Hello,
I have harvested the gubbins (guts) from two hard drives. I am trying to figure out how to make them run at full speed all the time so that I can use them as gyroscopes. They turn on for only a few seconds as things are now. presumably because the circuits are designed to shut down the spindle if anything is wrong with the drive.
I do not remember the brands of the drives.
these are three phase brushless motors. 12 volt
the driver chips are:
HA13626
and B996W0411 (I think this is the driver on this one, not 100% sure)
the first question is. since the motors and chips are still on the board, is there a set of pins I can jumper to make the motor go?
...and...
could the board be modified to better suit the task at hand?
if not, would I be better off to try get a tunable three phase BLDC driver or trying to reuse the chips that came with the drive?
note: I removed the case. arm and all other parts that are not needed, in order to reduce the weight.
