclusively) of the form of 'stepper motors'....I read somewhere the harddisk motor is a brushless motor and it requires special circuit to power it..
Not to hand -- However if you are certain that the motor in question contains no integral electronics you may determine it's winding characteristics via (electrical) observation of the lines while manually rotating the spindle - whereafter application of 'generic' stepper-motor controller design applicable to said characteristics is a straightforward matter! -- Please be advised that a far less labor intensive approach may be realized via salvage of the spindle motor controller along with said motor!do u have a simple schematic that i can follow
It looks old so most probably.If you mean the motor proper, it's likely a 'stepper',
FWIW I'm using the term 'stepper motor' v-e-r-y loosely!It looks old so most probably.

@Papabravo I must confess -- I like your explanation much better!You have to provide commutation signals in the proper sequence to get it to move. In that sense the motor has no polarity.
Do you know any simple circuit to run it like transistor? Most of the one i found on Google using IC which i don't haveYou cannot just apply power to the motor and have it run. You have to provide commutation signals in the proper sequence to get it to move. In that sense the motor has no polarity.
Fabrication of a controller from 'discretes' is both 'fiddlesome' and labor intensive! -- Again, it seems your best solution is to salvage the controllers with the motorsMost of the one i found on Google using IC which i don't have
